At Facebook, Cohler helped drive the company’s strategy, organizational growth and product direction. Previously he was vice president and general manager at the business social networking site LinkedIN, which he helped to found.

"It is difficult to leave my full-time role at Facebook, but Benchmark provides an extraordinary opportunity to build on my experience helping great entrepreneurs and to work side-by-side with some of the best investors, technologists and strategists I have ever known," said Cohler. "The values, investment philosophy and unique team structure at Benchmark are an ideal fit for me.
