"1. Paid Users: Open-Xchange quadrupled the number of
paid users to 8.4 million in 2008, suggesting the company is
rapidly approaching 10 million paid users
"2. Software as a Service: More and more of the deployments
involve solutions providers hosting Open-Xchange for their
customers. In other words, VARs are becoming SaaS centers. And CEO
Laguna de la Vera says Open-Xchange has no plans to host
applications for customers. Translation: The Open-Xchange SaaS
market is designed purely for channel partners.
"Plenty of open source companies are making similar moves.
Earlier this week, The VAR Guy described how OpenBI -- an IT
consulting firm -- built a business intelligence system in
Amazon.com's Elastic Compute Cloud. The system is based on
Pentaho’s open source software."
