Eric Ries' definition is: A startup is a human institution designed to deliver a new product or service under conditions of extreme uncertainty
And Steven Blank's [3] definition is: A startup is an organization formed to search for a repeatable and scalable business model
With these different definitions, I ask: which definition of a startup, NOT limited to these 3, most accurately reflects, in your opinion, what a startup is?
