Garry Tan: Own Your Intelligence

Video summary

Garry Tan says personal AGI can make one founder 400x more productive—and argues your AI skills should stay in your own repo.

At Startup School 2026, Y Combinator CEO Garry Tan uses Baruch Spinoza’s excommunication and refusal to trade intellectual freedom for a salary to frame his case for “personal AGI.” Rather than rent a generic chatbot, he says, build an agent around a library of your own context, reusable Markdown skill files, and tools you control. Tan estimates AI agents have raised his coding output about 400x since 2013, with a conservative floor of 8x, and points to YC companies reaching $15 million in annualized revenue with 15 employees. He describes a 220,000-page personal knowledge system and gives five steps to start one, while warning that workers must own their skills before employers turn them into company assets. His closing example is a father’s 80,000-file research library for his son’s rare epilepsy: one person, Tan argues, can now build what once required a team and permission.
