Paul Graham says formidable founders—not a specific idea—will build the next trillion-dollar company, while AI changes little about startups.
At YC’s 21st year and 47th batch, Paul Graham says startups still face the same core challenges, but today’s founders are pursuing more ambitious ideas, from cancer research to intercontinental cargo rockets. He describes ambition as what carries founders through grueling obstacles, while day-to-day work is driven less by dreams of wealth than by fear of failure. A formidable founder, he says, is someone who gets what they want. Graham recalls OpenAI changing how he searches for information and says AI arrived as a flawed, human-like generalist rather than a perfect system that gradually gained abilities. He argues startups can still begin with little money, shipping speed remains a key predictor of success, and AI can bring bills of tens of thousands of dollars a day. YC began as an angel firm and summer-job alternative; its batch model and core startup challenges have changed little. The next trillion-dollar company, he concludes, will come from formidable founders.
