Facebook's chief technology officer, Bret Taylor, is leaving the Menlo Park, Calif., company, the first major defection since its disappointing debut on the public markets last month.
Rumblings that Taylor would leave Facebook began circulating in Silicon Valley last month around the time of the initial public stock offering.
"I've really enjoyed working with Bret and getting to know him as a friend and teammate," Facebook founder and Chief Executive officer Mark Zuckerberg said in an emailed statement. "I'm grateful for all he has done for Facebook and I'm proud of what he and his teams have built."
Taylor, a former Google employee who has been Facebook's chief technology officer for two years, said he was leaving Facebook to work on a new start-up with Kevin Gibbs, a Google engineer.
