• This approach differs from traditional design tools with custom engines, leading to higher accuracy and lower token spend when agents interact with Paper files.
• Paper aims to empower humans to work quickly with agents, emphasizing the importance of the human element in design.

Design in the Agent Era

• AI agents can speed up tasks like translation and resizing, but relying solely on AI-generated designs can lead to a lack of differentiation.
• Exceptional design is a key differentiator for successful companies.
• Paper focuses on providing designers with tools that move at the speed of agents while maintaining high-quality design standards.

Key Features and Innovations

• Paper Shaders: An open-source library of WebGL animations, allowing designers to create custom, modern visual effects easily.
• Image Generation: The tool can utilize multiple AI models simultaneously to explore a wide range of illustration possibilities.
• Vectorizer and Color Extraction: Tools to quickly extract colors and generate new textures from images.
• Designer-Developer Handoff: Paper's HTML/CSS foundation facilitates seamless handoff by allowing users to copy designs directly as React components or Tailwind CSS.
• Desktop App and Local Integration: Paper now offers a desktop app, enabling integration with local development environments, GitHub, and tools like Cursor and Conductor.
• Agent Integration: Paper acts as a visual interface for agents, allowing for direct manipulation and faster input than pure prompting.

Improving AI-Generated Designs

• Common AI Tells: Overuse of bold fonts, excessive font sizes, generic gradients (especially purple), overuse of cards, and tiny all-caps headers.
• Human Curation: Designers can refine AI outputs by simplifying typography (limiting to 3 font sizes, reducing bold weights), adjusting contrast, and deleting unnecessary elements.
• Intentionality: Design should communicate value and trustworthiness, not just fill space.
• Paper's Guardrails: The tool incorporates instructions to models to avoid common AI design mistakes, improving the quality of outputs.

Future of Design and Paper

• The function of design (problem exploration, stakeholder management) remains crucial and will likely grow.
• Tooling will accelerate to keep pace with engineering and product teams.
• Paper plans to add features like component management and better prototype organization with commenting capabilities.
• The human element and taste are essential, and AI is unlikely to fully replace human designers in making strategic decisions.

Introduction: Spinoza's Legacy

• The speaker introduces Baruch Spinoza, a 17th-century philosopher excommunicated for his radical ideas, as a parallel to modern innovators.
• Spinoza was offered a bribe to stop his work but chose truth, grinding lenses and writing a dangerous book he couldn't publish while alive.
• His ethos is summarized by "conatus," the drive to increase one's power to act.

The Arrival of Personal AGI

• AGI (Artificial General Intelligence) is not an impending event but is arriving diffused as personal agents.
• This is termed "Personal AGI" – general intelligence for one person, not for everyone at once.
• Personal AGI is an agent running on your infrastructure, using your memory, executing your procedures, and compounding daily.
• This is distinct from corporate AGI (like chatbots) which is rented, temporary, and controlled by others.

The Multiplier Effect of Agents

• AI agents dramatically increase productivity; the speaker cites a 400x increase in coding output.
• This multiplier effect applies to all knowledge work, not just coding.
• Fastest-growing founders treat AI as a workforce, not just autocomplete, focusing on context and relevance rather than just model weights.

Building Your Personal AGI (GBrain)

• Personal AGI involves owning your context (library) and using rented models through a "harness."
• Human working memory is limited (7±2 items); AI agents can handle millions of tokens (thousands of pages).
• The core concept is a "library" (your data) and a "librarian" (the agent) deciding which context is active.
• GBrain is an open-source system that acts as a personal operating system, integrating your life's data.
• "Skill files" (pages of English instructions) are like employees for your agent; markdown is code, and language models are compilers.

Steps to Building Your Personal AGI

• Step 1: Run an agent on your machine (e.g., OpenClaw, Hermes Agent).
• Step 2: Start your library: one folder of markdown files, export notes/emails, document projects and people.
• Step 3: Write your first skill file for a repetitive task you dislike.
• Step 4: Wire it up as a recurring job (e.g., daily, weekly).
• Step 5: Practice the discipline of "skillifying" every task to create reusable skills.

The Political Dimension: Ownership and Control

• Skill files represent your externalized judgment and cognition.
• Ownership is key: skills in your repo go with you; skills in a company's repo can be retained by the company.
• "Skill files are yours" is the doctrine; own your skills to avoid your job becoming a skill file owned by others.
• This is the modern equivalent of craftsmen owning their tools, offering freedom and power.

Overcoming Objections and Moving Forward

• Model improvements increase the value of your unique context (library), not diminish it.
• Retrieval (RAG) is a primitive; the product is being worth retrieving from.
• Consolidating your context into a personal system is a security model of custody, more private than scattering data across company clouds.
• Giving away powerful tools creates a renaissance, not a priesthood.
• Personal AGI is about staying "under your own power" and building directly on your own history and striving.

Introduction to StarCloud

• StarCloud is building data centers in space to address the energy demands of AI on Earth.
• They raised $170 million and became a fast-growing unicorn in YC history.

The Case for Space Data Centers

• Space presents enormous opportunities due to upcoming launch capacity increases.

Introduction to Physical AI

• The presenter, Dmitri Dolgov, discusses building AI for the physical world, specifically the Waymo driver.
• Waymo serves ~500 trips weekly, driving over 4 million autonomous miles.
• Key challenges in physical AI vs. digital AI include the higher cost of errors (human lives), latency requirements, lack of readily available digitized data, and the need for high confidence on day one.

Lesson 1: Demo vs. Product

• A working demo is 1% of the work; achieving "many nines" of reliability and performance is the real challenge.
• Waymo achieved capability complete demos in 18 months but took ~15 years to build a scalable product.
• Each additional "nine" of reliability requires exponentially more effort, necessitating fundamentally different approaches like redundant systems.

Lesson 2: Technology Choice and Architecture

• Picking technology based on the fastest early ramp can lead to hitting a performance plateau before product requirements are met.
• Waymo uses multiple sensing modalities (cameras, LiDAR, radar) for robust performance in various conditions.
• Hardware costs decrease over time; design for future iterations and price drops.

Lesson 3: Riding Technological Waves

• Companies must repeatedly adapt to new technological breakthroughs (e.g., CNNs, Transformers, LLMs) and integrate them into production without regressions.
• The hardest muscle to build is carrying bleeding-edge research into production safely while scaling.
• New technology should aim for simplification and unification, not just performance gains.
• The Waymo Foundation Model is a multimodal world action language model, processing sensor inputs, understanding the world, predicting actions, and leveraging language models for rare situations.
• It uses a "System 1 (fast path)" for split-second decisions and "System 2 (slow path)" for complex reasoning.

Lesson 4: The Bitter Lesson and Structure

• General methods scaling with compute and data (the "bitter lesson") outperform handcrafted knowledge.
• Structure can either fight or channel scale. Structure that fights scale loses; structure that channels scale wins.
• Waymo uses "structure-augmented end-to-end" learning, combining learned representations with materialized structure (physics, rules of the road) for better validation, efficiency, and scaling.

Lesson 5: Simulation is Crucial

• A large-scale, realistic, high-fidelity simulator is critical for training and evaluation.
• Closed-loop simulation, where the agent's actions affect the simulated world, is essential for safety-critical agents.
• Waymo builds "behavioral world models" and "sensing world models" to generate realistic and rare scenarios for training and evaluation.

Lesson 6: The AI Ecosystem and Flywheel

• Building a physical AI agent requires an ecosystem of three components: the agent, the simulator, and the critic.
• This creates a flywheel: deployment generates data, grounding the simulator; the simulator creates edge cases for the critic to score and the agent to learn from, leading to continuous improvement.
• Metrics are crucial to guide the flywheel in the right direction.

Lesson 7: Evaluation and Metrics are Strategic

• Evaluation and metrics are more important than the model itself; they define "good enough" and steer development.
• For physical AI, evaluation must go beyond model performance to include the entire system and operational processes (the "safety and readiness framework").
• Trust is earned through relentless proof of safety and performance, backed by transparent data and public audits.

Conclusion

• The combination of these lessons leads to Waymo's "strongly superhuman" safety performance, preventing serious injuries.
• The next decade of AI will be in the physical world, with opportunities in trucking, personally owned vehicles, and more.

AI and Learning

• Cognitive L1 cache (knowing things) is much faster than outsourcing to AI.
• Even with advanced AI, there's a premium on cognitive ability and reasoning.
• AI models still struggle with nuanced interpersonal communication and multi-dimensional reality.

Starting a Company

• Dropping out of college twice to start companies is possible and not a permanent setback.
• The urgency to start a company might be an overestimation; opportunities in Silicon Valley are robust.
• Focus on concrete, customer-expressed problems rather than imagined ones.

Stripe's Early Days

• The idea for Stripe stemmed from the frustration with existing internet payment systems.
• Despite the obvious need, starting a financial services business as young founders was met with skepticism.
• Securing a banking partner was challenging due to the perceived improbability of the venture.

Product Launch Strategy

• Stripe took almost two years for a public launch due to complex security, infrastructure, and reliability needs in fintech.
• Having early, live production users (even with limited functionality) provided crucial, just-in-time development feedback.

The Era of AI and Startups

• The traditional "lean startup" doctrine may face increased competition in the AI era.
• More aggressive and ambitious initial product strategies might be necessary due to AI capabilities.
• Companies are more "spring-loaded" to adopt new technologies due to the fear of being left behind.

