Nutrafol × AYMI

Nutrafol's acquisition machine was working. New-subscriber growth was healthy. But cohort retention — the metric that turns a subscription business into a compounding one — was leaking somewhere between month two and month four, the window before efficacy results become visible to the customer.

Pouring more spend at the top wasn't the answer. The brief was to find and seal the leaks across product education, lifecycle communication, and offer architecture — and prove it in cohort retention curves, not vanity metrics.

Five movements: Discovery, Strategy, Creative, Launch, Optimize. Each one feeds the next; the loop closes on Optimize and starts again on Discovery.

1. Step 01Discovery

   Cohort-level retention diagnostic across 24 months of subscription data. Identified two leak points — early-window doubt and mid-window plateau — neither addressed by existing comms.

2. Step 02Strategy

   Retention plan organized around the customer's journey to “first felt result” — not around marketing's calendar.

3. Step 03Creative

   Lifecycle redesign: progress check-ins, science-backed education modules, dermatologist testimonial set. Editorial wellness register, not promotional.

4. Step 04Launch

   New lifecycle program rolled out across cohort segments. Concurrent paid retention layer (suppression on cancelers, conditional offers on at-risk cohorts).

5. Step 05Optimize

   Cohort-curve reviews monthly. Lifecycle modules iterated as the early-window leak began to close.

Recurring revenue lifted 320% over eighteen months — almost entirely from retention gains, not from new-subscriber surge. Retention rose 58%. Marketing ROI hit 4.2× as the spend mix tilted toward retention. LTV per cohort climbed 44% and cancel rate at month three dropped 28%.

Nutrafol's growth model now plans retention as a primary spend surface, not a downstream consequence.
