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).

• India has the best technical talent to build the world's largest AI companies.
• Success in AI is about understanding the technology 10x better than others, an area where India excels.
• Founders can now build global companies from India without needing to be in Silicon Valley or having prior US market connections.
• 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.

• 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.

• Unlike Webflow, which focused on a specific persona (freelance web designers), Ploy aims to serve tens of millions of people.
• Ploy leverages AI to automate tasks that previously required manual coding and extensive infrastructure setup, allowing for faster and more comprehensive output.
• 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.

Core Philosophy & Future with AI

• Company value: "Be problem first. Be very rigid with your problem and be very flexible with your solution."
• Believes AI will revolutionize e-commerce.
• Developing AI innovations like the voice agent "Wani" to remove barriers to entry for consumers, especially in rural areas.

• Advice to aspiring entrepreneurs: Identify gaps, leverage new technologies like AI, and remain customer-obsessed.

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.

What is an AI-Native Services Company?

• Companies rebuilding traditional services (tax, insurance, law) from scratch with AI doing most of the work.
• 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.

Company Overview

• GigaML builds AI agents for customer support, working with major companies in crypto, telecom, and other sectors.
• Their AI agents aim for high deflection rates (60-70%, targeting 90-95%), providing a more human-like and efficient customer experience, eliminating hold times.

Founding Story & Y Combinator

• Founders are IIT engineers who received a $550K job offer from a quant firm.
• They applied to Y Combinator with an edtech idea, but were advised by Hajj to pivot to something else, leveraging their LLM research experience.
• This pivot was crucial, and YC's belief in their engineering talent led to the company's inception.

Product Evolution

• Initially focused on fine-tuning LLMs to reduce costs, open-sourcing models and gaining traction on Hugging Face.
• Realized customer support and coding were the two fastest-growing use cases from their customers.
• Pivoted to focus on AI for customer support, driven by customer needs, starting with Zeptro as their first customer.

Market & Competition

• Won a significant contract with DoorDash, competing against a much larger, well-funded company, proving the value of a great product over sales teams.
• DoorDash's trust was partly due to both being YC companies, fostering inherent trust.
• Believes in building a great product and focusing on customer willingness to pay, rather than solely on market size or competition.

AI Agents & Future Vision

• AI agents fundamentally boil down to iterating on policies (e.g., markdown files) to improve business KPIs.
• The next major product is an "AI Forward Deployed Engineer" to automate enterprise AI adoption, tackling the bottleneck of human configuration.
• Emphasizes automating internal processes, using AI tools for sales analysis and development, reducing engineering team size by up to 7x.

Advice for Aspiring Founders

• Don't be afraid to reject high-paying jobs to pursue a startup; focus on potential and pushing boundaries.
• 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.

• 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.

• The pursuit of "Minimum Viable Quality Product" (MVQP) balances progress with maintaining user trust, especially when incorporating new technologies like AI.

The GPT Moment for Robotics

• The equation for starting a robotics business has changed due to decreasing upfront costs.
• The mission is to build a model that can control any robot for any physically capable task at a high performance level.
• The approach is to build a strong base model with common sense knowledge, then use a mixed autonomy system that improves over time with real-world exposure.

Why Robotics is Difficult and Recent Breakthroughs

• Robotics has three pillars: semantics (language models help here), planning, and real-time control in dynamic environments.
• Seikhan demonstrated using language model common sense knowledge in robotics, reducing the need for robot-specific data.
• POMoE and RT2 (Robotic Transformer 2) showed that adapting powerful vision-language models with robotic data allows knowledge transfer to low-level actions, enabling tasks with unseen objects or concepts (e.g., "move the coke can to Taylor Swift").
• These initial models were single-embodiment (worked for specific robots).

Scaling and Cross-Embodiment

• The insight is that data from multiple robots can teach a more abstract notion of robot control, leading to better generalization.
• Open Cross Embodiment and Robotic Transformer X showed scaling laws for robotics by training across multiple hardware platforms, a first in the field.
• A generalist model trained on data from 10 different robot platforms performed 50% better than specialist models optimized for individual platforms.
• OpenX was a large collaboration within the robotics community.