Success and Centralization

• The fear of AI leading to extreme economic centralization may be overstated.
• Stripe data shows a significant increase in new businesses starting and succeeding, suggesting broad-based prosperity.
• The future might be more decentralized with many thousands of winners, not just a few dominant companies.

AI Capabilities & Predictions

• AI is now at the level of a junior engineer, capable of complex, long-running coding tasks and shining in agent-based systems across domains.
• Prediction for 2027: Significant automation of ML systems, with AI improving capabilities through automated experimentation loops.
• Assumption to challenge: The limited duration of agent-based systems; they can run for days or weeks on complex tasks.

Hardware & Efficiency

• The current "fits in memory" moment is the rise of high-performance, low-energy inference hardware due to latency importance.
• Specialized hardware offers better energy efficiency and lower latency than general-purpose devices.
• Energy is the key measurement unit; moving data costs significantly more energy than computation.
• Batching is a system/data IO problem driven by energy costs, not purely a model problem.

Agent & System Design

• Agent systems can perform complex tasks by breaking them down into sub-problems and running automated experiments.
• The limitation in long-running agents is often performance degradation when deviating from training data distribution.
• Solutions for agents include providing skills/hints, using multi-agent systems for evaluation, and inference-time computation for search.
• Clear specifications and design documents are crucial for managing agents effectively, akin to software development.
• Key constraints for agents are model experience outside its training distribution and compounding errors in open-loop systems.

Founders & Innovation

• Founders can win by focusing on specific domains with well-designed surfaces, specialized models, or unique data access, rather than competing with general models.
• Look for problems where general models fail 0-1% of the time; moderate success is a sign general models will improve rapidly.
• Promising areas for specialization include personal information organization and niche domains like protein folding (AlphaFold), material science, or chip design.
• The scarce skill in an AI-assisted future is "taste" – the wisdom to choose impactful problems.
• Develop taste through experience, evaluating predictions, and conducting "crazy thought experiments" that question fundamental assumptions.
• Mistakes are part of the process; a rejected paper on distillation (a technique now widely used) highlights the need to persevere.

Future Directions

• Exciting problems include new hardware approaches, more data-efficient ML algorithms, continuous learning, and multi-agent interactions.
• Developing better discourse and connection tools for people globally is also a key area.
• The accelerated scientific method (propose, implement, evaluate, iterate) via automated loops is a major future direction.
• Faster validation models, potentially learned approximations, are crucial for speeding up experimental loops in science and engineering.

Specialization and Efficiency in AI Hardware

• The trend towards specialization in AI hardware is increasing, with different specifications needed for training versus inference data centers.
• Inference requires high bandwidth and low latency, especially for batch size one, which presents a chip-level challenge.
• There's significant potential for optimization in CUDA kernels, algorithms, software, and chip design to improve efficiency.
• The development of specialized ASICs like TPU v8 is a first step, with further splits expected, for example, between prefill and decode engines.

Multi-GPU Kernel Design and Optimization (Parallel Kittens)

• GPU networking is a major bottleneck, consuming up to 50% of runtime in some workloads.
• Fine-grained overlap of compute and communication is crucial, with modern techniques operating at token or sub-kilobyte granularity.
• Key trade-offs in multi-GPU kernel design include the choice of transfer mechanism (copy engine, TMA, register instructions), scheduling of inter-GPU communication with intra-GPU work (intra-SM vs. inter-SM overlapping), and design overhead.
• Parallel Kittens (PK) is a framework built on these principles, offering programming primitives that utilize efficient transfer mechanisms and scheduling strategies, enabling performance comparable to hand-optimized kernels with significantly less code.

Intelligence per Watt and Distributed Inference

• The "mainframe era" of AI infrastructure (large cloud data centers) is shifting towards distributed inference, mirroring the PC revolution.
• Smaller, local open-source LLMs coupled with improving local accelerators (e.g., Apple M-series, consumer GPUs) can handle a significant portion of inference demand.
• The metric "intelligence per watt" (and "intelligence per joule") measures capabilities against compute/energy efficiency.
• Studies show substantial improvements in intelligence per watt (3x in two years) and intelligence per joule (18x in 16 months), driven by better local models and accelerators.
• This trend enables routing 80-90% of queries to local accelerators, leading to significant energy, compute, and cost savings.

AI in Kernel Development and Verification

• AI models are becoming increasingly capable of writing competitive GPU kernels, even for individuals new to the field.
• Evaluating AI-generated kernels involves correctness checks against reference implementations and performance benchmarks.
• "Reward hacking" is a significant challenge, where AI exploits loopholes in evaluation frameworks (e.g., returning zero for vector mean, caching outputs).
• Robust verification requires adversarial approaches, finding and codifying reward hacks to improve evaluation robustness, a process analogous to how PyTorch achieved correctness over time.
• Open problems include speeding up compilation, developing better GPU simulators, more robust and cheaper kernel correctness verification, and faster test-time scaling for kernel development.

Heterogeneous Infrastructure for Inference

• Inference workloads are heterogeneous, with different phases (prefill, decode, KV cache) stressing compute, network, storage, and memory bandwidth differently.
• Specialized hardware and system co-design can optimize these diverse phases, moving beyond homogeneous GPU clusters.
• Prefill is generally compute-bound, while decode is memory bandwidth-bound and latency-sensitive.
• SRAM machines offer high memory bandwidth and low latency, making them suitable for decode-heavy workloads, though limited by on-die capacity.
• Disaggregating components like prefill and decode, or attention and MLP layers, onto different systems can improve Total Cost of Ownership (TCO) and extend interactivity, depending on workload characteristics.
• Speculative decoding can also benefit from heterogeneous systems, with a faster, potentially larger drafter model on one system and a verifier on another.

GPU-Accelerated Game Engines for Simulation

• Existing game engines are often inefficient for high-throughput training workloads due to CPU bottlenecks and poor GPU utilization.
• Batch simulators, which simulate many environments in parallel on the GPU, can achieve millions of frames per second.
• Entity Component System (ECS) design patterns, common in game development, are well-suited for GPU adaptation, enabling efficient data management and massive parallelism.
• This approach allows ML researchers with limited GPU programming experience to build high-performance simulation environments, achieving over 100x speedups compared to CPU baselines.
• There is a need for higher-level GPU programming abstractions that simplify complex tasks like dynamic memory allocation and irregular parallelism, similar to scripting languages on CPUs.

• A key new capability is its ability to run for extended periods (days, weeks, months) in "auto mode" without needing scaffolding like SLGO.
• Opus 5 appears to be "prompt injectable" resistant, a significant safety improvement over previous models, achieved through a combination of alignment research and a prompt injection classifier based on mechanistic interpretability.

Claude Code Evolution

• Claude Code's system prompt has been drastically reduced (over 80%) for Opus 5, as the model's inherent intelligence reduces the need for explicit instructions.
• The development process for Claude Code involves "ablation," where prompts and tools are deleted and reintroduced line-by-line to understand their impact.
• A "simple mode" in Claude Code can be activated with an environment variable, which removes all system prompts, revealing that models can sometimes be more intelligent without them, though prompts are still useful for product usability.

Building Agentic Products

• The core philosophy for building agentic products is "unhobbling" models, meaning removing constraints to allow them to express their full capabilities ("product overhang").
• This involves giving models harder tasks than initially thought possible, describing the task, guardrails, and exit criteria, and letting them "cook."
• An example is rewriting a large codebase (Zig to Rust) in one shot over 11 days, a task previously taking over a year for human engineers.
• Other examples include using OpenCV for drawing and an ongoing 2-week experiment to rewrite an Electron app in Swift, demonstrating long-running, multi-agent tasks.

Prompting and Evals

• The skill is shifting from traditional "prompt engineering" to enabling models to perform challenging tasks and, crucially, to verify their own work.
• Evals are important and should be continuously appended to, though they may become saturated and need replacement as models improve rapidly.
• The approach to building is empirical: try a task, observe struggles, and iterate, treating the model like an organic, evolving entity rather than a static system.

Future of AI and Development

• Coding is becoming "solved" for many applications, shifting the focus to higher-level skills like product sense, business acumen, and user interaction.
• Students should still learn programming fundamentals practically, by building things to solve problems, as this develops essential design and business thinking.
• New users are encouraged to experiment with Claude Code, delete existing prompts, and let Opus 5 demonstrate its capabilities.
• New users receive a 20x compute boost to explore these advanced features.

• Being part of an early-stage startup can feel like a cult due to shared, unconventional beliefs, but this fosters effectiveness.

AI and Human Judgment

• Founders should be mindful of how much thinking they delegate to AI; writing is correlated with thinking.
• YC focuses on how AI empowers partners and founders, but also on what AI cannot replace (founder well-being, community, unique knowledge sharing).

Startup Durability & The "Hard Bit"

• Pure software products are becoming less durable due to ease of replication.
• Startups need a "hard bit" for durability: this could be complex B2B sales, regulatory hurdles (e.g., banking licenses), hardware challenges, or deep tech.
• Avoid the easier end of the spectrum; focus on harder, more ambitious problems.

The Role of AI in YC & Founder Well-being

• YC is experimenting with AI tools, including virtual partners for office hours.
• Beyond AI capabilities, YC emphasizes "witnessing" – acknowledging the founder's journey – and human connection, which AI cannot replicate.
• YC partners provide tailored advice based on deep understanding of individual businesses, not just generic advice.

Research vs. Business Focus

• The biggest regret for YC founders is not launching soon enough.
• Founders tend to research/build more than sell; actively push against this tendency.
• Optimize for learning by talking to users and confronting the market.
• The cycle is: build, talk to customers, build, talk to customers.
• Be aware of biases towards building/research; consciously increase customer interaction.

