Israeli Adam Neumann, the co-founder and CEO of WeWork, made it onto Forbes magazine's list of America's Richest Entrepreneurs Under 40. Ranked 16 in the rankings, Neumann's net worth was estimated by the magazine at about $1.5 billion. "Raised on a kibbutz in Israel, the 36-year-old CEO of WeWork Adam Neumann has turned communal work spaces that rent for as low as $45 a month into a $10 billion business," the magazine said. He launched the company five years ago with Miguel McKelvyand and has since raised more than $900 million from investors like Goldman Sachs, JP Morgan Chase, and Benchmark Capital. WeWork has business centers in 12 U.S. cities, London, Amsterdam and Israel. Thirty-four of the top 40 made their money in high-tech, in a list topped by Facebook's Mark Zuckerberg.
