ownCloud
“We have a completely open development process – which means we develop the software together with our community. This means that things like feature requests, roadmap planning, translation work, etc is done in the open with our community. We like to think of this as “Open Innovation”: 1) our community is really committed to ownCloud as they are deeply involved; 2) they help us with development, provide feedback, discuss feature requests, and QA; and 3) together with our community we come up with the software that at the end of the day is stronger than if we developed it ourselves.” – Frank Karlitschek, Cofounder and CTO