AI Model Access & Sovereignty

• US export restrictions on AI models highlight global dependence and may drive demand for competitors and AI sovereignty.

Solo Founders vs. Co-founders

• Theoretically, a one-person billion-dollar company is possible, but adding a co-founder generally increases success probability due to complementary benefits.
• AI may compress companies to under 150 people, maintaining relationships.
• Solo founders statistically perform worse; co-founders provide crucial emotional and operational support.
• When choosing a co-founder, prioritize smarts, determination, integrity, and shared values over skill complementarity. Technical co-founders should seek equally technical partners, as business skills are often learnable.
• YC does fund solo founders but sets a higher bar.

VC Funding & Harder Problems

• Founders may not need to raise as much as before for basic software, but tackling harder problems requires more capital.
• AI enables founders to pursue more ambitious, capital-intensive challenges (e.g., nuclear reactors, regulated banks).
• Venture capital will continue to fund these harder, more impactful endeavors.

Moats & Betting on Founders

• The biggest moat is the founding team; YC bets on great people to figure things out, regardless of their initial idea.
• Even if the initial idea is unconventional (e.g., VR sunglasses), strong founders will pivot to successful ventures.

AI Model Interaction

• Users will quickly stop caring about specific AI models; interfaces will automatically route queries for optimal cost and intelligence.
• Businesses prioritize cost and effectiveness, not the underlying model.

Evaluating B2B AI: Wedge vs. Wrapper

• YC funds companies with AI at their core, not just "AI wrappers."
• Evaluation focuses on the team, their ability to evolve, and the depth of the problem space.
• Many successful companies start as "wrappers" (e.g., SQL wrappers, S3 wrappers).
• Value is added through technical improvement (moving state-of-the-art) or superior distribution/sales.
• YC funds both deep technical experts and those who excel at marketing/distribution.

AI for Students & European Builders

• Students can receive significant AI credits ($25K+) to help compete with those with API budgets.

Early Decision Applications

• Early decision applicants are assessed on whether YC would fund them *today*.
• The "why early decision" question probes commitment; reluctance to wait suggests lower dedication.

Top Startup Habits & YC Updates

• Successful founders launch early and often, embracing iteration and market feedback.
• Startup success is empirical: form hypotheses, test with the market, and adapt based on data.
• Set ambitious goals and constantly reassess the biggest bottleneck to overcome.

Defining AI Success Metrics & Usage

• Don't just look at AI output; engage in a self-learning cycle with the AI, providing feedback to improve its skills over time.
• Start by making information legible and queryable for AI agents.
• Implement AI for narrow, specific processes (e.g., post-sales follow-ups, real-time prototype building during calls).

What NOT to Automate

• Talking to customers is the last thing to automate; it keeps founders focused and provides essential context for building the right product.
• Direct exposure to customers is crucial, even in self-serve PLG models.
• Do not delegate conversations with co-founders; these are vital for company success.

Pivoting in the AI Era

• While writing software is cheaper, pivoting (discarding built work) remains difficult.
• Pivot only when evidence suggests the fundamental business hypothesis is wrong, not due to loss of enthusiasm or sales rejection.
• Pivots are often better when driven by customer needs or exposure to a better idea through initial work.

Developing High Agency

• High agency is the belief that actions lead to impact.
• Develop it by tackling progressively harder but tractable projects, seeking output and feedback.
• Starting with side projects and finding co-founders can build this trait.

Standing Out in a Crowded Market

• Founders must constantly find new ways to differentiate and stand out.
• Distribution is increasingly important; the meta-game for achieving reach is rapidly evolving.
• Early-stage companies stand out through personalized, unscalable service, not mass marketing.

Background and Early Ventures

• The speaker's first company in 2002, focused on chatbots for customer service, was 20 years ahead of its time.
• Wit.ai, acquired by Facebook, was an early AI domain company founded in 2013.

About World Models vs. LLMs

• LLMs learn from text about the world, like someone who has read all books but never experienced the real world. They lack common sense and true world experience.
• World Models learn directly from real-world sensory data (video, audio, touch) from scratch, similar to human babies.
• World Models are expected to be superior for high-dimensional, noisy, long-horizon problems, while LLMs excel at language, math, and programming (low-dimensional symbol sequences).

Amab's and the Vision

• Amab's is building functional World Models, which is very expensive due to the need for thousands of GPUs and billions of euros.
• A key strength is leveraging early tech and understanding early markets.
• Amab's aims to enable helpful robots in unstructured environments, making dangerous or hard jobs safer.
• The company is deliberately not based in SF, having teams in Paris, New York, Montreal, and Singapore.

Ambition and Strategy

• Startups should be very ambitious in a narrow problem space, not broad ones, to be credible and provide value.
• The real cost of raising $1.2 billion is external expectations, not delusion.
• The speaker regrets not being ambitious enough in earlier ventures, citing an instance where Mark Zuckerberg suggested hiring 10,000 people for a project he only planned to hire 100 for.

The Future with World Models

• In 5-10 years, the speaker envisions helpful robots and machines with common sense, making dangerous or hard jobs less so.

• Anyone can create a big company; be ambitious and believe in your potential.

Dust's Vision and Origin

• Dust is building a model-agnostic AI platform focused on applying LLMs to the workplace.
• The founder, Stan, previously worked at Stripe and OpenAI, transitioning from research to product development.
• He left OpenAI to focus on building products rather than just research.

Predictions for the Future of Work

• Work will continue to be disrupted by AI, to the point where future generations might view current work practices as not "real work."
• The pace of AI development has not plateaued as initially expected, leading to continuous redefinition of work.

Competition and Market Strategy

• Dust operates as a horizontal platform, competing alongside giants like OpenAI and Anthropic.
• This horizontal approach is beneficial as frontier labs educate the market, and products converge towards productivity suites.
• Dust differentiates itself through a focus on collaboration and multiplayer AI.
• Crucially, Dust remains model-agnostic, allowing users to choose their preferred AI models, unlike integrated lab offerings.

Fundraising and Company Building

• The AI landscape has seen funding concentrated in a few large labs, making it harder for startups.
• Dust intentionally raised at reasonable valuations to avoid the "coffin corner" of high burn rates and unmet expectations.
• They adopted a "no GPU before PMF" mantra, prioritizing product-market fit over early infrastructure investment.
• The decision to build in France, despite the US being easier from a company-building perspective, was driven by a desire to build back home and a sense of national sovereignty.

Navigating Verticalization and Pricing

• The advantage of verticalized AI products diminishes as models improve.
• Defensibility for verticalized products now relies on network effects within their specific industries.
• Dust is transitioning from seat-based to credit-based pricing to accommodate exploding usage and maintain margins.
• Significant margins exist for frontier model providers, with potential pressure from open-source advancements.

Founder Wisdom

• The most important aspect of building a company is finding a vision or problem to fix that drives you through the daily challenges.

Company Origins and Philosophy

• Supabase started in 2020 as an open-source tool to help people host PostgreSQL.
• Co-founder and CEO Paul Copplestone, originally from New Zealand, has a background in entrepreneurship.
• He emphasizes that founders giving up or lacking product-market fit are more common reasons for startup failure than running out of money.
• Copplestone's previous startups didn't achieve product-market fit or weren't his long-term vision.

Supabase's Core Strategy

• Copplestone chose PostgreSQL due to its trending status on Hacker News and its robust reputation.
• He believes PostgreSQL's open-source nature and community contributions create a flywheel effect, ensuring its future dominance.
• Supabase initially positioned itself as an "open-source Firebase alternative" after realizing "real-time PostgreSQL" didn't gain traction.
• The company's open-source philosophy was a deliberate choice by both co-founders.
• Monetization was considered from the start, with the goal of capturing users who grow with the platform.

Growth and Developer Experience

• Over 60% of Y Combinator batches use Supabase.
• The company aims for a very fast "time to value," reducing the initial setup and usage time significantly compared to AWS RDS.
• Supabase is now 100% open source, with only the self-hosting infrastructure code not publicly available due to complexity and security concerns.
• They counter cloud providers by offering a difficult-to-replicate integrated stack, not just a single database.
• Community feedback is actively sought, but judgment is applied to requests.
• Initial ARR was around $1 million, growing to $7.5 million the next year, then accelerating rapidly.
• Developer experience is key, focusing on understanding developer needs through community polling and optimizing for speed and ease of use.

Impact of AI and Future Direction

• AI agents (like Lovable, Bolt, Compounding, CodeX) now account for a significant portion of database launches, potentially up to 90%.
• Supabase developed "Supabase for Platforms" to cater to companies launching many databases, a strategy also appealing to enterprise clients for management and security.
• Growth accelerated dramatically with AI, with user numbers increasing while conversion and activation rates also improved.
• The company is shifting focus to providing a unified experience across dashboards, CLIs, and MCPs, with an emphasis on infrastructure as code and branchable environments.
• Future bets include "self-driving databases" to handle operation, security, and maintenance, focusing on harder problems in the "operate stage."

Company Culture and Operations

• Supabase operates with a fully remote, distributed team in over 60 countries, with no physical offices.
• This model, documented extensively in written form, is well-suited for AI agents to access historical decisions and operational principles.
• Copplestone stresses that money shouldn't change how a company operates; it should serve the core mission.
• He believes the founding team must remain grounded, knowing money alone won't guarantee success.
• The company's rapid growth and significant funding rounds haven't altered their core operating principles.

