Richest billionaires under 40
Facebook has created more billionaires under 40 than any other company, according to a new ranking.
In the Wealth-X list of 10 richest billionaires under 40, four made most or all of their fortune from Facebook.
Mark Zuckerberg tops the list with estimated wealth of $35.1 billion. His fellow Facebook co-founder and fellow 30-year-old, Dustin Moskovitz, ranked second, with $7.7 billion. And Sean Parker, the Web bad boy who has founded several companies but made his biggest coin from Facebook, comes in at number five with $5.2 billion.
If you add in Eduardo Saverin, another co-founder, the fresh-faced Facebookers have a combined $52 billion.
You could even argue that Jan Koum, the third-ranked under-40 rich guy, made his fortune in large part from Facebook, since he sold his mobile messaging platform, WhatsApp, to the social media site.
