In May of this year 2950 Pacific landed on the market asking $16.5M. It sold quickly, and by July it was confirmed that Zynga founder Mark Pincus and his One Kings Lane founder wife Ali Pincus had bought the abode for $16M. The 7-bed, 6-bath, 11,500-square-foot home is perched atop famed Billionaire's Row, where tech titans seem to be buying up plenty of available real estate.

Property highlights include straight-on views of the Golden Gate Bridge and stairs directly to Baker Beach from the backyard.