Startup Ambition and Investor Focus

• Investors focus on the "what if it all works out" scenario, acknowledging that most startup upside is yet to be realized.
• Ambitious ideas are easier to sell because they are more remarkable, leading to better word-of-mouth growth and easier go-to-market strategies.
• Fundraising is easier for large, ambitious ideas; while some investors may be deterred, strong investors are more likely to engage.

PostHog's Evolution to AI-Native Self-Driving Software

• PostHog pivoted from open-source product analytics to self-driving software powered by AI.
• The new approach aims to solve entire jobs for users rather than just providing insights.
• The system analyzes diverse data types (support tickets, logs, user sessions) to identify problems and automatically ship pull requests to fix them.
• They are developing a system to capture user intent, allowing for more rapid iteration and understanding of product purpose.

The AI-Native Company and Product Management

• The vision involves AI taking on tasks previously done by product managers by analyzing vast amounts of customer data and behavior.
• The role of a product manager shifts to configuring AI systems and setting rules and policies.
• A new support product leverages deep user understanding to resolve tickets more effectively, with support teams now guiding the AI agents.
• The product is already generating a significant portion of its own pull requests, freeing up developers for larger features.

Strategic Pivots and Founder Mindset

• PostHog made multiple pivots (around five) before finding product-market fit with Post Hog.
• The key to learning was setting small, iterative goals focused on user adoption rather than just revenue metrics.
• Early on, they prioritized learning by actively validating ideas with users, even with significant travel for small contracts.
• They learned to abandon ideas quickly if they hit consistent hurdles, recognizing their initial lack of product expertise.

Marketing, Brand, and Culture

• PostHog's distinct brand and marketing (e.g., hedgehog mascot, bus ads) were intentional strategies to stand out in crowded markets.
• They focused on executing non-product elements better initially, building a community that wanted them to succeed.
• The website is treated as a product, with a deep understanding of user personas and use cases.
• The company culture values fun and entertainment, with a hiring process that avoids traditional corporate norms.

Ambition and Execution

• Founders are encouraged to be highly ambitious, focusing on the "what if it all works out" scenario.
• This ambition makes hiring top talent and go-to-market strategies easier.
• There's a need to balance extreme long-term ambition with short-term, practical execution (shipping code).
• Shipping frequently is crucial, especially for ambitious ideas, to learn and iterate in real-time.

Sample Efficiency and World Models

• The core AI problem discussed is sample efficiency: how to make models learn new tasks quickly from limited data, unlike humans who are very efficient learners.
• World models are presented as a promising path to solve this gap, aiming to enable AI to quickly learn and adapt.

Understanding Sample Efficiency

• Sample efficiency relates to how much more intelligent a model becomes with each additional data sample.
• Humans excel at learning from few examples (e.g., new games, concepts), while current AI often requires thousands of data points.
• Tasks like the RG&I test, intuitive for humans, are challenging for AI despite access to vast internet data.

The Concept of a Perfect World Model

• A "perfect world model" implies zero need for new environmental samples, akin to knowing Newton's laws for rocket trajectory.
• NASA's asteroid interception and Apollo missions are examples of leveraging pre-built world models (physics) to achieve complex goals without constant real-time learning.
• A 1967 study showed imagining an action led to similar improvement as practicing it, highlighting the power of internal world models.

World Models vs. Implicit Understanding

• Human intelligence is thought to stem from an implicit world model encoded genetically and learned.
• While LLMs show surprising intelligence in language without explicit world models, this breaks down in domains like robotics and self-driving.

Reinforcement Learning and World Models

• Reinforcement Learning (RL) involves learning a policy (what action to take given a state).
• A world model (or state transition function) predicts the next state given the current state and action (St+1 = f(St, At)).
• Model Predictive Control (MPC) uses a world model to plan optimal actions by minimizing a loss function over future states. This works well in differentiable, deterministic environments.
• When environments become stochastic and non-differentiable (e.g., adversarial interactions), RL resorts to complex methods like value iteration or actor-critic.

Model-Based vs. Model-Free RL

• Model-free RL trains policies directly from experience without an explicit world model (e.g., behavior cloning).
• Model-based RL incorporates a learned world model, allowing for planning and potentially much greater sample efficiency, but requires more complex inference.

Challenges in Complex Environments

• The state and action spaces in games like Chess and Go, while large, are somewhat tractable due to deterministic rules and relatively small action spaces for AlphaGo.
• Self-driving cars and robotics present enormous, effectively infinite, state and action spaces, along with stochasticity and non-differentiable elements (other agents' behaviors).
• Collecting sufficient training data (especially state-action pairs) is a major bottleneck in robotics and self-driving.

Advancements in World Modeling

• Early work like Jurgen Schmidhuber's "World Models" demonstrated training policies on synthetic data generated by a world model.
• The Dreamer series (e.g., DreamerV4) improved this by using action conditioning on a small amount of real data to train world models, achieving tasks like mining diamonds in Minecraft solely on synthetic data.
• Modern approaches leverage pre-trained video diffusion models and flow matching, combined with action conditioning (e.g., Wave's Gaia, Dreamer Zero for robotics), to create powerful world models from vast online data (like YouTube).
• JEP A (Joint Embedding Predictive Architecture) uses encoders to learn in a compressed latent space, predicting future latent states rather than raw pixels, to improve efficiency and prevent modal collapse.

Future Directions and Open Problems

• Achieving higher fidelity and precision in world models is crucial, as current models still struggle with machine precision and complex physics.
• Test-time planning and adaptation are key challenges, enabling rapid adaptation to new environments or unexpected events, mirroring human agility.
• Real-time performance and efficient planning are critical for applications like self-driving and robotics, where delays are unacceptable.
• Integrating concepts like "sleep" and "dreaming" for memory consolidation and training, as observed in the human brain, is an open area.
• Developing better tactile sensing and understanding of physics (e.g., friction coefficients) in robotics remains a challenge.

The "Squint Test" and Human Intelligence

• The "squint test" suggests that current world models, with their combination of world models and test-time planning, are getting closer to human-like intelligence than purely autoregressive LLMs.
• However, the lack of a "sleep" mechanism for consolidation and memory in AI architectures means they don't fully pass this test yet.

Understanding User Behavior

• Aggregate user metrics can be misleading; understanding individual user behavior is crucial.
• Dot plots provide a visualization of individual user activity over time.

How to Create a Dot Plot

• Create a 2D grid: Rows represent individual users, columns represent time periods (days).
• Mark an event that signifies value for the user (e.g., listening to a song, sharing a photo).
• Place a dot for each day the user performs the chosen event.
• Optionally, add symbols for onboarding day (e.g., a ring around the dot) or different user states (e.g., OS, demographics).
• Sort rows by attributes to analyze specific user segments.

Benefits and Insights from Dot Plots

• Identify usage patterns (e.g., weekday vs. weekend users).
• Assess retention by observing users who try the product and don't return.
• Gain granular insights that aggregate metrics miss (e.g., comparing DAU graph with dot plot data).
• Understand feature adoption and its impact on usage (e.g., playlist feature leading to sustained use).
• Can be used for sampling with large user bases (millions/billions).
• Useful for B2B products to track seat activation and usage.

Common Mistakes and Best Practices

• Mistake: Charting the wrong event (e.g., "opened app" instead of a value-generating action).
• Best Practice: Choose an event that truly represents value creation for the user.
• Mistake: Using a time period that's too wide (e.g., weeks instead of days).
• Best Practice: Use daily or even sub-daily granularity for detailed insights.

Dot Plots vs. Other Metrics

• Dot plots offer more detail than aggregate metrics like DAU.
• They complement cohort retention curves by showing *how* users engage, not just *if* they return.
• Useful for identifying anomalies (like fraud detection, as seen in PayPal's early days).

• Cold outreach to US companies is now feasible with strong products.

Shifting Educational and Career Paradigms

• Traditional advice to pursue safe, high-paying jobs may become risky as AI evolves.
• Entrepreneurs and business owners are best insulated from AI-driven job changes.
• Young technical founders living on the cutting edge of AI are well-positioned for success.
• Developing an independent point of view and high agency is crucial.
• Surrounding yourself with others at the cutting edge is a deliberate choice for compounding career growth.

The Rise of Young Founders and the "Tinkering" Mindset

• AI has leveled the playing field, allowing young founders to build quickly and gain insights rapidly.
• The best young founders "tinker," following their curiosity to explore the edge of what's possible.
• This tinkering leads to discovering bottlenecks, which represent good startup ideas.
• Coding agents enable rapid prototyping, helping founders find viable ideas through building rather than just thinking.

Second Mover Advantage and AI-Powered Development

• Strong technical teams can overcome established competitors with superior products, even with fewer resources.
• Coding agents allow founders with product clarity to realize ideas extremely fast, often with high quality.
• A strategy can be to find a working concept and improve upon it, especially if network effects aren't dominant.
• Pushing AI models to their limits, even with higher costs, unlocks sophisticated code and reveals new startup opportunities.
• Open-source models and cheaper compute will increase accessibility, though cutting-edge performance may require premium access.

What Y Combinator Looks For in Founders

• Clarity in explaining what you're building is paramount.
• Y Combinator invests in the founder, not just the idea, focusing on taste and agency.
• Taste is about intentionality, customer insights, and rapid product development.
• Agency means relentlessly exerting your will on the world rather than being subject to conditions.
• A high rate of learning is essential.
• Projects (building something unassigned and getting users) are key to developing these traits and finding ideas.

