The founder of Toronto mobile content producer and distributor SilverBirch Inc. announced he has stepped down as CEO to make room for the founder of another mobile content firm. Kevin Birch will relinquish the top job at SilverBirch and move into the role of chief technology officer (CTO) and president of the company’s product development division. The roots of SilverBirch go back to 2002, when Birch and three partners organized the reverse-takeover of IVP Technology Corp. with Birch installed as VP and CTO. He then created SilverBirch as a spinoff of the firm’s healthcare technology consulting practice. Finally, SilverBirch and IVP parted company in 2004 with a management buyout engineered by Birch.
