I strongly disagree that being data-driven and collecting a lot of data is directly correlated with disregarding user privacy. You can collect a lot of data on how customers interact with your product without associating any of this data with a specific customer. And also the goal of being data-driven is not to scale fast. The goal is to validate your features are meeting the assumptions and expectations while providing customers with as much value as possible.

We intentionally focused the article on 1 to 100. Today we are over 400 engineers and we are still pretty happy with how the engineering velocity progressed as the team grew.

I completely agree that it is not possible to maintain the same velocity. I have always optimized to decrease velocity as little as possible as you scale the team. That you really want to avoid is doubling your team and your velocity dropping by 50% or more.

Ideally you double you team and velocity decreases by 10-15%.

This photo was the whole company at the end of 2018!

Engineering at that time was about 20 or so people.