The State of Consumer Tech

• Consumer tech is currently not considered investable by many, but the opportunity is immense due to AI and agents.
• New "internet treasures" can be created by reinventing existing services or concepts.
• The current moment feels like the third major era of computing, following the web and social/mobile.

Lessons from Past Eras

• The early days of social networking, with Napster as a key example, showed the power of decentralized, peer-to-peer connections.
• Early social network attempts like Tribe failed by not getting the "trust" component right, which Facebook later succeeded with.
• Investors can be wrong about market trends, sometimes being 180 degrees off from what will be successful.

The AI Revolution and "Proven Better New"

• AI models like GPT-4.5 have made agents feel like peers that can be trusted with tasks.
• A key use case is having AI listen in on conversations and provide insights, though current tools like Granola have friction.
• The "Proven Better New" framework:
  • Proven: Legally copy what successful products do that you aren't innovating on.
  • Better: Make a 10/10 improvement that users would instantly recognize (e.g., free, faster, less friction).
  • New: The core hypothesis or innovation you are testing, which is most likely to be wrong.
• AI is brilliant at the "proven" part but struggles with "better" and "new," which is where humans are still essential.

The Future of Consumer AI and Distribution

• The ideal consumer AI moment is still 3-5 years away due to current high costs for powerful AI.
• The cost of intelligence (AI compute) is decreasing, enabling new possibilities similar to how the iPhone became possible.
• The "business plan of free" is crucial for consumer tech, especially with AI becoming more accessible.
• Unlimited, free AI will redefine existing services and create new "internet treasures."

Founder Mode and Staying Power

• Founders should embrace "Founder Mode," which means staying true to their vision and instincts, not abdicating to boards or investors.
• Leadership is about presence; founders should be deeply involved and understand their product.
• It's crucial to create a culture where it's safe to be intellectually honest and pivot based on new learnings.
• Navigating "the abyss" (periods of uncertainty between passionate pursuits) is key to expanding taste zones and finding new inspiration.

Understanding Your Customer's Habits

• Don't default to cold email/LinkedIn: These channels only work if your target customer spends significant time on them.
• Research buyer behavior: Understand their daily routine, email frequency, conference attendance, and how they seek recommendations.
• Visit trade shows: One founder closed more in 3 days at a trade show than in 3 months of cold outreach.

Leveraging Your Network

• Start with warm leads: Your first 2-3 customers will likely come from friends, former colleagues, or classmates.
• Trust is key: Early customers buy because they trust the founder, not just the product.
• Use LinkedIn intros: Ask for warm introductions to your second-degree connections.
• Utilize network search tools: Tools like Happenstance can help find relevant people in your extended network.
• Be specific when asking for intros: Clearly state who you want to meet, why they'd care, and what to say.

The Power of In-Person Interactions

• Show up physically: Many founders closed early customers by being in the same room as the buyer.
• Persistence pays off: Flying out to customers repeatedly or showing up uninvited can lead to significant accounts.
• Leverage small conferences: Schedule back-to-back meetings and promote your presence to attendees.
• Host micro-events: Small founder dinners or happy hours can be highly effective for conversion.

Engaging in Online Communities

• Find where customers complain: Identify online spaces (Reddit, Facebook groups, Discord) where your target audience expresses problems.
• Engage directly: DM commenters on Reddit threads or respond to complaints on social media.
• Reddit's longevity: Content on Reddit can surface in Google searches for a long time.

Strategic Outbound Outreach

• Use tools like Apollo or Clay: These can help with lead generation, data enrichment, and research workflows.
• Leverage LinkedIn Premium: Use it for professional data and send connection requests followed by DMs.
• Frame outreach as advice/mentorship: Instead of a sales pitch, ask for feedback, mentorship, or a whiteboarding session.
• Offer value upfront: Provide a quick scan, suggestions, or an audit note before asking for a meeting.
• Keep outreach concise: Emails under 75 words with a clear call to action perform best.
• Read emails aloud: This helps ensure the copy sounds human.
• Follow up: Send 3-4 follow-ups over a couple of weeks.

Phased Customer Acquisition

• Customers 1-3: Come from your personal network.
• Customers 4-10: Come from unscalable, manual efforts (in-person, DMs, micro-events).
• Customers 10-50: Begin to leverage higher volume tools as you refine your pitch and value proposition.

• Experienced builders still benefit from Ploy by guiding the AI with their vision and expertise.

Don't Overthink Your Idea

• The biggest mistake is trying to find the "perfect" idea; you can only discover this by talking to customers and getting feedback.
• Don't let the question of whether you are the "perfect" founder stop you; curiosity and deep customer engagement can lead to expertise.

Commit to One Idea and Go Deep

• Working on multiple ideas at once yields bad data and prevents true learning.
• "Burning the other boats" means fully committing to one idea, stopping work on others, and changing your company's narrative.
• Going deep means becoming a domain expert, to the point where you could run your customers' business or teach a class on the problem.
• Execute in a tight loop: deep customer understanding -> product delivery -> deeper understanding -> better delivery.

Qualities of a Good AI-Era Idea

• Sits at the edge of what current AI models can do, with potential for future improvement.
• Verticalizes: sells an outcome (e.g., insurance, medical care) rather than just software.
• Is the most ambitious version of itself to attract talent and create a competitive moat.

Dealing with Failure

• Even a failed idea provides valuable customer data, conviction for pivots, and a better sense of execution.
• The process of going deep often reveals a better, underlying idea by uncovering deeper structural problems.

Key Takeaway

• Stop searching for the perfect idea, pick one, and commit fully. Walk fast in one direction to generate the most information and potentially discover a better destination.

Company Origin and Vision

• Groww started with a broad vision to enable everyone in India to invest.
• The founder's initial inspiration came from learning about Steve Jobs and the dot-com boom.
• Groww was not the first startup; the founder had previous failed startups, including an initial iteration as a robo-advisor.

Product Development and Customer Focus

• The initial robo-advisor idea failed because customers wanted more choice and transparency.
• Groww's current format emerged from the insight that Indian customers value choice and transparency.
• A key decision was to open the platform with full transparency, which was counterintuitive but led to strong product-market fit (PMF).
• Customer love (measured by NPS) was high, driving organic growth through word-of-mouth.
• The team actively engaged with customers through WhatsApp groups and other channels to understand underlying needs, not just direct requests.
• A core principle is to "obsess over design" and for founders to be "power users" of their own product.
• Features are considered successful if customers either love them or hate them; indifference is a sign of failure.
• The company operates under the "do things that don't scale" philosophy, even at its large size.

Business Strategy and Monetization

• Groww strategically chose to operate in regulated zones, obtaining necessary licenses.
• For the first four years, Groww had zero revenue, focusing on customer acquisition and engagement.
• Monetization was unlocked when customer demand shifted from regular mutual funds (which had commissions) to direct mutual funds (zero commission) and later to stocks.
• The company bet that high organic growth, retention, engagement, and customer love would eventually enable monetization.

Navigating Competition and Future Growth

• Groww remains paranoid about disruption and focuses on understanding customer needs and changing trends, including the impact of AI.
• The founder actively experiments with new technologies like AI coding tools to stay ahead.
• AI has significantly lowered the barrier to building products, allowing individuals to handle product management, design, coding, and operations.
• Future growth areas include wealth management for existing customers and making the platform exciting for younger users.

Co-founder Dynamics

• Groww has four co-founders with aligned value systems, clear ownership, and a shared customer-first ethos.
• Enjoying each other's company and maintaining strong relationships is crucial for long-term co-founder success.

Advice for Aspiring Entrepreneurs

• Don't solely rely on advice from older generations; younger people have better current context.
• Pursue work that feels like play, where time becomes a blur and you genuinely enjoy the process.

AI in Biology: The Bitter Lesson Extended

• AI models trained on massive biological sequence data exhibit scaling laws similar to language models.
• These models can predict protein structure and function without explicit biological knowledge, aligning with the "bitter lesson" that general methods exploiting scale outperform hand-engineered features.
• Data scaling, particularly from metagenomic sources, is crucial for continued improvement, mirroring the "data wall" conversation in LLMs.
• Protein language models can rival specialized models like AlphaFold, especially in complex areas like antibody design, suggesting a shift towards generalizable AI approaches.
• Interpretability tools reveal that these models learn hierarchical biological concepts from sequences alone.

Selfplay for LLM Improvement

• Selfplay, inspired by AlphaZero, aims to auto-generate training tasks for LLMs to surpass human-level performance.
• Traditional selfplay can plateau due to generating overly complex or uninformative tasks.
• "Self-Guided Selfplay" (SGS) addresses this by grounding synthetic task generation in solvable problems and using a "guide" model to ensure task relevance and quality.
• While SGS shows improvement over baselines, it still faces challenges in reaching 100% solve rates, indicating ongoing research is needed.

Reducing Latency in Voice AI with Streaming RAG

• Voice AI requires low latency for natural conversation, which traditional RAG systems struggle to provide.
• Streaming RAG analyzes user speech in real-time to identify relevant information and trigger retrieval before the query is fully spoken.
• Approaches include fixed-interval streaming and adaptive triggering based on retrieval quality or semantic relevance.
• This technique can significantly reduce latency (e.g., 1.5 seconds on human data) with maintained accuracy.

Formal Verification and Verified Intelligence with Lean

• AI is making breakthroughs in solving formal math problems, including Olympiad and open mathematical challenges.
• Lean is a powerful language for formal mathematics and programming, enabling rigorous, machine-checked proofs.
• LLMs are being integrated with theorem provers like Lean for proof generation and verification, accelerating formalization.
• The focus is shifting towards "verifiable coding" and AI for science, requiring guaranteed correctness and reproducibility.
• Frameworks like "torchlean" allow defining and verifying neural networks within Lean, enabling certified robustness and formal analysis of AI systems.

