37-year-old WhatsApp co-founder Jan Koum was born in the Ukraine. He arrived in the U.S. when he 16-years-old and his family struggled. They lived on food stamps, venture capitalist Jim Goetz revealed in a blog post.
In fact, Koum's family picked up their food stamps only a couple of blocks away from WhatsApp's offices in Mountain View, Calif., reports Wired's David Rowan.
Flash forward to today, when Facebook announced it was buying WhatsApp for a stunning $19 billion in cash and stock. Even if the deal falls through, axed by regulators, Facebook has agreed to pay WhatsApp $2 billion in cash and stocks.
Forbes estimates that Koum holds about a 45% stake in the company, while his co-founder Brian Acton's stake is estimated at over 20%.
That would make Koum worth $6.8 billion and Acton worth a at least $3 billion as of Facebook's closing share price on Wednesday.
From food stamps to billionaire, that's an incredible journey.
