I generally subscribe to PG's definition of a startup, which is a company designed to grow fast: http://www.paulgraham.com/growth.html

I prefer Steve Blank's, an organization in search of a repeatable and scalable business model. See https://steveblank.com/2010/01/25/whats-a-startup-first-prin... for more.

The two definitions are equivalent though.
