Ad tech company Turn has tapped Bruce Falck to be its new CEO. Falck was formerly COO at Brightroll, where he served for fewer than six months before Yahoo acquired the company. Prior to joining Brightroll, he spent eight years at Google, where he helped build its digital ad tech businesses. “Fundamentally it came down to the fact that he built multiple highly successful multi-billion dollar advertising technology businesses,” said Turn Chairman Jim Barnett.
