"Reinforcement: The Hidden Key to Building Iconic Tech Companies"

Interesting article from James Currier, Managing Partner at NFX:

"Every iconic company to come out of Silicon Valley in the last 25 years has done the same three things:

1. Product-market fit . “Right idea, right time
2. Rapid growth . Scale aggressively
3. Reinforcement. Build overwhelming defensibility".

NFX also provides Network Effect case studies on Uber, Facebook, and Trulia and describes how these three iconic companies continually add defensibilities throughout their life cycle.
