After inventing a product, one of the most difficult things an inventor has to do is to come up with the money to fund the development of their invention. For most inventors, raising money is a scary proposition. Where do I get the money? What is an angel investor? Do I need a business plan? How much money will I actually need to get my invention made? Most people seem to have a very general idea of what to do but when it comes down to it they simply do not know how to raise the money they need.
