Topping the list are partners Paul Sciarra and Ben Silbermann. The duo launched Pinterest in March 2010. Less than two years later, the site has an astounding 1.1 million users, giving it the third largest user base behind Facebook and Twitter. Coming in second place is Instagram creator Kevin Systrom. It's hard to believe Instagram has only been around since October 2010. It already boasts a whopping 100 million users and has given Systrom financial freedom.
Rounding out the top five are Twitter's own Jack Dorsey, Turntable.fm mastermind Billy Chasen and RockMelt's Eric Vishria.
