While at it, lets eliminate "online business" cause what does that mean anyway? Having no offline store? And how can you "be a website" anyway?

There are just "businesses with websites". Which is most businesses these days. Like Gap. Gap is a business with a website (their online store). So is Amazon. Should we call them different things cause Amazon has warehouses but no commercial premises? No they are both "retailers with a website". So startup should be replaced by:

"[ type of ] business with a website".

Some are software businesses, like Facebook or Google or Microsoft. Some are B2C, others are B2B. Just cause some of them choose to make digital products (software) and deliver them via a website doesn't make them a "startup" cause there are startups that make physical stuff.
