eXo began as an open source project in 2002, as the industry's first Java portlet container. The eXo Project catalyzed a portal market dominated by a handful of very large vendors selling six-figure software and lock in. It opened the floodgates to choice in this market, and customers came. The eXo Project grew into a company in 2003, as a response to customer demand. Today, eXo is a rapidly growing global company, with U. S. headquarters in San Francisco, California, global headquarters in France, and offices in Tunisia, Ukraine, and Vietnam. The company has established technology leadership and proven value by their large European installed base and strategic partnership with Red Hat.
