Communications service provider Voxeo announced that it purchased IMified, a hosted development platform for instant messaging applications, for an undisclosed amount. The deal is part of a broader acquisition startegy for Voxeo, which has already gobbled up two companies this year and has designs on three more. It hopes to provide its customers with more conversational modes of communication over any medium.

Voxeo has remained fairly immune from the downturn, seeing a 105 percent jump in revenue from last year. IMified will add a new dimension to its business, bringing with it a community of 7,500 developers who have created IM applications for notification systems, customer surveys and online bots. Its service will continue uninterrupted.

Based in Orlando, Fla., Voxeo has taken capital from Mayfield Fund and Crosspoint Venture Partners, but has since bought back the shares to make it an entirely management and employee-owned company. Voxeo plans to sell between 5 and 15 percent of its shares to raise $50 million.
