Indiegogo

Founded in 2008 by Danae Ringelmann, Slava Rubin, and Eric Schell, Indiegogo was one of the first platforms to offer crowdfunding. The company's mission is to empower people to unite around ideas that matter to them and bring those ideas to life. Indiegogo enables creators to launch campaigns to raise funds for their projects, offering rewards or perks to backers in exchange for their contributions. In addition to traditional reward-based crowdfunding, the platform has also facilitated equity crowdfunding through partnerships. Its "InDemand" service allows entrepreneurs to continue raising funds and building their community even after their initial campaign goal has been met.
