> with 3 developers

There is a fairly large chasm between a small team and a Shopify, AirBnB, or Udacity. These companies have dozens-if-not-hundreds of developers piling on complexity.

These companies don't necessarily feel the pain of building on somebody else's sand on day 1 or day 100, but on day 1000. This is what AirBnB and Udacity ultimately discovered.
