Concursive

http://www.concursive.com/

Founded in 2000 as Centric CRM, Concursive, like some others in its space, is trying to expand its reach beyond CRM into other business applications. The four major modules in ConcourseSuite are CRM, Web, Content and Team (which deals with collaboration), and they can be deployed individually or as an integrated suite in either Software as a Service (SaaS) or on-premise versions. The Centric product operated under the proprietary Centric Public License, but since the company changed its name in 2007 it's also changed its take on open source licensing and now uses both the older licenses and licenses approved by the Open Source Initiative consortium. The enterprise software is developed with Java/J2EE and Concursive's developer community now numbers more than 15,000 registered members.
