Public policy work can be challenging. We build software that makes it easier. Muster is grassroots advocacy software for nonprofits, associations, chambers of commerce, and corporations. We help organizations turn supporters into advocates and get their voices in front of the lawmakers who make decisions about the issues they care about. With Muster, you can launch an action alert in minutes, connect advocates with their elected officials at every level of government, and see exactly who's engaging and where. Every email sent, call made, and meeting held is tracked in one place, so you can show your board, members, and stakeholders the real impact of your advocacy program. Most of the people we work with aren't full-time lobbyists. They're comms managers who inherited the advocacy program, or association directors doing this alongside ten other jobs. We built Muster for them, and our customers have noticed: G2 users have named Muster the easiest to use and the best support in Public Affairs & Advocacy software. We also believe local advocacy matters just as much as Capitol Hill. Some of the biggest wins happen in statehouses, county boards, and city councils, and our tools are built to help you show up there too. Whether you're running your first campaign or your hundredth, we're here to help you make it count. Request a demo at muster.com.
