Figure out who your ideal customer is and make sure your product fulfills that customer's needs. Be really specific about that, not just "project manager", but include age, marital status, hobbies, etc so you really get to know this person. You want to be able to know them so intimately that you could conceivably introduce them to a friend at a social gathering. The point here is to get into the mindset of the users of your product. What are you enabling them to do, how do they want to interact with it, and how much are they willing to pay for the service. You'll want 2-3 ideal customers to start off with to cover your target market. Once you have an idea of who that is, find them. You already know them well enough to know where they would be found, right?
