There isn't necessarily a right way to do it. I would say that if you are trying to figure out what to do as a start up and where to start the most important thing to do is start. If you can get 80% of the way there then often times that remaining 20%, lets say that remaining 20% is the gap between where your at and a perfect answer, a perfect product, a perfect sales pitch. Often times that 20% is more of a nice to have then the 80% of actually having something there.
