Change.org

Change.org is the world's largest petition platform, used by more than 580 million people across 196 countries to start campaigns, mobilize supporters, and pressure government and corporate decision makers. About 2,000 new petitions launch and 500,000 signatures are collected daily, and journalists routinely source stories from the platform. It operates as a Public Benefit Corporation wholly owned by the nonprofit Change.org Foundation, sustained by user memberships and contributions rather than ads. For a PM, this is a mission-driven civic-tech environment running a massive consumer marketplace of campaigns at global scale.
