I can start a business without an investment round, but not a startup? Is it a startup if it involves tech, a business if not? What if they use SOME tech, but not necessarily innovative tech? Or is this one of those 'you know it when you see it' kind of things? Has the term startup become a buzzword like "optimize" or "synergy"?
Seriously asking, not being snarky.
edit: thank you, for the responses that clarifiesthe distinction
