After hearing a segment about Fundable on Marketplace (NPR), I took a look at their offering.
It sounds like a good way to raise Funds for your kids PTA, Library, Museum, Pet Shelter and other local needs.

Musicians or Filmmakers or Entrepreneurs could consider it to get seed money for their new endeavour.
