1. Drew Houston

We get started with a name you probably have never heard of unless you’re into the ever-growing and always lucrative, tech world. You may well, however, have heard of Dropbox a platform that Houston created.

At still only 34 years of age, and with an estimated fortune of $3.4 billion, it is unlikely that Mr Houston will live out his days in San Francisco as a single for much longer. Who’d have thought that a simple file sharing idea could make one person so rich?
