Many entrepreneurs turn to friends and family for their first funding needs. In fact, it is common for non-tech startups to raise all the capital they need from friends and family. I don't know for sure, but I would suspect that friends and family make up the largest source of funding for entrepreneurs and startups.
Friends and family financing is popular because it is easy to get a hearing from the people who know you best and they are positively inclined to say yes. But there are some negatives as well.
