For subscription businesses
Add subscribers in the neighbourhoods where they stay
Scaling a subscription is a bet on geography: acquisition earns back only where likely subscribers are dense enough, and margin holds only where they stay. Spread spend across areas that were never dense enough, or win members in neighbourhoods that churn, and the model quietly leaks. IRIS reads where your likely subscribers cluster and where retention is easiest to defend, so you grow on evidence instead of instinct.
