Raising money for a cause? Use Fundable

Fundable is a group money raiser that seems to have a very good model down. An organizer sets up a goal and how many people need to contribute how much money by how much time. Then a description is put in and the waiting starts. If the contributions meet the goal before the time expires, then the organizer must provide to the group what is promised. If the time expires before the goal is met, those that have participated would automatically get their funds refunded by Fundable.