The Data Problem and Its Scale

• The data problem in robotics has two parts: data generation and data capture.
• There's a lack of an "internet of robotic data," requiring operational effort for collection.
• Solving robotics could contribute significantly to GDP, justifying investment in data collection.
• The approach focuses on cross-embodiment to easily consume data from diverse robot sources.
• No two robot platforms are the same, and platforms drift over time, making multi-robot data ingestion more robust than optimizing for a single, changing platform.

Emergent Properties and Current State

• Emergent properties are being seen in large robotic models, allowing for zero-shot task performance that previously required extensive data collection.
• Tasks requiring precision, reasoning with multiple objects, and deformable objects (like laundry folding) are being tackled.
• Current state allows for scaling robot deployment if tasks can tolerate mistakes and a mixed-autonomy system (human oversight) is feasible.
• Examples include folding laundry in a real laundromat (collaboration with Weave) and picking/placing items in pouches for shipping (collaboration with Ultra) in real e-commerce warehouses.
• These demonstrations show autonomy at scale, ready for deployment.

Technical Insights: Cloud-Based Inference

• A surprising insight is that most robot evaluations are cloud-hosted, even for complex demos.
• This is enabled by tightly coupling system, hardware, and model development.
• Real-time inference is achieved by burying it within the robot's control loop, querying the cloud API as needed, rather than waiting for actions to complete.
• Algorithmic improvements like "real-time chunking" and pre-computation ensure smooth transitions between predicted action chunks.
• This approach simplifies robot hardware, reducing the need for powerful on-board compute and expensive hardware that quickly becomes obsolete.
• The cloud-based approach allows for decoupling hardware control from semantics and planning.
• The pace of progress has been faster than expected, with real deployment and scaling being serious considerations two years into the company's life.

Starting a Robotics Company Today

• Robotics was historically vertically integrated with high barriers to entry.
• Physical Intelligence aims to provide an AI foundation for others to build upon, enabling faster autonomy onboarding.
• The new playbook for a vertical robotics company: understand existing workflows, identify opportunities for maximum impact, be scrappy with hardware and data collection (models compensate for inaccuracies), and implement mixed-autonomy systems to reach economic break-even for scaling.
• Upfront costs are significantly lower, focusing on use case identification and data collection rather than proprietary autonomy stacks.
• This allows companies to differentiate themselves on the components that matter most.

The Future: A Cambrian Explosion

• There is a strong belief in a "Cambrian explosion" of robotics companies across many verticals due to lower costs and accessibility.
• It no longer requires decades of robotics experience to start; scrappiness and speed are key.
• The focus shifts from building vertically integrated systems to identifying use cases and leveraging foundational models.
• The promise is to enable a massive increase in robotic applications beyond traditional "dirty and dangerous" industrial tasks.
• Physical Intelligence aims to enable this explosion by providing foundational models, publishing research, and open-sourcing models (PI Zero, PIO5 are the same as internal models).

Enabling the Future and Company Building

• The infrastructure for large-scale, general-purpose robotics (data collection, management, annotation, evaluation) was largely missing, prompting Physical Intelligence to build much of its own software.
• There's an opportunity for services that support robotics companies (e.g., remote teleoperation, data collection, annotation).
• A tight, collaborative loop in model development (data collection -> training -> evaluation -> improvement) is crucial.
• An "automated robotic research scientist" is a desired future development to bottleneck progress.
• Current language models can assist with simple failure modes by providing recommendations based on textual descriptions of failures.
• A fundamental understanding of the physical world, which is missing in current foundation models, is needed for more advanced automation.
• Using cloud-based inference with large models has shown significant improvements in compute utilization (e.g., a prototype "pre-training on call" improved utilization by 50%).
• The company's mission is to create this Cambrian explosion by focusing on the model as the bottleneck and enabling others to build on their work.
• Success is defined not just by their own models on their robots, but by their models performing useful tasks on *other people's robots*.
• The founding team, many from Google's robotics team, enjoy working together and believe their combined strengths increase the chances of success.

Company Genesis and Core Technology

• They were driven by a desire to solve the inefficiencies and limitations they observed in fraud detection at scale.
• Landing their first enterprise customer, IA (specifically Ask Media Group), took eight months and involved convincing them to use LLMs for marketing content review, a task previously done manually by a large team.
• The company started building with LLMs just before ChatGPT's widespread adoption.

Resilience & Vision

• Karine experienced a severe accident where she was hit by a truck, breaking her spine and leg, highlighting the founder's critical role and the need to scale processes beyond a single individual.
• Despite the setback, the founders remained committed to their mission, driven by a sense of duty to improve the industry with their expertise.
• Their strong initial hypothesis about the problem and solution has guided their development, rather than pivoting frequently.
• They believe their deep understanding of the problem and commitment to solving it resonate with customers.

Introduction to NDIA and Program Synthesis

• NDIA is a new AGI research lab aiming to build a new branch of machine learning, an alternative to deep learning, focusing on program synthesis.
• The goal is to create a new learning substrate that is much closer to optimal than current parametric deep learning models.
• This approach involves building extremely concise symbolic models of data, contrasting with deep learning's reliance on fitting parameters of complex curves.
• NDIA proposes "symbolic descent" as the equivalent of gradient descent in this symbolic space.

Limitations of Current AI and the Case for Alternatives

• The current industry focus on scaling LLMs, while productive, is seen as potentially counterproductive due to everyone working on the same thing.
• François Chollet believes the current LLM stack may not be the foundation for AI in 50 years and aims to leapfrog towards optimal AI.
• He acknowledges that such ambitious projects have a low chance of success but are worth pursuing if successful.
• The success of coding agents is attributed to code providing a verifiable reward signal, enabling automation in domains with formal verification.
• Domains like English language composition or law are harder to automate due to a lack of natural formal verifiability, leading to slower progress with current LLM stacks.

Defining and Measuring Intelligence: The ARC AGI Benchmark

• Chollet's definition of AGI is a system that can approach any new problem or domain, model it, and become competent with human-level efficiency (data and compute).
• He believes current technology can already automate any domain with verifiable rewards, but achieving human-level learning efficiency across arbitrary tasks requires a different approach.
• The ARC AGI benchmark was created to capture the idea of intelligence as skill acquisition efficiency, inspired by ImageNet for reasoning.
• ARC V1 and V2 focused on producing causal models from given data, while V3 measures "agentic intelligence."
• ARC V3 requires an agent to explore an interactive environment (like a mini video game) without instructions, measuring exploration efficiency, goal setting, planning, and execution.
• V3 aims to measure fluid intelligence, the ability to efficiently explore and model new environments, matching human efficiency.
• V3 is designed to be more resistant to "harness" strategies used to saturate V2, using a private set of environments with novel concepts.

NDIA's Approach and Future Vision

• NDIA's approach involves deep learning-guided program search, using deep learning to guide exploration in a symbolic search space.
• Chollet predicts that AGI, when achieved, will be a small codebase (megabytes), distinct from a large knowledge base.
• He believes that retrospectively, AGI might be found to be a codebase under 10,000 lines of code, achievable with past computing resources.
• NDIA aims to remove humans from the improvement loop for self-improving, compounding systems.
• The NDIA approach is described as "science incarnate," recreating the scientific method algorithmically through symbolic compression.
• Chollet believes human intelligence is messy but its underlying principles can be reimplemented more efficiently.
• The development of NDIA started with a symbolic learning vision, focusing on replacing parameter curves with shortest symbolic models.

