Stripe

Stripe processes over $1 trillion in total payment volume annually — making it the financial infrastructure for a significant fraction of the global digital economy, powering payments for Amazon, Google, Shopify, Lyft, and 1 million+ businesses worldwide. Founded in 2010 by brothers Patrick and John Collison (ages 35 and 33 in 2026), Stripe has been valued at $65B following its 2024 secondary share transaction and remains one of the most valuable private companies in the world after choosing to stay private longer than peers. Its Atlas program has incorporated 50,000+ startups globally, and Stripe Financial Connections (open banking API) now covers 95% of US bank accounts. The Collison brothers' story is told in the book 'The Founders' by Jimmy Soni.
