How does it work?


SupporterBase is designed to empower your volunteer leaders, simplify your distributed organizing processes, safeguard supporter data and protect your reputation.

The SupporterBase suite includes two core components to power your supporter-led campaigns and community groups:

  • Your own SupporterBase Website

    A central NationBuilder website and custom theme where supporters can find nearby action groups, sign up to join, contact local leaders, RSVP to upcoming events or even start the process of creating their own group.
