As a non profit committed to the public good itself, CiviCRM understands that 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. Unlike proprietary software, 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.
Provided a robust feature set, organizations realize their mission via CiviCRM through contact management, fundraising, event management, member management, mass e-mail marketing, peer-to-peer campaigns, case management, and much more.
