Facebook CTO Brett Taylor is leaving the company after three years to start his own company. Taylor’s departure, first reported in AllThingsD, comes barely a month after the social networking giant went public and amid continuing investor concern about the company’s future revenue growth.

Taylor’s oversight of two key areas at Facebook—its developer platform and mobile—will be assumed by two other Facebook executives--Mike Vernal and Cory Ondreijka—according to the report. Vernal joined the company from Facebook in 2008, while Ondreijka came through the 2010 acquisition of startup Walletin.

Taylor, who founded FriendFeed, acquired by Facebook in 2009, didn’t disclose what his next venture will be. But he said he would be starting a new project with another former Google alumnus, Kevin Gibbs. In a statement, Facebook CEO Mark Zuckerberg said he was "proud that we have a culture where great entrepreneurs like Bret join us and have such a big impact."