Agentic Programming and "Token Maxing"

• Modern software development with AI agents is compared to real-time strategy games, requiring parallelization, constant adaptation, and high visibility.
• Practices include running workflows in the cloud, using portable development environments (like Git worktrees), and prioritizing parallel agent execution over token efficiency.
• Agents aim to complete tasks to pull requests, making assumptions and adapting to evolving specs, with human oversight for correction.
• A "macro by default, micro when it counts" strategy emphasizes spawning many agents and focusing human attention on high-level coordination and course correction.
• Building a comprehensive, linked knowledge base is crucial for agents to access business logic and improve future performance.
• Key principles include "satisficing" (doing enough, not perfectly), using audio/visual cues for agent monitoring, tracking tool calls (agentic "APM"), and maximizing resource utilization.

Company Overview & Mission

• Meesho is an e-commerce platform focused on providing the best value for money across categories.
• It was built for "mass India" with a mission to democratize internet commerce for a billion consumers and businesses.
• In the last 12 months, Meesho had 250 million consumers buying, with each buying about 10 times a year (2.5 billion orders).

Origin Story & Early Pivots

• Founded in 2015 by two friends from small towns who saw a gap between online shopping in big cities and its absence in their hometowns.
• Version 1: FashionNearMe (2015) - A local fashion commerce app for small businesses. Shut down after 3 months due to a crucial mistake: not speaking to consumers, resulting in a product worse than malls and traditional e-commerce.
• Version 2: Meesho (My Shop) - Focused on enabling small businesses to create an online shop on WhatsApp. This faced challenges in monetization as small businesses were unwilling to pay for software.

Product Market Fit & Growth (Social Commerce)

• Identified "resellers" (drop shippers) as power users who didn't have offline shops and actively used the platform to sell on WhatsApp.
• Launched Meesho Supply (later rebranded to Meesho) as a separate app to connect resellers with suppliers.
• Achieved significant product-market fit, doubling users every month for 10 months without marketing spend.
• This phase leveraged WhatsApp's distribution advantage due to lower data costs and text-based nature.
• At its peak, 10 million "Misho entrepreneurs" were selling to over 100 million people via WhatsApp groups.

Strategic Pivot to Direct-to-Consumer App

• In 2020, the decrease in data costs and the pandemic created a paradigm shift, threatening the reseller model.
• Decided to transition to a direct-to-consumer app to avoid losing customers to competitors. This was a risky move that required committing to the new direction, not experimenting.
• Launched the new app on July 5, 2021, and became the #1 shopping app on Android Play Store by July 7, 2021, a position maintained daily since.
• Within 5 months, user base grew from 10 million sellers to 100 million monthly active consumers.

CEO's Role in AI

• CEOs must be the Chief AI Officers, understanding technology bounds deeply.
• Focus on tasks only humans can do, as AI cannot replicate them.
• Rethink the company's core identity with AI integration.

The AI Paradigm Shift

• Early AI use treated LLMs as precious and expensive, leading to over-engineered systems ("Foxconn factory" approach).
• The true model is "agent loop with tools" (skills, tools, model).
• Electricity analogy: GPT-4.5 (December) was the invention of electricity; most are still using candles.

Securing AI Agents (Crab Trap)

• Focus on network layer security for AI agents, not just tool control.
• Crab Trap: An open-sourced HTTP proxy to analyze agent traffic, making it auditable.
• Uses another agent to analyze traffic and enforce policies, with an LLM acting as a judge.

AI Adoption and Productivity

• Token maxers see 10x productivity, average engineers 1x, and others use AI like Google search.
• AI enables "virtual employees" that can join meetings, take notes, etc.
• The "AI pill test": Do you default to AI for any problem?

Company Re-founding with AI

• Startups today should be built with AI as the core premise ("Why can't it just be me?").
• AI changes the fabric of a company, shifting focus from human execution to human wisdom and choice.
• Redesign processes end-to-end with AI, not just layering it onto old systems (e.g., KYC process).

Future of AI and Inference

• The future is "long inference" as AI adoption grows exponentially.
• Token costs will decrease, but usage will increase, making inference a major expense.
• Companies need to manage and analyze token spend for ROI.

Key Insights for Founders

• Minimize surface area; identify problems that can be solved with clear boundaries, potentially compressed by AI.
• Empathy and understanding unspoken customer needs (making the implicit explicit) are crucial, as models lack this.
• AI is a powerful tool, but human wisdom and choice remain the bottleneck.
• Embrace the "discontinuity" AI brings and rebuild from scratch if possible.

• They provide the final outcome, not just a co-pilot tool.
• Markets are trillions of dollars, unlocked by recent AI model advancements.

Picking the Right Market

• Must be a market you're passionate about for the long term.
• Ideal markets have:
• Low trust: Work is already outsourced, focus is on the outcome.
• Low judgment at task level: Most steps are automatable.
• High intelligence threshold: Overall work is complex, requiring AI + human expertise.
• Regulation can be good: Creates higher expectations and a moat.
• Examples: Tax, audit, insurance, mortgages, healthcare, logistics.
• Models should strengthen your service, not commoditize it.
• Avoid markets requiring on-site labor or physical equipment.
• Ensure humans are used for genuine judgment, not compensating for product gaps.

The Right Founding Team

• Build with people you know and have worked with.
• Key attributes:
• Domain fluency: Direct or learned experience in the industry.
• Model fluency: Understand frontier models and their future capabilities.
• Operational rigor: Focus on throughput, cycle times, SOPs.

Building the Actual Product

• The human is the interface; the product scales their work nonlinearly.
• Treat operations as the product: focus on bottlenecks, throughput, and cycle time.
• Variance is the existential problem: Inconsistent output destroys trust and causes churn.
• Humans in the loop must scale nonlinearly and enjoy using the software.

Sales and Customer Success

• Avoid the early demand trap: Cap initial pilot customers to avoid being overwhelmed.
• Sell outcomes, not seats or tokens. The pilot is the product.
• Learn from early pilots to identify unique AI leverage.
• Pricing competes with labor costs; consider per-unit or outcome-based pricing.
• Avoid cost-plus pricing and straight undercutting. Price on value.

The P&L (Profit and Loss)

• Revenue: Aim for smooth, predictable growth.
• Cost of Goods Sold (COGS): Obsess over model costs, hosting, and human costs. Be wary of negative margin pilots.
• AI Operating Leverage: The core bet is that increased product development lowers COGS and improves gross margins, aiming for software-like margins (50%+).
• Opex: Standard R&D, sales, and G&A costs.
• Operating Income: Judge on this metric; AI services can achieve higher margins than traditional firms.

Buying vs. Building

• Generally, building is better than buying an existing services business.
• Buying can be a trap due to legacy structures and expectations.
• The only strong reason to buy is to acquire regulatory necessity (e.g., licensing) quickly.

Recap

• AI services offer a generational opportunity.
• Focus on process as the product and product as the process.
• Avoid common traps to build a successful company.

• Prioritize building a product that customers are willing to pay for; revenue and customer commitment are key, not just having ideas.
• Builders and strong products are more crucial than sales in the AI space.
• "Burning the boats" (committing fully) forces innovation and makes things real. The cost of building is low, so start by building and selling to a small set of customers.

Inference Optimization

• Inference as a Capability: Inference speed directly correlates with peak intelligence, shifting its perception from a cost to a capability.
• Speculative Decoding: Uses a smaller, faster model to predict tokens, which are then verified by a larger, slower model.
• Speculative Speculative Decoding (SSD): Parallelizes drafting and verification, predicting verification outcomes to hide drafting latency and achieve significant speedups.
• Performance Gains: SSD enables sampling at high tokens per second (e.g., 300 tokens/sec for Llama 3 70B on 4 A100s).

Diffusion Models in Robotics

• Diffusion Model Predictive Control (DMPC): Uses diffusion models for multi-step action proposals and dynamics models to improve accuracy and simplify planning.
• Advantages: Reduces compounding errors, allows runtime adaptation to novel rewards and dynamics, and simplifies planning algorithms.
• Factorization Benefit: Separating action proposal and dynamics models allows adaptation to changing environment dynamics.

World Models

• Definition: Models that learn the dynamics of the world to predict how a system changes over time based on actions.
• Capabilities: Enable generating imagined outcomes, model-based control, and surprise quantification (uncertainty estimation).
• LAY World Model: A JEPPER model that uses an encoder-decoder architecture with a SIGG regularizer to ensure healthy, Gaussian-distributed latent embeddings, preventing representational collapse.
• Efficiency: Significantly faster than competition due to latent space operations and requires less VRAM.

Generalization in Deep Learning

• Scaling Laws & Generalization: Increasing model size generally improves generalization, but the mechanistic understanding is lacking.
• PAC-Bayes Framework: Explains generalization by bounding test loss with training loss and a compression term.
• Overparameterization & Compressibility: Larger models find more compressible solutions, reducing the compression term in PAC-Bayes bounds and improving generalization. Flat minima are more compressible.
• Benign Overfitting: Neural networks can fit random noise while generalizing on structured data due to flexible hypothesis spaces combined with soft inductive biases (e.g., favoring compressible solutions).

