Yammer Bails On Los Angeles, Heading To Silicon Valley

West Hollywood-based Yammer, the corporate microblogging site inspired by Twitter, is moving from the Los Angeles area to Silicon Valley, according to founder David Sacks. According to Sacks, the entire firm--including its engineering team and executive staff--is moving to the Bay Area, to be closer to the startup scene in Silicon Valley. Sacks said that Geni, which spun out Yammer, remains in West Hollywood. Sacks revealed the move at the Twiistup conference Friday, explained the move by saying that "what I miss are all the technology companies are out of there, and I miss tapping the brain trust up there." Yammer provides a Twitter-like corporate microblogging platform, essentially a version of Twitter restricted to specific corporate domains. The firm was spun out in September 2008 from Geni, and is backed by Charles River Ventures and the Founders Fund.
