CrowdFunder: The Power of the Crowd in the Community
CrowdFunder is a great new site that helps individuals raising money within their communities by uniting people with common interests. The concept is pretty self-explanatory and follows the power of the crowdsourcing model: a little money x a lot of people = the power of crowdfunding. Essentially it works the same way as charity sponsorship sites like Just Giving, with one crucial difference: if the total isn't achieved in the time specified everyone gets their money back.
Rather than being charity-driven the site revolves around community-based projects, aiming to help users raise funds by ‘leveraging your offline and online reputations in the community where you live' and making it easy to collect from a group of your friends for non-charitable donations ie to communally pay for a party / buy a present / sponsor the creation of your entrepreneurial brainwaves.
