If I were a banker, I'd be feeling a little uncomfortable. It seems a new digital disruption is on its way, about to do to banking what iTunes did to music and Amazon did to product sales.
It's called crowdfunding and it has a close cousin called peer-to-peer lending (P2P). Both are alternative ways to get money for your idea or your business from people who pool small amounts of money together. Generally using an online platform, crowdfunding and P2P bring borrowers and lenders together while bypassing the banking middleman.
Crowdfunding covers various types of lending or "investing" by individuals to other individuals or businesses. I use the word "investing" lightly because in many instances individuals provide money without much reference to managing risk or maximising returns, the two hallmarks of investment.
Crowdfunding can take the form of donations and sponsorship, where individuals contribute small amounts of money to an individual or business because they like the idea or concept.
The products and ideas that do best are the novel ones which generate extensive social media comment.
