Marc Fleury started the JBoss project in 1999 in order to advance his middleware research interests. JBoss Group, LLC was incorporated in 2001 in Atlanta, Georgia. JBoss became a corporation under the name JBoss, Inc. in 2004. It was a C corporation headquartered in Atlanta, GA which owned the copyright and trademarks associated with JBoss.

In early 2006, Oracle Corporation, a major distributor of database software, had been looking to buy JBoss Inc. for an estimated $400 million. The acquisition would have enabled Oracle to compete with rivals BEA Systems and IBM in the middleware market (Oracle eventually acquired BEA in April 2008). On April 10, 2006, however, Red Hat announced that they were buying JBoss for $420 million. Red Hat and JBoss have since completed the acquisition.
