Raising money through crowd sourcing is really taking off. The latest entry is phundraiser.com. Here's what they do - straight from their website.
Phundraiser is an innovative way to fund endeavors that require money. Through crowdfunding, or getting a large number of interested individuals to each pledge a small amount of money for a common goal, Phundraiser allows Promoters to raise the money they need to make their ideas actually happen. Using Phundraiser’s all-or-nothing functionality, Pledgers can rest comfortably because their pledge is truly a pledge that is contingent upon the Promoter raising enough funds to make their ideas a success.
So if you've got a project to fund, Phundraise it!
