Havercroft, who said the company was now worth $3.5 billion, said he would continue as an advisor to the board of the company which controls a vast library of corporate training videos.

It follows the recent $100 million deal to buy German company Blinklist, which provides a 15-minute summary of books.

The company is expanding quickly and Havercroft said revenue was now in the hundreds of millions and the value had gone from $1 billion to $3.5 billion.

“We have matured from a start-up to a scale-up. I can’t wait to see the next evolution and the next chapter written as I hand back to the founders new and old,” he said.

“For me, it’s time for some rest and reflection. I’m looking forward to finally having time for those overdue and new connections and letting the gods of timing and opportunity do their thing.

“The terms ‘scalable and repeatable, do the basics brilliantly’, have become the day-to-day, and the privilege of leading this fine group of humans has encompassed exactly that, and I thank my team and each one of the Go1 tribe globally for that privilege.”
