What is Open Atrium?
Open Atrium is open source collaboration software that enables organizations to securely connect their teams, projects, and knowledge. A powerful solution, Open Atrium’s framework allows your organization to easily integrate your existing software, while remaining flexible enough to change as your organization grows. With Open Atrium, you can better communicate, educate, and inform your organization by creating solutions such as an intranet, social collaboration platform, web portal, or learning management system.
Open Atrium is an intranet in a box that has group spaces to allow different teams to have their own conversations and collaboration.
