Growth needs culture, not just experiments

What a great growth engine and a great growth team is one that where you set the culture, set very simple north star metrics, usually one, at most two. And you've created a culture of defining hypotheses that are data driven and a culture where that can be executed quickly and have an MVP mentality for product and non-product projects where people can fail and learn quickly and iterate quickly.

When you build a growth team and you hire the right growth leader, they start asking all the right questions because when the archetype of person who is a growth PM will be like, 'Well, wait. Why is this happening? And let's get the data on X, Y and Z thing.'

Unless you have at least tens of thousands of users, the math, the statistics just don't work out for most of the metrics that you're interested in. Start experimenting when you're in the tens of thousands of users. Below that, start building the culture, start building the platform, start integrating.

The challenge with being a product manager is, everybody thinks they can do the job. The moment you build experimentation, you've now made it scientific.
