Change.org

Change.org is the world's largest online petition platform, letting anyone start a campaign, gather signatures, and pressure decision-makers on social, political, and consumer issues. Founded in 2007 by Ben Rattray, it now reports more than 580 million users worldwide. The platform operates as a public benefit corporation and, since 2021, is wholly owned by the nonprofit Change.org Foundation. Its stated mission is to empower people everywhere to create the change they want to see and to shift the balance of power between individuals and large institutions.
