For every Facebook, Amazon, Apple, Netflix and Google, there are literally thousands of small start-ups trying to 'scale up' to become the next Slack, Zoom or Uber. Less than 1% of these start-ups will be able to scale up. For the would-be entrepreneurial leader, for employees working in a start-up, for a potential investor, how to tell if the business-in-the-back-bedroom will ever see its name in lights?

A commonality among these companies is, firstly, their relatively short organizational life span to-date (they are often only now about 10-15 years old) and secondly, the speed in which they have grown into multi-billion-dollar organizations.
