Vivox, boston-area leading provider of integrated voice services for online games and virtual worlds has announced that it has secured $7.8 million in a second round of equity financing led by Benchmark Capital. Proceeds from the round will fund product development, sales support and marketing. You may have seen the Vivox phones around SecondLife or used their voice technology in an online game. I blogged my meeting with Vivox CEO Rob Seaver back in December of 2005.
