Under Ballmer’s Reign at Microsoft, 41 VC-Backed Company Acquisitions

Much has been written about Steve Ballmer’s decision to step down as Microsoft CEO and what it says about the technology industry’s migration away from a PC-centric world order.

Here is something else: Over his 13-year reign on the throne of the once dominant software king, Ballmer presided over the acquisition of at least 41 venture-backed technology companies, or roughly three a year.

While it seems like a small number, given the modern day habits of such active acquirers as Google, Facebook and Yahoo, it is nonetheless an interesting record.

At the top of the list is the eye-popping $8.5 billion 2011 purchase of Skype. In the absence of a financial analysis of the benefits of this deal, it is hard to believe the value was fully achieved. Skype’s backers include Index Ventures, Bessemer Venture Partners and Draper Fisher Jurvetson, among others.

A deal that is likely looked upon as being a greater success is the $1.2 billion acquisition in 2012 of Yammer, which was eventually integrated into the Office division. Yammer’s backers included DFJ, Charles River Ventures, Emergence Capital Partners and Khosla Ventures.

Not included on the list is aQuantive, the publicly traded ad network it bought in 2007 for more than $6 billion and then largely wrote off. Not included as well is last week’s announced purchase of Nokia’s cell phone unit, which also is a division of a public company.
