I think the first point is probably the most differentiating characteristic. Startups are typically about innovating, doing something differently from what's expected or the norm. Typically, but not always, this leads to disruption in the domain if the startup is successful. But it should always be about innovating or attempting something different in its domain, otherwise it's just another business.
