The youngest self-made billionaire in the world has been confirmed to be John Collison. He is the co-founder and President of Stripe.
He founded the tech company along with his older brother Patrick Collison, Stripe's CEO, in 2010, when he was only 19.
Now Collison, 27, can call himself the youngest self-made billionaire in the world, with a net worth totaling $1.1 billion after Stripe's $9 billion valuation in 2016.
The company was designed to transform the way websites accept online payments, and it's a favorite of huge companies like Lyft and Facebook.
Though the siblings have struck Silicon Valley gold, they haven't forgotten their humble roots in small-town Ireland.
John Collison who is originally from Ireland went to the US to attend Harvard - until he dropped out to focus on Stripe in Silicon Valley.
Today, Collison enjoys flying planes, running, and hiking with members of the Stripe team.
