Most entrepreneurs have learned that it's almost always quicker and easier to get cash from someone you know, rather than angel investors or professional venture capitalists. In fact, most investors "require" that you already have some investment from friends and family before they will even step up to the plate.
You see, investors invest in people, before they invest in ideas or products. Since they don't know you (yet), their first integrity check on you as a person is whether your friends and family believe in you strongly enough to give you seed money for your new idea. If they won't do it, they why would I as stranger invest in you?
Friends and family will likely not expect the same level of sophistication on the business model and financials as a professional investor, but they do expect to see certain things. Here is a summary of some key items to think about as an entrepreneur before approaching friends, family, or even fools:
1. Don't be afraid to ask, carefully. If you set around quietly waiting for someone you know to offer you money to fund a startup, you will probably have a long wait. On the other hand, if you open every conversation with "I need money," you won't have any friends or any money. Practice your "elevator pitch," and end it by asking for the order.
2. Be upbeat and respectful. Nothing kills everyone's optimism and desire to help quicker than a negative or arrogant attitude. If they are going to put cash into your company, chances are that they will expect to spend a fair amount of time together, either helping you or certainly discussing progress. Nobody likes a downer.
3. Be passionate about the idea. Friends and family will quickly detect your level of sincerity and thought behind the idea. You need to convince them that you have been working on this vision for a long time, and have done the "due diligence" on all the potential knockoffs. Daydreams and "the idea of the moment" won't get much respect.
