On Monday, Yammer, the enterprise-collaboration startup Microsoft bought for $1.2 billion last year, moved from its longtime home in San Francisco's SoMa district to a new headquarters in 1355 Market, the building that's also home to Twitter and One Kings Lane.
Business Insider was on hand for the ribbon-cutting. We spoke to Yammer CEO David Sacks, CTO Adam Pisoni, and a host of employees about the move.
Microsoft's Dan'l Lewin, its top executive in Silicon Valley, was also on hand—the only sign of a very low-key presence for Yammer's new owners.
Lewin told us that the hands-off approach was very intentional, the result of a lot of learning on Microsoft's part on how to integrate startups. He called Yammer a "golden egg" that Microsoft wanted to handle carefully.
It's incubating in a beautiful new nest.
The San Francisco Furniture Mart, as 1355 Market was previously known, was built in 1937—the same year as the Golden Gate Bridge.
Twitter and One Kings Lane are also in the building. A local stationery firm, Patrick & Co., added Yammer to the list of new customers it hoped to accommodate.
Yammer's old office was convenient for South Bay employees, who could walk a block from the Caltrain station. Yammer doesn't offer private shuttles, but there is an express shuttle bus, the 83X, which takes them to Yammer's new Mid-Market location.
