That's what startup originally means. The term is watered down, but startup = growth and big failure rate.

Startup is not same as new company or new tech company.

> A startup is a company designed to grow fast. Being newly founded does not in itself make a company a startup. Nor is it necessary for a startup to work on technology, or take venture funding, or have some sort of "exit." The only essential thing is growth. Everything else we associate with startups follows from growth.

The OED keeps track of original usage. Here's the entry:

orig. U.S. A business or enterprise that is in the process of starting up, or that has just been established; a startup company, venture, etc.

They cite these early usages in print:

1975 Chicago Defender 20 Sept. 23/1 The many problems faced by any new start up, but most assuredly by a black financial institution.

1986 Your Business Mar. 11/3 There are the small businesses; the heroic little start-ups in their garages and garden sheds.
