CiviCRM is an open source CRM built by a community of contributors and supporters, and coordinated by the Core Team. CiviCRM is web-based software used by a diverse range of organisations, particularly not-for-profit organizations (nonprofits and civic sector organizations). CiviCRM offers a complete feature set out of the box and can integrate with your website. CiviCRM is created and used by a global community of tens of thousands of individuals and organisations. Our vision is that 'all organisations – regardless of their size, budget, or focus – have access to an amazing CRM to engage their contacts and achieve their missions'.
Mobilize is a volunteer management platform and network that enables activists, progressive organizations and Democratic campaigns to connect and win.
