# Invest in Closed-Loop Data Systems

**Action.** Direct strategic funding toward [[concept-data-flywheels|Type 4]] investments: closed-loop operational systems where **proprietary data feeds back into the AI model**.

**Rationale.** Evaluate these on their **compounding rate** (how fast the AI improves per cycle of operational data) and the **depth of customer lock-in** they create — not current output. Note the open measurement problem in [[question-measuring-flywheel-velocity]].

**Outcome.** Creates high customer switching costs and durable competitive advantage (the John Deere pattern — [[entity-john-deere]]).
