FORT MYERS, Fla.--July 11, 2006--CallMiner, a leading developer of enterprise-class speech analytics software, today announced that it has received an additional investment of $10 million. The investment was made by a combination of Sigma Partners, Inflexion Partners and Intersouth Partners. Sigma Partners, which led the Series B round, is a new investor in CallMiner and will add Robert Davoli, Sigma's managing partner, to CallMiner's Board of Directors. Both Inflexion and Intersouth previously participated in CallMiner's initial $2.8 million Series A Financing in 2004 and elected to re-invest additional capital into CallMiner as part of this Series B round.

CallMiner intends to use proceeds from this financing toward the development of new sales channels, the expansion of existing sales channels, aggressive marketing, and toward the creation and deployment of improvements to the company's innovative core technologies.

Founded in 2002, CallMiner provides speech analytics software, enabling enterprise customers to uncover actionable business intelligence from call center recordings. Millions of hours of customer calls are recorded daily, with only a fraction of those calls mined to gain insight into customer and agent interactions. CallMiner's proprietary software provides detailed analysis of agent/customer interactions, allowing enterprise users to listen to what their customers want and to improve agent performance and business efficiencies.

In addition, CallMiner's new patent-pending Virtual Server Room (VSR) technology enables organizations to implement enterprise-level applications in an extremely cost-effective basis by utilizing existing but otherwise unused computing resources. VSR works hand-in-hand with CallMiner's core speech analytics applications, but can also be independently licensed and deployed to power other, unrelated enterprise-level software applications.

"This new round of capital comes at a key time for CallMiner," said Jeff Gallino, CEO of CallMiner. "At a time when companies are universally looking to maximize every piece of prospective business intelligence at their disposal, CallMiner is able to provide cost-effective tools that unlock critical customer-centric information that would otherwise have remained buried in thousands upon thousands of hours of recorded calls. CallMiner's cutting-edge technology is fully operational and proven; our customer base is increasing, and our market is growing exponentially. With the additional investment, we now have the liquidity necessary to significantly expand our sales and marketing efforts to maintain our market leading position. Moreover, we are also pleased to be adding Sigma Partners to our Board to assist with both our strategic and tactical planning."

"We're excited to pursue this opportunity with CallMiner," said Robert Davoli, managing director of Sigma Partners. "CallMiner has several of the elements that we view as essential to success: great technology, a sales-oriented focus, and a fantastic market opportunity. In addition, with a strong board and management team, we believe that CallMiner will be able to effectively execute their business plan, maintain their leading market stance, and position CallMiner to become a key player in the overall market for business intelligence."
