Patrick Collison — Irish Teen to Stripe Billionaire

Patrick Collison is the most understated billionaire on this list, having co-founded Stripe from a rural Irish village of 300 people. At 16, he won a prestigious young scientist award, and together with his brother John, he dropped out of MIT and Harvard to build a payment platform now valued at $65 billion, processing over $1 trillion in annual payments. He became Ireland's youngest self-made billionaire at 31, a title that outperforms #10 Ritesh Agarwal's fastest-recorded rise in India, thanks to Stripe's consistent 30% year-over-year revenue growth. Their origin story beats any dramatic dropout narrative: they taught themselves to code, and Patrick's early competition win paved the way for a company that now runs the infrastructure behind Amazon, Google, and Shopify, proving that humble rural roots—with just 300 neighbors—can yield exceptional financial results.
