The gap
Revenue looked healthy; the cohorts didn't. Subscribers churned hard at month 3, and the only "retention" running was a 20%-off blast every Friday — training customers to wait for discounts.
What we ran
- AI cohort audit priced the month-3 churn cliff at $46k/mo
- Churn-save flow: pause/swap offers before cancellation, not after
- Post-purchase education series tied to the product's 90-day results window
- Win-back at day 75, triggered by purchase-interval data, not a calendar
- Retired the Friday blast; campaigns moved to a value-led calendar
The result
Email & SMS went from 18% to 43% of total revenue in 9 months — while total sends dropped 22%. Less noise, more money.

“Kairos found six figures hiding in a win-back window we didn't know existed. The audit paid for the year in the first month.”
