"Revenue is growing, but customers are leaving"
Lemur Media · author: Dominik Dębski · updated 28.10.2026
Growth based on winning new customers can hide the loss of existing ones. Without cohort retention analysis, the problem becomes visible only when sales slow down. The solution is a Revenue Engine Map with an owner for retention and expansion.
What are the symptoms?
- Revenue growth comes almost entirely from new customers.
- The company does not track Net Revenue Retention, or the figure is below 100%.
- Sales promises features the product does not have.
- Onboarding a new customer takes a long time and does not end with confirmation that the goal was achieved.
What are the causes?
- 01No cohort analysisMonthly averages do not show that each new cohort churns faster.
- 02Activation without an ownerNobody is responsible for whether the customer reaches first value.
- 03No expansion pathThe offering does not allow the contract to grow as the customer grows.
| Headcount | Typical picture |
|---|---|
| 1–49 employees | The cause is usually a poor product fit for some customers. |
| 50–249 employees | The cause is usually activation and post-sale service. |
What questions should the board ask?
- What share of customers from each cohort remains after 12 months?
- How much time passes from contract signature to the first confirmed result for the customer?
- What share of revenue comes from contract expansions?
Which metrics should you check?
- Net Revenue Retention
- Cohort retention after 3, 6 and 12 months
- Time to first value
Which mistakes should you avoid?
- Increasing the acquisition budget before identifying why customers leave.
- Retention discounts without analysing the reasons for cancellation.
