Stefan Glaenzer, the prominent European VC and former chairman of Last.fm and founder of Ricardo.de, has quit his role as Partner at Passion Capital. He co-founded the London-based early-stage firm seven years ago with partners Eileen Burbidge and Robert Dighero. The decision to resign, which the firm’s staff and Limited Partners were informed of last Thursday, is linked to Glaenzer’s arrest and subsequent conviction in 2012 when he pleaded guilty to sexually assaulting a woman on the London Underground Tube network.
