Matt Graves, formerly head of marketing communications at social music service imeem, has joined Twitter’s growing PR department. imeem was acquired by MySpace in November 2009 and subsequently shut down.
Before imeem, Graves was director of public relations at RealNetworks.
463 Communications Partner Sean Garrett joined Twitter as the company’s first internal PR executive — with the title vp of communications — this past February. His first hire was Carolyn Penner from Google in April.
“I’m looking to hire two relatively senior people and one junior person. I am not looking to hire an agency anytime soon,” Garrett told PRNewser in March.
