David Sacks leaves Yammer as part of Microsoft reorganization

Satya Nadella’s massive reorganization is more expansive than just cutting former Nokia employees. Yesterday, David Sacks, the founder and former CEO of Yammer, tweeted that he was leaving Microsoft. David was formerly the COO of Paypal.

Mary Jo Foley, the consummate Microsoft watcher, has determined that Yammer is being integrated more closely into the Office 365/Outlook organization, headed by Rajesh Jha. Kristian Andaker has been tapped to run the engineering organization there. Presumably, the non-engineering functions are being consolidated as well.

Prior to this reorganization, Adam Pisoni, the co-founder of Yammer, was CTO at Yammer, and Kris Gale was VP of engineering. I interviewed him a few months ago (see The New Visionaries: Kris Gale), and he suggested at that time that Yammer was having an impact on Microsoft’s engineering approach, an idea that was echoed by Mary Jo Foley:

Microsoft has been integrating Yammer’s enterprise social capabilties with a number of its own products, including Office 365 and SharePoint, since it bought the company. Microsoft has taken a few pages out of Yammer’s playbook, in terms of how to more rapidly update and iterate on its technologies.

We’ll have to see how that works out, and whether other senior folks at Yammer are headed for greener pastures. I have requests for information sent to Gale and Pisoni, and will update if and when I get more deets.
