RingCentral Rings Up $12 Million

[qi:086] RingCentral, a Redwood City, Calif.-based VoIP company, has raised $12 million in Series B funding, doubling the amount it raised in its Series A round. New investor DAG Ventures led the latest funding, with existing investors Sequoia Capital and Khosla Ventures participating as well. The company claims some 50,000 customers, making it one of the more successful players in the hosted VoIP sector. I was highly skeptical of RingCentral when it launched, but I guess there are 50,000 reasons why I was wrong. (I am going to post a long overdue review of RingCentral’s service later this month. )
