> Just because the company uses AI doesn't make it an "AI startup."

I think you need to expand a bit more this. I does sound to me that if you are using AI in the main product you are an AI startup.

It is similar with if you are offering a web version of your app you are an internet company. And if you are offering a mobile version you are a mobile company.

and a company can be more than one: An internet AI mobile company :)
