CiviCRM is web-based, open source, Constituent Relationship Management (CRM) software geared toward meeting the needs of non-profit and other civic-sector organizations.

Forging and growing strong relationships with constituents is about more than collecting and tracking constituent data - it is about sustaining relationships with supporters over time. To this end, CiviCRM has created a robust web-based, open source, highly customizable, CRM to meet organizations’ highest expectations right out-of-the box. Each new release of this open source software reflects the very real needs of its users as enhancements are continually given back to the community.

With CiviCRM's robust feature set, organizations can further their mission through contact management, fundraising, event management, member management, mass e-mail marketing, peer-to-peer campaigns, case management, and much more.

CiviCRM is localized in over 20 languages including: Chinese (Taiwan, China), Dutch, English (Australia, Canada, U.S., UK), French (France, Canada), German, Italian, Japanese, Russian, and Swedish.
