In its series D round, Thinking Phones (formerly Thinking Phone Networks) raised a whopping $56.7 million in venture money to bring the total to $89 Million. (I think that is a record for VoIP, not counting IPO.)
I tried to find revenue numbers but they were not available.
TP bought Whaleback in August. They also have a partnership with Sprint. But I think you trace all the publicity to their being on the Gartner Magic Quadrant so early. And yet they were left off the other UCaaS list I wrote about.
They have plans to double in size and go global, so good luck with that. It's funny to me how all these VoIP players want to go global when they haven't scratched the surface of the US market yet.
