Patrick Collison says Stripe’s new-business starts are nearly 2x year over year, making this a better time than ever to found a company.
At Startup School 2026, Stripe co-founder Patrick Collison told YC’s Harj Taggar that students should keep building knowledge: mental “L1 cache” is faster than asking AI, and he still prefers writing his own messages. He dropped out of MIT twice, but says leaving is reversible and the urgency he felt was unnecessary. Stripe began after the brothers attended Startup School in Berkeley in 2009 and got sushi in Potrero Hill; they expected it “probably won’t be that hard,” yet took almost two years to launch publicly. Early production users shaped the product while the founders built payment security and banking infrastructure. Collison suggests AI may favor more ambitious, divergent startup ideas over the traditional lean-startup niche hunt, and urges founders to consider whether they would enjoy succeeding. Stripe data shows new business starts are nearly 2x year over year, median businesses are doing better, and time to revenue is falling. He attributes faster adoption partly to companies fearing the risk of standing still, and expects AI to enable thousands of winners rather than concentrate the economy in a few firms.
