Greg Martin, the partner heading up Redpoint Ventures' Los Angeles office, has reportedly left the firm, according to a report from the Private Equity Insider. Martin is no longer listed on Redpoint's web site, was not listed in its latest fundraising documents, and declined to comment on the story. Martin had actually disappeared from Redpoint's site in February, when Redpoint announced it had closed its $400M, Redpoint IV early stage venture capital firm. Martin had led Redpoint's investment in Networks in Motion, TelASIC Communications, WebVisible, SOA Software, and a number of other local firms.
