MoveOn is the largest independent, progressive, digitally-connected organizing group in the United States. Launched in 1998, MoveOn pioneered online organizing and advocacy techniques that have become standard in politics, nonprofits, and industry in the U.S. and worldwide. We combine rapid-response political campaigning with deep strategic analysis, rigorous data science and testing, and a culture of grassroots member listening and participation that allows us to consistently and quickly identify opportunities for progressive change–and mobilize millions of members to seize them. MoveOn members step up as leaders by using the MoveOn Petitions DIY organizing platform to create their own petitions and campaigns to drive social change.
