John Collison Bio
John Collison (born 6 August 1990) is an Irish entrepreneur best known as the co-founder and president of Stripe, the global payments company he launched with his brother Patrick in 2010. Born in Dromineer, County Tipperary, he began building technology companies as a teenager in Limerick before moving to the United States to study and work in Silicon Valley. In 2016, he and his brother became the world’s youngest self-made billionaires after a major investment valued Stripe at roughly $9.2 billion, and as of 2025 Bloomberg estimated his personal net worth at about US$9.3 billion.
Beyond Stripe, Collison is a licensed pilot and an accomplished pianist, and he has invested in property in Ireland, including historic estates in County Laois. He is widely regarded as one of the most influential figures in modern financial technology.
Early Life and Background
John Collison was born on 6 August 1990 in Dromineer, a small village in County Tipperary, Ireland. He grew up in Limerick, where he and his older brother Patrick developed an early interest in computers and entrepreneurship. The brothers were introduced to programming at a young age, and their parents encouraged curiosity in science, technology, and business.
Collison attended Castletroy College in Limerick for his secondary education. After leaving for the United States, he returned to complete the Irish Leaving Certificate examination in 2009, where he earned eight A1 grades and two A2 grades, one of the strongest results in the country that year. His strong academic record reflected the same discipline that would later shape his professional career.
Path to Co-founder and President of Stripe
John Collison’s path to leading Stripe began in 2007, when he and Patrick founded Shuppa, an early software venture based in Limerick. The company soon merged with Auctomatic, a software firm that built tools for eBay sellers. Auctomatic received backing from Y Combinator and investor Chris Sacca, and the experience exposed the young Collison to the culture of Silicon Valley.
In March 2008, Auctomatic was acquired for $5 million, a notable outcome for a company co-founded by a 17-year-old. After the sale, Collison returned to Ireland to finish school, then matriculated at Harvard University in September 2009. He left Harvard shortly afterward to build Stripe, a developer-friendly payments platform, together with Patrick in 2010. The new company attracted early backing from Elon Musk, Peter Thiel, Max Levchin, and Sequoia Capital, giving Collison a clear path into his current role as president of Stripe.
