Lesson 1 — What a Money Operating System Actually Is
Before you compare a single platform, you need a frame to hang it on. This first free lesson explains what a money operating system is, why we organize by function instead of brand, and how the rest of the Classroom builds on it.

Lesson 2 — Organize by Function, Not by Brand
Ranking apps by brand tells you who won this quarter. Tagging them by function tells you what job each one does and whether that job has a backup. This lesson shows you how to run the tagging pass on your own accounts.

Lesson 3 — Custody: Who Actually Holds the Asset
Two venues can look completely separate on the surface and still collapse together, because the same custodian sits underneath both. This lesson explains custody types so your redundancy is real and not just cosmetic.

Lesson 4 — The Redundancy-First Rule and a Review Cadence
The final free lesson turns the map into a rule you can operate: at least two independent venues per critical function, a concentration cap, and a recurring review so the system stays honest as rates and terms change.
