Suppose you have an idea that you think could change the world, and bring you and your partners a lot of money at the same time. So you start a company based around that idea and develop your product further. But after some time you realize that as much as the company is yours and you are willing to work on it till the world’s end, you alone don’t have the resources to give a proper physical form to your idea. So instead of feeling dejected and giving up, you bring in a person who has the resources to bail you out of your fix. This person is called an Angel Investor.
