"Your goal = prove that the product can be sold"<p>Noooo! This makes it sound like you can start with a pricing model that is way off and change it later. When you change it, you better be charging for something different, or customers will be pissed. Netflix is perfect example. Great service, great product, and then they lost a lot of customer when they said, "Instead of paying A and getting X and Y, we're only going to give you X for A, and you can pay B for Y." If you do change pricing, you need to change the product package in a way the customer can justify.
