In all the debate this comment spawned, I think people need to realize that we need some language to clearly distinguish between big business, small business, and what I'll call "startups" here. I think "entrepreneur" is a good word to cover small business, including that local pub or barbershop. Such businesses have linear growth and a low ceiling. Software startups can have exponential growth and a ceiling orders of magnitude higher. An entrepreneurial small business could be very successful at a million dollars of revenue. An equivalent level of success in startups is a billion dollars.

So "startup" as a subset of "entrepreneur" seems like good language to me. The difference is the opportunity for exponential growth.
