The power to scale your advocacy impact

Petition campaigns that drive results

Create petition pages in minutes and watch signatures roll in. Automatically collect supporter information, send confirmation emails, and move petition signers into deeper engagement pathways.

Elected official outreach that applies pressure

Coordinate email and phone campaigns targeting decision-makers. Track which supporters contacted which officials to measure your advocacy reach and demonstrate constituent support.

Event organizing that builds community

Host town halls, training sessions, and rallies that bring supporters together. Manage RSVPs, send reminders, and turn event attendees into ongoing volunteers.

Grassroots fundraising that sustains your work

Build a base of recurring donors with personalized asks based on giving history. Enable peer-to-peer fundraising so advocates can raise money from their own networks.

Built for advocacy at every scale

Issue-based campaigns

Single-issue organizations can laser-focus supporter engagement around specific policy goals and mobilization moments.

Multi-issue advocacy

Organizations working across multiple policy areas can segment supporters by interest and coordinate sophisticated campaigns on different fronts.

Coalition movements

Large networks and coalitions can manage multiple chapters, share resources, and coordinate national campaigns while maintaining local autonomy.
