Good question. I reckon the answer is mixed: some customers are individuals -- where the person who decides to make the purchase is the end user -- some customers are small businesses, while some customers are enterprises. It does appear to have some business & enterprise functionality - at least around how license management works (having some people with permission to manage a pool of licenses for the software that can be granted or withdrawn to individual users in an org). I wonder what fraction of intellij's customers are individuals, small businesses, vs enterprises. My hypothesis is that software that is sold to individuals, where the purchaser is the same as the end user, has more evolutionary pressure not to be awful.
It'd be interesting to ask "what is the best enterprise software you use that is ONLY sold to enterprise customers and never to individuals" as there's more pressure on such software not to be usable.
