Kickstarter is an American crowdfunding platform founded in 2008 in San Francisco. It allows users to raise money for creative projects or start-up businesses. It charges a 5% fee on successful contributions in addition to credit card processing fees. Fifteen million people visit the site each month. The founders were inspired to create an alternative funding source after having difficulties funding creative projects. Kickstarter allows users to create pages for funding campaigns with perks for different contribution levels and then promote their projects on social media.
