Russian Billionaire Yuri Milner Breaks Record with $100M Manse

Yuri Milner, the venture capitalist who helped put Facebook on the map, has invested $100 million in his own start-up of sorts – a 25,500 square-foot mansion in Los Altos, Calif. The purchase marks the highest known price paid for a single-family home in the U.S., according to the Wall Street Journal.

You may have heard of the Russian billionaire in the context of tech powerhouses Facebook, Zynga and Groupon – all of which he has invested significant capital in. Milner's first and most notorious investment through his Moscow-based Digital Sky Technologies (DST) was a $200 million check to Facebook in 2009. Today, that investment is valued at $10 billion, according to the Wall Street Journal's Venture Capital Dispatch.

The French chateau-style estate includes five bedrooms, nine bathrooms, a home theater, wine cellar, spa and gym, tennis court, car wash, swimming pool and formal gardens. (See photos below.)
