MailFrontier named to AlwaysOn™ List of Top 100 Private Companies
Company Recognized for Visionary Role in War Against Spam


Palo Alto, CA.– June 23, 2003 – MailFrontier Inc., a next-generation messaging company protecting corporate and individual users from spam, today announced its inclusion on the first-annual AlwaysOn (AO) Top 100 Private Companies list. AlwaysOn, the media company that covers innovation in technology and business, compiled the list with assistance from KPMG’s emerging business practice, KPMG 1Start. The two groups surveyed more than 1,000 venture investors, investment bankers, top entrepreneurs and executives, who nominated more than 700 companies for the competition. The full list can be found at www.alwayson-network.com.

Tony Perkins, AlwaysOn editor, and KPMG 1Start, identified the AO100 companies based on their innovation and demonstrated leadership among their peers in at least two areas: market traction measured by revenue or customer growth and game-changing approaches and technologies that are likely to disrupt existing markets and entrenched players.

In explaining the selection process, Mr. Perkins notes: “Our survey proves that private company innovation is alive and thriving. We believe that many of the companies funded in the last 12 months will end up being some of the biggest names associated with the Internet. To raise money and win customers in this market, private companies must show that their products and services are an order of magnitude above what currently exists in the marketplace.”

“Spam is threatening the viability of email as a communication tool, and we are honored that AlwaysOn recognizes what we are doing to reverse that,” said Pavni Diwanji, CEO and co-founder of MailFrontier.

A reception will be held honoring the winners on July 15, 2003 at AO2003: The Innovation Summit, taking place July 15-17 at Stanford Law School on the Stanford University Campus. The event will feature over 60 keynote-level speakers, 15 sessions, and 2 days of conversation about what's driving the next wave of innovation.