The Evolution of ARC AGI and Future Prospects

• ARC V1 was initially difficult for LLMs, showing that scaling alone wasn't enough for fluid intelligence.
• The emergence of reasoning models led to significant performance improvements on ARC V1, signaling new capabilities.
• ARC V2 was saturated by large-scale targeting using reinforcement learning loops and "harnesses" to generate and solve tasks, demonstrating a new post-training paradigm.
• This saturation indicates models becoming more useful in specific domains through better training and verifiable reward signals, not necessarily "smarter."
• ARC V3 moves beyond modeling static data to testing agentic intelligence in interactive environments.
• Future ARC benchmarks (V4, V5) will focus on continual learning, curriculum learning, and invention.
• Chollet predicts AGI might be achieved around the early 2030s.

Advice for Aspiring AI Researchers and Developers

• There is room for startups exploring alternative AI approaches beyond LLMs, such as scaled-up genetic algorithms or alternative architectures.
• Researching older, less-invested-in approaches from the 70s and 80s is recommended.
• Promising approaches should demonstrate scalability and allow for improvement without constant human intervention (recursive self-improvement or decoupling from human effort).
• For open-source projects, focus on a simple, intuitive API, usability, informative documentation, and community building.
• Hiring enthusiastic users ("fans") can be beneficial for building successful projects.
• AI progress should be viewed as empowerment, with expertise in a domain allowing individuals to leverage AI tools for their benefit.

• Founders should develop an intuitive understanding of agent capabilities and limitations, and build tools that cater to their natural inclinations.

The video features Boris Cherny, an engineer at Anthropic, discussing the development and philosophy behind Claude Code, an AI coding assistant.

Origin and Philosophy

• Accidental Beginning: Claude Code started as a simple terminal chat app built by Boris to learn Anthropic's API, not as a planned product.
• Building for the Future: Anthropic's strategy is to build for the model six months ahead, focusing on areas where current models are weak but expected to improve.
• Latent Demand: Key features and products, like ClaudeMD, emerged from observing how users were already trying to achieve tasks, demonstrating "latent demand."
• The "Bitter Lesson": Cherny emphasizes "never bet against the model," advocating for waiting for model improvements rather than building excessive "scaffolding" that will quickly become obsolete.

Development and Evolution

• Terminal-First Approach: The initial choice of a terminal interface was due to its simplicity and speed of development, avoiding the need for a complex UI.
• Tool Use Discovery: A pivotal moment was realizing the model's strong inclination to use tools, even for tasks like identifying music.
• Iterative Rewriting: The codebase for Claude Code is constantly rewritten, with significant portions being less than six months old, reflecting rapid model advancements.
• User Feedback Driven: Features like "plan mode" and verbose output options were direct responses to user feedback and observed usage patterns.
• Adapting to Model Improvements: The shift from requiring manual debugging of model output to summarizing tool usage reflects the increasing reliability of newer models.

Key Features and Concepts

• ClaudeMD: A mechanism for users to provide custom instructions and context to Claude Code, with an emphasis on keeping it concise and up-to-date.
• Plan Mode: A feature that allows users to outline a plan for the model before it starts coding, reducing the risk of it going in the wrong direction. Cherny suggests this may become obsolete as models improve.
• Agent Topologies: The exploration of how multiple agents can collaborate, using concepts like "uncorrelated context windows" for complex tasks.
• Swarm Development: The successful use of a "swarm" of agents to build features like the plugins feature over a weekend with minimal human intervention.
• Sub-Agents: The use of recursive Claude Code instances ("mama quad") to handle specific tasks, often prompted by the main agent.

Impact and Future

• Massive Productivity Gains: Claude Code has reportedly led to significant increases in engineer productivity at Anthropic, with internal metrics showing substantial growth in output.
• Coding Solved: Cherny predicts that coding will become generally "solved" for everyone, potentially leading to the evolution of roles like "software engineer" into more general "builder" or "product manager" titles.
• Beyond Coding: The future may see models capable of recursively self-improving (ASL4) or being misused for dangerous purposes, highlighting the importance of AI safety.
• Expanding Form Factors: While originating in the terminal, Claude Code is now integrated into various interfaces like desktop apps, web, Slack, and IDE extensions, with continuous experimentation in UI/UX.
• Advice for Builders: Focus on latent demand, build for future models, and embrace the "bitter lesson" of general model improvement over specific scaffolding.
