Former Microsoft exec Steven Sinofsky joins Andreessen Horowitz as board member

Back in November, former Windows head Steven Sinofsky abruptly left Microsoft, leaving many to wonder where the tech exec would land next. Now, we know: first reported by the tech blog AllThingsD, the 20-year-plus Microsoft veteran has joined Andreessen Horowitz as a board member.
Sinofsky shared the news on his personal blog, explaining that board partners at the top-tier Silicon Valley venture capital firm have a “unique” role.

“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,” he wrote.

According to AllThingsD, Sinofsky had been advising Andreessen Horowitz since the beginning of the year. But, in this official position, he said that while venture capital is relatively new to him, he’s looking forward to sharing his background in product development and scaling teams to new companies.
As my colleague Barb Darrow wrote earlier this summer, Sinofsky’s options were somewhat limited as his retirement agreement precluded him from accepting direct or indirect employment from Microsoft rivals Amazon (s AMZN), Apple (s AAPL), EMC (s EMC), Google (s GOOG), Facebook (s FB), Oracle (s ORCL) or VMware (s VMW).
In addition to working at Andreessen Horowitz, Sinofsky said he plans to maintain his entrepreneur-in-residence position with Harvard Business School and keep himself busy with other business and product development projects.
