The New Open Source CRM: Gamified, Mobile, Social.

Zurmo is an Open Source Customer Relationship Management (CRM) application that is mobile, social, and gamified. We use a test-driven methodology for building every part of the application. This means you can create and maintain a custom-built CRM system or platform with the assurance that future updates are not going to break your installation. Head over to the forums to learn more.
