What you are actually choosing between

Founder OS is not the only way to spend this budget, and pretending otherwise wastes your time. Each comparison below states the real structural difference and names the cases where the alternative wins.

How these are written

A comparison page written by the vendor is worth reading only if it can say where the vendor loses.

Every comparison carries a “when the alternative is the better choice” section. It is not a formality — if one of those cases is yours, buy the other thing.
Claims about other products describe their publicly documented behaviour. Where something is genuinely a matter of fit rather than capability, it is described that way.
No performance numbers, time-saved percentages or customer counts appear anywhere on this site, because none have been measured. The case studies are labelled illustrative for the same reason.
Founder OS features are stated at their real status — Obsidian and Google Calendar are live, Notion is in progress.