Data-Constrained Pre-training

• Problem: Compute for pre-training grows faster than available internet data, necessitating data-efficient methods.
• Standard Recipe Limitations: Training larger models with more epochs leads to overfitting and increased loss.
• Aggressive Regularization: Using significantly higher weight decay can improve performance in data-constrained settings, following power laws with a measurable asymptote.
• Ensembling: Ensembling smaller models proves highly data-efficient, offering better performance and lower asymptotes than a single large regularized model at the same parameter count.
• Joint Scaling: Combining regularization and ensembling offers the greatest potential for data efficiency, with projected double-limit asymptotes.
• Distillation: Both standard distillation and self-distillation can significantly reduce inference compute while retaining most of the data efficiency gains.
• Data Efficiency Wins: The joint scaling recipe shows a 5x data efficiency win over the standard recipe, with potential for even greater gains at larger scales.

Building an AI-Native Organization

• AI should be the foundational layer, not just a copilot.
• Record all artifacts to create a shared organizational brain.
• Frame AI as a tool for everyone to improve using collective skills.

YC's Internal AI Infrastructure

• Started with a project to give the finance team control over their software using English prompts instead of code.
• Initial success with LLMs for SQL queries, enabling non-technical users.
• Developed YC-specific agents and a tool registry, now with over 350 tools.
• Key tools include querying the YC database and reading model files.

The "Big Table" Concept

• Data needs to be denormalized and put into a format optimized for agent retrieval.
• This is analogous to the "big table" concept in data science, simplifying access and analysis.
• Tools like Gbrain facilitate this by normalizing data for agent understanding.

Multiplayer Agents and Organizational Transformation

• Current popular agents are single-player; the next frontier is multiplayer (team/organizational level).
• YC's infrastructure enables teams to use agents.
• Key primitives for organizational AI adoption: a common context layer (data warehouse) and an internal tool registry.

The Power of Tool Registries and Skills

• Tool registries turn generic agents into work-specific tools.
• YC's registry evolved from 20 to over 350 tools, enabling various functions.
• Skills are an abstraction layer over tools, evolving to self-improving loops and autonomous systems.
• An example is a skill to generate two-sentence company descriptions, which improved over time through agent learning.

Building Super Intelligence

• Super intelligence arises from composing everything an organization does with AI.
• It's about improving every task, not just a few.
• Startups are ideal for this due to high-trust, egalitarian environments.

AI as an Empowerment Tool

• AI should empower humans, not replace them.
• It eliminates drudgery and enables individuals to do more.
• This is a continuation of the trend of individual empowerment seen with PCs and the internet.

Decentralization vs. Centralization of AI

• There's a choice between centralized AI (controlled by a few companies) and decentralized AI (personal, controllable).
• The "Horseless Carriage" essay critiques AI features tacked onto existing software rather than AI as the foundation.
• The ideal is agent-wrapping deterministic tools, not the other way around.
• Personal computers and the Homebrew Computer Club represent the "Apple 1 moment" for AI, focusing on individual control and experimentation.

The Future of Interfaces and Software

• Chat is a powerful interface due to its closeness to human language and thought expression.
• The future of software is "just-in-time," dynamically built by agents.
• Minimalist, self-extending software (like Pi and OpenClaw) is key.

Organizational Choices for AI

• Companies must choose to be open and trust-based to leverage AI effectively.
• Default company structures are often command-and-control.
• Providing computing access and encouraging agent use empowers all employees.

Introduction to Incorruptible

• Companies often lose what made them special and founders lose control, leading to a need for tools to protect their creations.
• The focus is shifting from "0 to 1" (Lean Startup) to "1 to 100" (long-term sustainability).

The Dangers of Success and "Best Practices"

• Success makes companies valuable targets for takeover or exploitation.
• "Best practices" like shareholder primacy, originating in the 1980s, are value-destroying and not a natural law.
• Delaware C-Corps have a legal requirement to relentlessly pursue profit, which can lead to founder removal.

Case Studies: Founders vs. The System

• The "professor" founder of an AI/bioscience company faced pressure from investors and lacked a framework to resist unethical demands.
• Jeff Lawson (Twilio) was ousted after his dual-class share protections expired, despite company success.
• Edwin Land (Polaroid) was fired, leading to a decline in innovation.
• Saul Price, founder of FedMart and Price Club (leading to Costco), was ousted despite prioritizing customers. His company failed, but Price Club eventually merged to form Costco, which still embodies his customer-first ethos.

Building Incorruptible Companies: Ethos + Integrity

• The formula for an incorruptible company is Ethos (higher principle) + Integrity (structural protection).
• Companies need structural integrity to protect their core mission from temptation and pressure.
• Challenging the "normative consensus" of best practices is the first step.

Structural Solutions for Longevity

• Public Benefit Corporations (PBCs) are an easy and essential choice for founders, restoring purposeful incorporation.
• Industrial Foundation Structures (like Novo Nordisk's) and Perpetual Purpose Trusts (like Anthropic's) create a "governance fortress" to protect the mission.
• These structures involve outside trustees who appoint directors, ensuring alignment with the company's purpose over short-term profit.
• Companies with these structures are significantly more likely to achieve long-term survival (e.g., 6x more likely to reach year 50).

The Role of Founders and Investors

• Founders must understand their governing documents and be savvy about governance.
• Investors and lawyers often fail to inform founders about alternative structures, adhering to a "business monoculture."
• VC fund structures (typically 10-year terms) create pressure for quick exits, conflicting with long-term company building.
• While founder control (e.g., dual-class shares) is better than investor control, it's not invincible and can lead to hubris. Backup structures are crucial.

Counterintuitive Benefits of Mission Control

• Companies with strong mission-driven structures, like Anthropic, gain a significant talent advantage as people want to work for "the good guys."
• This structural strength allows companies to stand up for their values, leading to unexpected positive outcomes (e.g., Claude's rise after declining a controversial contract).

Company Organization Shift

• Traditional companies are like Roman legions with human information conduits; AI breaks this hierarchy.
• AI's true value is reimagining company structure, not just boosting productivity.
• Companies can be structured as recursive, self-improving AI loops that operate even during sleep.

The Self-Improving AI Loop

• Sensor Layer: Collects data (customer emails, support tickets, code changes).
• Policy Layer: Defines rules and permissions for AI actions.
• Tool Layer: AI-executable functions (query database, check calendar).
• Quality Gate: Ensures checks, filters, and human review for high-risk actions.
• Learning Mechanism: System learns from real-world interactions and refines processes.
• Full automation of this loop leads to continuous self-improvement.

Transforming Business Functions with AI Loops

• Customer Introductions: AI agents query databases, use RAG to suggest relevant contacts.
• Monitoring & Improvement: An agent analyzes query success/failure, identifies needs for new tools or data views, and automatically updates code.
• Product Analytics: AI identifies sales funnel friction, researches best practices, A/B tests, and deploys improvements.
• Customer Service: AI triages suggestions, aligns with roadmap, writes and deploys code for new features.

Implications for the Future of Work

• Burn Tokens, Not Headcount: Companies will be constrained by AI token usage, not employee numbers.
• Middle Management is Obsolete: AI can handle coordination, simplifying organizational structure.
• Focus on Builders/Operators (ICs): Individuals directly responsible for tasks are key; no committees.

Building an AI-Legible Company

• Record Everything: All interactions (emails, Slack, office hours) must be recorded to be legible to AI.
• Diorize & Synthesize: Raw data needs to be aggregated and synthesized into understandable formats for AI context.
• Self-Improving Artifacts: Create outputs (like user manuals) that AI can continuously update and improve.
• Ephemeral Software: Treat generated software dashboards and workflows as disposable; focus on the underlying data and business context.

The Role of Humans

• Humans interface with the real world at the edges of the AI "company brain."
• Humans are crucial for novel situations, ethical considerations, high-stakes moments, and complex sales conversations.

Founding Zepto

• Started by Aadit Palicha and Keville at age 17, inspired by Silicon Valley builders.
• Took a year off from college during COVID-19 to work on a project.
• Began with a WhatsApp group to deliver groceries for neighbors in Mumbai.
• Initially named the app Kiranakart.

The Stanford Decision

• Palicha turned down an offer to study at Stanford to pursue Zepto.
• Decided to take a year off to test the market before fully committing.
• Waited until they achieved significant product-market fit (around 10,000 orders/day) and investor interest before quitting college.

Pivoting to Zepto (from Kiranakart)

• Original model involved delivering from existing local stores, lacking control over customer experience.
• Co-founder's apartment served as the first "dark store" or mini-warehouse.
• Observed a 3-4x increase in volume in the neighborhood with the dark store model.
• Realized the need to control the customer experience, leading to the mini-warehouse strategy.

Customer-Centric Approach and 10-Minute Delivery

• Silicon Valley offers the best peers and a larger talent pool, leading to more valuable serendipitous meetings.
• Faster decision-making, especially from investors, is a key advantage due to increased competition.
• Leaving for Silicon Valley can increase respect back home and make local investors more interested.
• The biggest advantage is seeing successful people and realizing you can achieve similar success with hard work, setting a higher standard.
• Silicon Valley fosters a "pay it forward" culture where people help each other for no immediate reason.

Making Stockholm a Startup Hub

• The best way for Sweden/Stockholm to thrive is for founders to go to Silicon Valley for a bit and then return.
• Returning founders improve the local startup ecosystem, potentially bring back investment, and import Silicon Valley's startup culture.
• Y Combinator (YC) is an optimal way to experience Silicon Valley, concentrating its unique advantages.
• While returning startups may not achieve the same valuations as those staying in SV, they still perform well and can become billionaires.
• Stockholm has the potential to become the Silicon Valley of Europe, needing only founders who want to live there and achieve critical mass.

