PowerBase is a hosted platform that lets social justice organizations manage organizing campaigns in the same way organizers do their work, track member involvement and leadership development over time, accept and track online donations, manage phone banks and door knocking, send mass emails to supporters, link contacts with voter files, track event signups and attendance, and integrate registration and signup pages with your organization’s website.
