Software: Matrix Invests $13.8 million in Digium

Matrix Partners dialed in a $13.8-million stake in Digium, putting in line a veteran open-source backer for the startup.

Venture capital firm Matrix was involved with the blockbuster open-source deal for Jboss, which was scooped up by Red Hat.

Digium is an open-source developer of phone systems software, with a product called Asterisk. The open-source company plans to use the funding to offer more services for businesses. Meanwhile, Digium said that it’s been profitable since 2002.

Mark Spencer, president of Digium and creator of Asterisk, said it’s not entirely about the money, that connecting with the right VC to develop the company was important.

“We wanted to find some sort of partner that would help us grow, expand into newer areas and refine our model to take advantage of what we have developed in Asterisk,” Mr. Spencer said.
