Kickstarter
From the Kickstarter website:
"Kickstarter is a funding platform for creative projects — everything from films, games, and music to art, design, and technology. Our mission is to help bring creative projects to life. We are a Public Benefit Corporation based in Brooklyn, New York.
(..)
Everything on Kickstarter must be a project. A project has a clear goal, like making an album, a book, or a work of art. A project will eventually be completed, and something will be produced by it.
We allow creative projects in the worlds of Art, Comics, Crafts, Dance, Design, Fashion, Film & Video, Food, Games, Journalism, Music, Photography, Publishing, Technology, and Theater.
Every project creator sets their project's funding goal and deadline. If people like the project, they can pledge money to make it happen. If the project succeeds in reaching its funding goal, all backers' credit cards are charged when time expires.
If the project falls short, no one is charged. Funding on Kickstarter is all-or-nothing.
How does Kickstarter make money?
If a project is successfully funded, Kickstarter applies a 5% fee to the funds collected. All pledges are processed securely by our third-party payments partner, Stripe. These payment processing fees work out to roughly 3-5%. View the fee breakdowns. If the project does not reach its funding goal, there are no fees.
What do backers get in return?
Backers that support a project on Kickstarter get an inside look at the creative process, and help that project come to life. They also get to choose from a variety of unique rewards offered by the project creator.
Rewards vary from project to project, but often include a copy of what is being produced (CD, DVD, book, etc.) or an experience unique to the project. Backers can also opt to pledge for a project without selecting a reward.
Project creators keep 100% ownership of their work, and Kickstarter cannot be used to offer equity, financial returns, or to solicit loans."
