What I wonder is if this would be very useful to someone trying to start a software business that they don't want to turn into a 'startup' in the sense it's generally used here (not trying to become a billion dollar company or even seeking investment at all). It seems like best advice and strategies for those routes have some overlap, but also a lot of points where good advice for one is bad advice for the other.
