CEO David Sacks: ‘Yammer Will Remain Under My Direction’

Yesterday it was made official that Microsoft was acquiring Yammer for $1.2 billion in cash.

“The acquisition of Yammer underscores our commitment to deliver technology that businesses need and people love,” said Steve Ballmer, CEO, Microsoft. “Yammer adds a best-in-class enterprise social networking service to Microsoft’s growing portfolio of complementary cloud services.”

“When we started Yammer four years ago, we set out to do something big,” Yammer CEO David Sacks said. “We had a vision for how social networking could change the way we work. Joining Microsoft will accelerate that vision and give us access to the technologies, expertise and resources we’ll need to scale and innovate.”

This morning David emailed all Yammer customers to let them know what’s going on. In the memo, David confirmed that “the team will remain under my direction,” albeit within the Microsoft Office Division. And while Yammer will be deeply integrated with various Microsoft products, such as SharePoint, Office365, and most notably Skype, the core Yammer produce will remain: “as a Yammer customer, you will continue to get a secure, private social network—delivered with the same focus on simplicity, innovation, and cross-platform experiences,” David affirmed.

Launched in 2008, Yammer now has more than five million corporate users, including employees at 85% of the Fortune 500.
