Telecom expense management providers Rivermine and BBR Wireless will merge under the Rivermine name to serve their installed base of 225 companies, according to an announcement Thursday.

Mark Logan will remain as president and CEO of Rivermine while Jim Carroll, president and CEO of BBR Wireless Management, will assume the title and role of executive vice president of global wireless services in the merged company. In another move, Ray Moncrief of the Southern Appalachian Fund will join Rivermine's board of directors. The Southern Appalachian Fund is BBR's lead investor.

Logan described the rationale for carrying out the merger. "The combined company will allow us to satisfy the increased demand for unified wireless and wireline solutions across the globe," he said in a statement. "This merger is a natural progression from our established partnership."

The two firms took an important step towards combining their respective operations earlier this year when they began integrating many of their offerings.

Rivermine noted that the merged company's global channel partners -- including two of the largest IT outsourcing and systems integration firms with offices in more than 170 countries -- will be able to deliver Rivermine's unified solutions to their domestic and international customer bases.
