Today as citizens of the world, we face a daunting array of social and environmental problems ranging from health care and education to global warming and economic inequality. For each of these issues, whether local or global in scope, there are millions of people who care passionately about working for change but lack the information and opportunities necessary to translate their interest into effective action.

Change.org aims to address this need by serving as the central platform informing and empowering movements for social change around the most important issues of our time.

Change.org is a social entrepreneurship venture based in San Francisco, CA. The company was founded by Ben Rattray in the summer of 2005, and with the support of a friend from Stanford, Mark Dimas, and a founding team of Darren Haas, Rajiv Gupta, and Adam Cheyer, Change.org launched the first version of its site in 2007.
