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. They 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.
