A good article generally but I'm tiring of attempts to narrow the definition of "startup" to meaning an extremely high growth, unprofitable business. That's a type of startup and while those types of startup are common in this community, it's a myopic definition in general.
A startup is simply a company trying to get off the ground. Once it is established with customers, a product and a stable source of revenue, no matter how small (or big) it is or how much growth it is experiencing, it is no longer a startup. It is an established company.
Frankly, I don't understand people who try to widen the definition of startups to include nearly every non-public company on the planet.
If you're sick of hearing of "high growth" as the only type of startup... why not point out some examples that you think better fit the term?
Here's a freebee: Steve Blank's startup definition is that a company is searching for a business model, and when it's found the model, it is no longer a startup.
