Kickstarter, crowdfunding for people who make stuff.
Kickstarter lets creative people -- journalists, artists, musicians, game developers, entrepreneurs, bloggers -- raise money for their projects by connecting directly with their fans, who receive exclusive access and rewards in exchange for their patronage. Set a fundraising goal, deadline, and a set of rewards for backers. If the goal's reached by the deadline, then everyone's charged and backers get their goodies. If not, nobody's charged. Make stuff, without the upfront risk!
I advised this startup and sit on the board, and am very proud of the work the team's done. I'd love to know what you guys think.
Note: Anyone can sign up and back projects, but creating your own project is currently invite-only and restricted to the United States. Let me know if you want an invite!
