John Collison founded the tech company Stripe 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.
