Companies and organisations that are just starting out or setting up always need a financial boost to get things going. If your idea is untested and you are not prepared with business plans and polished pitchs which are needed for an angel or venture capitalists then using a crowdfunding site is ideal for you.
Crowdfunding is where you get a lot of people (the crowd) to support your idea, rather than finding one person to come up with everything you need, the crowd support you by contributing small amounts because they like your idea and want you to succeed.
There isn't any equity or stake in the business or venture on offer, just a way for people to help you make your dream or project turn into a success.
Here are some of the popular sites out there:
This is one of the best known, it has a large base of followers and has helped raise $millions of dollars.
This is a niche funding site aimed at artists and the creative sector.

Another great site
Does what it says on the tin, crowdfunds for businesses based in the UK.
All these are well worth investigate and trying.
