The New Physics of Business — Garry Tan, Y Combinator

Garry Tan, President of Y Combinator, discusses how the rise of AI-native companies is revolutionizing organizational productivity, allowing lean teams to operate at a scale previously requiring hundreds or thousands of employees (0:52-1:07). Key Takeaways: The 400x Leverage: Tan reports a massive increase in output (approximately 400x) by shifting from writing individual lines of code to managing AI agents (2:32-2:35). Wiring the Work: He emphasizes that founders should treat AI not as a simple autocomplete tool, but as a workforce (3:58). He explains that core organizational components—like roles, processes, and performance reviews—can now be encoded as markdown-based skill files (4:31-5:32). The AI-Native Organization: Successful startups at Y Combinator are building "company brains" (like his own project, GBrain), which act as a library and librarian, ensuring that agents have access to the right context at the right time (12:54-13:30). Discipline of Execution: He advises never to perform "one-off" work. Instead, every task should be refined into a reusable skill file to prevent the company from "waking up with amnesia" each day (15:30-16:40). The New Physics of Business: Tan argues that modern companies can achieve unprecedented revenue-per-head ratios by building on this new infrastructure, effectively "boiling the ocean" by automating formerly impossible tasks (6:40-7:15; 19:55-20:00).

(3:06) "When you sit down with Claude Code or Cursor, you're not writing software. You're hiring, training, and managing a workforce made of markdown." (5:58) "The organization that captures what it learns like this gets smarter every single day. The one that doesn't wakes up every morning with amnesia." (16:26) "Abundance is not a policy paper. It is shipped software." (18:56) "Every archive too big to read, every data set too gnarly to clean, every ocean you were told not to boil. We can boil the ocean now." (19:55)
