“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.

“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.”
