Change.org is a social network for social activism, incorporating nonprofits, politicians, and people across the globe.

One of the first to respond, one of the last to leave. For more than 70 years, the International Rescue Committee has been a leader in humanitarian relief. They mobilize quickly, bringing sustained support to regions torn apart by violence and deprivation. They provide a fresh start in the U.S. for refugees. And we advocate tirelessly on behalf of the displaced, addressing the root causes of violence and standing up for the world’s most vulnerable populations.

Fundable.org lets groups of people pool funds to make purchases or raise money. Similar to online auctions, Fundable’s pages, called “group actions,” are created by people who use this site. Each group action has a description of how much money needs to be collected and what it will do. Once enough pledges (not payments) have been collected, Fundable turns them into real payments and sends the total to the group action’s organizer.

ChipIn’s mission is to make it easy to collect money. They enable users to organize group payments and fundraisers (”ChipIns”) in a quick, easy, and secure way. They also make it simple for organizers to publicize their ChipIns, by providing powerful fundraising widgets that can be embedded in social media.
