It used to be that if you were an entrepreneur looking to fund a new project, you had a few choices. There was the bank, private investors or your family to provide money to launch a project. But now, people are turning to crowdfunding sites like Kickstarter as an alternative. Entrepreneurs can pitch their products, some that aren't even made yet, in exchange for financial backing.
