MX Logic Raises $11 Million in New Equity Financing

Denver, CO – MX Logic, Inc., a leading provider of innovative email defense solutions that ensure email protection and security for businesses, service providers, government organizations, resellers and their customers, today announced it has received $11 million in new funding.

The round was led by UV Partners with participation from River Cities Capital Funds as well as follow-on participation from existing investors Adams Street Partners, Grayhawk Venture Partners and Vista Ventures. This funding of MX Logic brings total financing to $18.5 million. MX Logic will use the capital to continue to enhance its solution suite, build out its channel partner program, fund global expansion and pursue strategic partnerships.

“We invest in companies which provide solutions that meet a demonstrated market need and have a track record of executing successfully on their vision,” said Carl Ledbetter, a partner at UV Partners. “MX Logic’s customer base and revenue has grown more than 900 percent over the last twelve months. The MX Logic leadership team has shown it can deliver innovative product offerings that relieve customers of the pain and costs associated with handling spam, viruses, worms and other email threats.”

Email security is a growing market, one that according to analysts will reach between $4 billion to $5 billion. Robust spam, virus and worm detection has become critical as the volume and costs associated with email threats continue to rise. Ferris Research estimates that in 2003, the total cost of spam to U.S. businesses in lost productivity was $10 billion. During the month of August, 92 percent of the email MX Logic filtered on behalf its over 2,800 customers was spam. Viruses and worm threats are also associated with devastating costs. SoBig.F damage estimates range from $500 million to more than $1 billion in lost productivity, hours wasted and lost sales.

“MX Logic is committed to delivering the most accurate, reliable and cost-effective email defense solutions available,” said John Street, CEO, MX Logic. “Our most recent round of funding will help us continue to deliver cutting-edge solutions, support our expanding customer base and continue to anticipate and exceed our customers’ needs.”

During 2004, MX Logic has achieved several industry milestones, including:
