What defines a startup for me is utilizing technology with a very good chance it will be a spectacular failure. You have a great feeling that you'll have users but there's a very real chance that you'll get none to 10 and go down in tremendous flames. You're swinging for the fences. That's because you're doing something that no one has done or your entering a market with huge dominant players whom you hope to usurp. It's either very audacious or insane. Your 10 professional friends split down the middle when asked. You know if you open a barber shop you will get people come in off the street to cut their hair. You just worry you'll have enough over time to sustain it. If you start a consulting business you know you'll get clients (at least I assume you do) as your skills are in demand. You probably got commitments from at least 3 before you made the plunge. It's just whether you'll get enough and a steady flow to go with. If you're bootstrapping a lifestyle tech company it's probably because you know exactly what the market needs and have your first 5 customers from your previous gig so you know you can get through the first year. All of these still have a large amount of risk but they're not really true startups to me. It's true it's very hard to have a startup without (rapid) growth as the central tenant . And you can have many businesses that are not startups that aren't focused on growth over anything else. However, you can have many businesses that are not startups hyper focused on growth (SuperCuts, Pappa Johns) to make the definition in this essay too weak for me.
