I agree that the labels Paul used already carry meaning that confuses what I think Paul is really trying to point out. I also agree that it's really hard to tell whether someone is capable of leading in "founder mode", and to what degree.

Ray Dalio describes these people as "Shapers", and maybe using a new term is the right way to go.

So putting this term to work, Paul's point is that the best way to run a company when the leader is a shaper isn't going to be the same as when the leader isn't a shaper. And to your point not all founders are Shapers and not all Shapers are founders.
