Steven Sinofsky, the former Microsoft Corp. executive who was pushed out in November, said on his blog that he’s joined venture-firm Andreessen Horowitz as a board partner.
“In this position I will represent the firm on the boards of portfolio companies when the opportunities present themselves, but will not be a full-time member of the firm,” Sinofsky wrote. Sinofsky added that he will keep his current position as executive in residence at Harvard Business School.
Andreessen Horowitz has been staffing up with experienced technology executives since opening in 2009. In addition to founders Marc Andreessen and Ben Horowitz, who have worked together since the 1990s, the firm’s partners also include former OpenTable Inc. Chief Executive Officer Jeff Jordan, IronPort Systems Inc. co-founder Scott Weiss and SuccessFactors Inc. founder Lars Dalgaard.
Andreessen Horowitz, based in Menlo Park, California, confirmed the hiring of Sinofsky in an e-mail and said he will not be an investing partner.
Sinofsky, a 23-year Microsoft veteran, left the Redmond, Washington-based company last year after clashes with executives, including CEO Steve Ballmer, people with knowledge of the matter said in November. Sinofsky was president of the Windows operating system division.
Bloomberg LP, the parent of Bloomberg News, is an investor in Andreessen Horowitz.
