How many such companies even exist at any given point in time? In software in particular, that's going to be almost none, and those few that are, won't be that for long. For everyone else, there are already competitors doing the same thing, and even more competitors solving the same problem in a different way[0], giving you data points for roughly what prices make sense. Between that and your costs being the lower bound, you almost certainly have something to work with.