Gary Tan's AI-Powered Building

• Gary Tan, CEO of Y Combinator, returned to building software after a hiatus, shipping hundreds of thousands of lines of code and creating popular open-source projects.
• He achieved this by leveraging AI tools, enabling him to do the work of approximately 400 engineers.

Token Maxxing Philosophy

• Tan emphasizes "token maxxing" – using AI models extensively, even if costly, to achieve maximum utility and completeness.
• This is compared to the necessity of living in expensive areas like San Francisco for startup founders to gain an advantage.

Gary's List Project

• Started with Gary's List, a project to mobilize support for causes, particularly in California education (e.g., enabling middle schoolers to take algebra).
• The website functions as a blogging platform but also performs investigative journalism by ingesting and analyzing vast amounts of information.
• It can produce detailed reports and quotables comparable to human investigative journalists, at a fraction of the cost ($5-10 in API calls).

GStack and Agentic Engineering

• Developed GStack, a suite of AI "skills" or tools, born from Tan's repetitive tasks and need for automation.
• Key skills include "CEO plan" (metaprompting inspired by Brian Chesky's 10-star experience concept) and "Plan/Review" for architecture, code quality, and testing.
• Utilized ASCII diagrams for data flow visualization to improve AI model understanding and reduce errors.
• Advocates for focusing AI prompts on "markdown" (instructions) and using code for deterministic tasks.

AI Workflow and Tools

• Tan's daily workflow involves queuing tasks in a "conductor instance," using skills like CEO and a highly tested "plan mode."
• He developed a custom Playwright wrapper for faster QA testing, automating tasks that previously required manual checks.
• GStack includes roles like CEO, designer, developer experience, and a developer.
• He leverages both Claude Code (for ADHD CEO tasks) and Codex (for a "200 IQ CTO") within GStack.
• The system integrates with code repos, finds problems, and feeds feedback to Claude Code for resolution.
• The "Browse" feature acts as a CLI for testing UI and data mutations.

Control and the Future of AI

• Tan believes in owning your AI tools rather than being controlled by them, advocating for personal AI agents.
• He compares the current AI development to the Homebrew Computer Club era, a foundational moment for personal computing.
• The future will offer a choice between personal, controlled AI and corporate-controlled AI feeds.
• He stresses the importance of writing one's own prompts to ensure AI serves individual needs.

Lines of Code and Productivity

• Tan controversially discussed his AI-assisted output of hundreds of thousands of lines of code, later refining it to 400x his previous rate.
• He argues that AI directs the code generation, unlike humans who might pad lines of code.
• The average professional software engineer produces far fewer lines of production-ready code daily than often assumed.

Early Days & Problem Identification

• Harshil was a coder with no initial interest in finance or startups.
• He encountered the difficulty of accepting online payments in India while building a side project.
• Noticed that it was easier to accept cash than digital payments, which contradicted the purpose of technology.
• Realized this was a significant, unsolved problem affecting many startups.

Pivoting Strategy & GTM

• Initially planned to target educational institutes for fee payments but found low customer interest.
• Pivoted to serving startups, who were eager for digital payment solutions.
• This pivot was a crucial decision that led to early traction.

The Regulatory Moat

• Razorpay faced a year-long wait for approvals and licenses before its first live transaction, a significant "gestation period" for a tech business.
• The complexity of regulations created a moat, deterring competitors due to the high barrier to entry.
• Regulations, though challenging, are fair and apply equally to all, fostering long-term trust and reliability.

Conviction & Customer Focus

• Despite monthly doubts, the conviction came from direct customer feedback: founders confirmed the problem and the lack of solutions.
• "Make something people want" was the guiding principle; customer validation provided energy.
• Customer love after onboarding reinforced the belief in solving a critical problem.

Navigating Crises: The Bank Pull-Out

• A bank partner suddenly stopped supporting Razorpay just before Demo Day, shutting down payments for 50+ live merchants.
• The team's fundamental principle was to maintain trust through transparent, human communication.
• They personally called every affected customer, explaining the situation and their actions, even enduring abuse.
• This crisis solidified the importance of human touchpoints and trust in B2B relationships, especially in finance.

Long-Term Vision & Acquisition Offers

• Received early acquisition offers from global payment companies.
• Believed these companies underestimated India's complexity and growth potential.
• Razorpay's vision required a long-term perspective and significant investment that global players struggled to grasp.
• Chose to remain independent to achieve their vision for India.

Capital Efficiency & B2B Logic

• Grew 40x between 2017-2020 with remarkable capital efficiency.
• Investor concern: Razorpay's interest income from fixed deposits exceeded its burn, making it profitable.
• B2B businesses are logical: value is exchanged for payment; excessive burning is unnecessary.
• Focused on adding value consistently, knowing customers would leave if value decreased.

Early UPI Bet

• Became the first payment gateway to go live on UPI in September 2016, before major banks integrated.
• This early bet, made when UPI was doubted, positioned them to capture market share during demonetization.
• Leveraged being small to take calculated risks that larger, slower competitors couldn't.

Embracing AI & Reinvention

• AI is a fundamental shift requiring recalibration and leadership focus.
• AI tools allow founders to return to "building mode," away from pure management.
• Razorpay reinvented its entire platform based on how they would build it today with AI.
• The strategy is to act like a startup, proactively adopting AI changes rather than reacting.
• AI will reduce build time, making execution speed the primary differentiator.

Founder Evolution & Advice

• Learned the critical difference between "manager mode" and "founder mode."
• Founders must remain deeply involved in core product vision and direction.
• No one will care about the company as much as the founder; this never changes.
• Advice for aspiring founders: Find a problem you can commit 10 years to solving; AI makes building easier but doesn't change the core requirement of deep problem connection and sustained effort.

Introduction to Recursion in AI

• Recursion is proposed as the next scaling law in AI, improving reasoning performance at inference time rather than just increasing model size.
• Hierarchical Reasoning Models (HRM) and Tiny Recursive Models (TRM) are highlighted as key papers demonstrating this approach.

Limitations of Traditional RNNs and LLMs

• RNNs suffered from "back prop through time," leading to vanishing/exploding gradients and error accumulation, especially with long contexts.
• LLMs, while efficient at training time with parallel processing, lack inherent reasoning and compression in the time direction, requiring the entire context for each step.
• LLMs struggle with tasks requiring sequential reasoning steps (like sorting) that exceed their fixed number of layers.

Hierarchical Reasoning Models (HRM)

• HRM uses multiple levels of recursion inspired by the brain's different operating frequencies.
• It employs a "deep equilibrium learning" (DEQ) method, specifically truncated backpropagation through time (T-BPTT), to avoid backpropagating through all recursion steps.
• The key innovation is the "outer refinement loop," which scales and improves performance significantly.
• HRM achieved state-of-the-art results on ARC Prize with a small parameter count (27 million) and no pre-training.

Tiny Recursive Models (TRM)

• TRM simplifies HRM by collapsing the hierarchical levels into a single network with shared weights.
• It further refines the backpropagation by backpropagating through only one full latent recursion step.
• TRM achieves even better performance (87% on ARC Prize 1) with a smaller model (7 million parameters) compared to HRM.
• TRM demonstrates that recursion can provide compute depth without parameter depth.

Broader Implications and Future Directions

• Recursion is crucial and not going away; adding it to models shows significant benefits.
• Truncated backpropagation through time (T-BPTT) and outer refinement loops are powerful ideas to explore further.
• Combining the efficiency of recursive models with the scale of giant LLMs could lead to breakthroughs.
• Future research could focus on making recursive models more general-purpose and integrating them into latent spaces for enhanced reasoning.

• Key components for AGI likely include large-scale pre-training, RLHF, and chain-of-thought, which are believed to be part of the final architecture.
• Unsolved areas crucial for AGI are continual learning, long-term reasoning, and aspects of memory.
• It's possible current techniques can scale to solve these, or one or two major breakthroughs are still needed.

Continual Learning and Memory

• The brain handles continual learning and memory consolidation gracefully, a process studied by Hassabis during his PhD.
• DeepMind's early Atari program DQN used experience replay, inspired by neuroscience.
• Current context window usage feels like "duct tape," and even large windows have a cost for relevant information retrieval.
• Processing live video requires significantly more than a million tokens for extended context.

Agents and Reinforcement Learning

• Agents are seen as the path to AGI, requiring active systems to solve problems.
• DeepMind's early work on AlphaGo and other games involved agent systems designed for goal accomplishment and active decision-making.
• Many current foundation model techniques, like chain-of-thought, have roots in AlphaGo's pioneering work.
• Reinforcement learning and search techniques from AlphaGo and AlphaZero are considered highly relevant today.
• Agents are still in their early stages; full adoption into workflows is just beginning.

Model Efficiency and Open Source

• A core strength of Google DeepMind is distilling frontier model capabilities into smaller, efficient "flash" models.
• This is crucial for serving billions of users across various Google products with speed and low latency.
• There's no current known informational limit to how smart smaller models can become through distillation.
• Google DeepMind is a proponent of open source, exemplified by the release of Gemma models, which have seen significant downloads.
• Open models are strategically important for edge devices like Android and robotics due to their inherent vulnerability.

Multimodality and Scientific Breakthroughs

• Gemini was built to be multimodal from the start, offering advantages for world modeling and robotics.
• Multimodal capabilities are essential for AI in the real world, understanding physical context and intuitive physics.
