Twitter’s Demoted Former Consumer Product Chief Exits Company

Twitter Inc.’s former head of consumer product, Daniel Graf, is leaving the microblogging service after he was demoted.

Graf, who was hired from Google Inc. and had been at Twitter since April, was moved into a special projects job in October. He was replaced by Kevin Weil, who was appointed head of product and is the fifth product head at Twitter in as many years.

“Danke team, danke @Twitter! May you succeed in your mission, society needs you!” Graf tweeted today.

The executive shuffle was part of Chief Executive Officer Dick Costolo efforts to release new features more quickly, with Twitter trying to build up its user base and expand its tools for advertisers. The San Francisco-based company has struggled to increase membership fast enough to satisfy investors, even as revenue has risen. Twitter has also cycled through several top executives this year, replacing its chief financial officer and ousting its chief operating officer.

Jim Prosser, a spokesman for Twitter, confirmed Graf’s departure and declined to comment.
