Los Angeles-based MoGreet, a stealth company in the area of mobile video messaging, has quietly raised at least $1.2M in venture capital from DFJ Frontier. DFJ Frontier, which is an affiliate of Draper Fisher Jurvetson, added MoGreet to its portfolio sometime in August; the recent PwC/NVCA MoneyTree Report pegged the investment at $1.2M. The firm is still in stealth mode.
