About Tendenci CMS

Tendenci is a content management system (CMS) specifically designed for nonprofit and community organizations with the features associations require including online donation management, membership management, event registrations, and communications tools for movement building built into the Core of the software.

Tendenci empowers association managers with the online tools they need to communicate, manage and conduct transactions with their Community of donors, supporters, volunteers, and members. Tendenci is fun to use and simplifies the process to deploy and set-up a complex website in one highly-customizable software package.

The name 'Tendenci' was originally created by Randy Sarinas. The original logo, branding, and colors were designed by Aaron Long.
