Schibler also sits on the board, along with CEO Krish Ramakrishnan; Tom Dyal, managing director from Redpoint Ventures; venture capital consultant Carl Everett; Greg Smitherman, partner at Advent International; and Peter Wagner, general partner from Accel.
The funding announcement comes as company executives say that they expect to make announcements soon about new OEM partners.
