Growth spend was outrunning retention.
This marketing & margin audit surfaced $51k in recurring annual margin in a Subscription business — evidenced, senior-reviewed, and delivered in 5 days.
The business
A subscription media business had strong day-one acquisition numbers and reported them with justified pride, using healthy sign-up volumes to make the case for scaling spend. The front door was clearly working, and because so much attention went to the impressive top-of-funnel figures, the back door — where subscribers quietly left — got far less scrutiny than it deserved.
What triggered the audit
Revenue growth persistently lagged subscriber growth, a divergence that almost always means the back door is as busy as the front. Rather than stopping at the flattering acquisition numbers, the audit followed cohorts well past the honeymoon period into month three and beyond, where the real durability of a subscription base either holds or gives way.
What the audit found
The impressive acquisition numbers were masking a retention problem serious enough to undermine the whole model. Cohorts started strong but churned heavily by around month three, so most of the value implied by day-one sign-ups had evaporated well before it could compound. Growth spend was effectively outrunning retention: the business kept pouring new subscribers into the top while a comparable stream drained out the bottom, and on recent cohorts the lifetime value no longer covered the cost of acquisition at all. Because leadership steered by acquisition metrics, the deterioration in cohort economics stayed invisible until the audit put retention and CAC side by side, revealing an LTV:CAC that had quietly slipped underwater on the newest, largest cohorts.
What we changed
Rebalanced budget out of raw acquisition and into onboarding and early-life retention, fixing the leak in the base before pouring in yet more new subscribers.
Held new-cohort acquisition spend to the level the current retention curve can genuinely sustain, ending the dynamic where growth persistently outran retention.
Made cohort LTV:CAC the pacing metric for the whole business, so acquisition can no longer scale faster than the ability to actually keep customers.
Targeted the specific month-three drop-off with retention interventions, addressing the churn precisely where the data showed it was happening.
The result
LTV:CAC improved 22% by fixing the leak before adding more water. Any subscription leader should feel this one: strong day-one sign-ups masked heavy month-three churn, and steering by acquisition metrics kept the deterioration invisible. If your revenue growth lags your subscriber growth, the back door is as busy as the front — and every new cohort funded on that gap loses money quietly. It takes cohort analysis past the honeymoon to see it. A fixed-fee audit surfaces it in days, while there’s still time to fix retention first.
From kickoff to signed-off findings: 5 days — inside our fixed 5–7 day window.
This +22% LTV:CAC gain is ≈$51k/yr at the client’s revenue scale.
