Co-founder
John Collison is President at Stripe, the payments technology company he co-founded in 2010 with his brother Patrick Collison. As president, Collison oversees operations, strategy, and business development, working alongside Patrick, who serves as chief executive officer. Stripe provides financial infrastructure and payments technology, and as of February 2026 carried a valuation of $159 billion.
Collison was born in August 1990 in Dromineer, County Tipperary, Ireland. Before Stripe, he co-founded Auctomatic with his brother Patrick — a software company building tools for high-volume sellers on platforms such as eBay, which was acquired in March 2008 for approximately $5 million when Collison was seventeen. The brothers had participated in Y Combinator through their work on Auctomatic. In November 2016, following a funding round that valued Stripe at $9.2 billion, Collison became the youngest self-made billionaire in the world, with a net worth estimated at $9.3 billion as of 2026 according to the Bloomberg Billionaires Index. Stripe received early backing from Elon Musk, Peter Thiel, Max Levchin, and Sequoia Capital. Collison enrolled at Harvard University in September 2009 and dropped out the following year to build Stripe. He holds a Federal Aviation Administration Aircraft Flight Instructor certification and is also a pianist.
