Quora: What's the right time to create a growth team?
My answer:
[…] Growth engineering is about consistent small gains, with some big wins mixed in for good effect. To achieve this is a matter of patience, discipline and a keen (but flexible) understanding of your product and market. When you’ve achieved product/market fit, you know why, and you have a stream of data to work with, you’re ready.
