Mike Cassidy has left his position as CEO of online gaming platform Xfire to join venture capital firm Benchmark Capital.
Cassidy headed up the rapid growth of the Xfire community platform, which has 7 million registered users. Viacom bought Xfire in 2006 for $110 million, placing the firm in its MTV Networks unit.
At Benchmark, Cassidy will act as Entrepreneur in Residence, advising on new business opportunities in the consumer Internet market.
Prior to Xfire, he led two other companies—search engine Direct Hit and computer telephony tools company Stylus Innovation—to acquisitions by larger firms.
Cassidy co-founded Xfire in 2003. “I am a serial entrepreneur and love the challenge of creating something new and different,” he said in a statement.
Former EA Mobile senior VP Mitch Lasky left his company for Benchmark Capital earlier this year.
