eZ Publish

eZ has an enterprise open source philosophy of "full freedom of open source with total product responsibility." Bard Farstad of eZ described his company's philosophy in a recent One on one interview:

"The eZ Philosophy [is] based on the core values of openness, sharing and innovation, where open source is like a catalyst. And it is simple; if people openly work together sharing their information and knowledge, great innovations will occur.

You can download the free version and learn to use it on your own, or you can buy eZ Publish Premium, which provides the same software functionality, but with guaranteed maintenance and support. eZ, which became profitable as a company for the first time this year, has experienced triple digit growth in sales of its premium product. eZ has lots of media company customers, but more recently has also been attracting financial service industry customers.

eZ is considered first and foremost a WCM product, but it can handle ECM. In addition to the premium version, eZ also offers consulting, training and certification programs as additional revenue-generating service offerings.
