Crowdfunding allows artists, entrepreneurs and startups to raise money for projects or ventures from many individuals online, typically in exchange for rewards or equity. Kickstarter is geared towards creative projects, requiring a funding goal and deadline, while taking 5-9% of funds raised. Indiegogo accepts any projects and lets keep funds raised even if unfunded, but is more cluttered with 10,000 projects. Both sites can help startups generate buzz and proof of concept in addition to raising funds.
