Scenario
Amber Grid is a mature-stage utilities business in Europe. The CMO has €140 M of annual acquisition budget and has been asked to justify next year's plan.
Last year's spend and results:
| Channel | Spend | New customers | Cost per acquisition |
|---|---|---|---|
| Paid search — non-brand | €57 M | 2,650 | €21509 |
| Paid search — brand | €8 M | 2,561 | €3124 |
| Paid social | €49 M | 812 | €60345 |
| Affiliates & retargeting | €26 M | 999 | €26026 |
Unit economics:
- Average revenue per user: €1277 per month
- Gross margin: 56%
- Monthly churn: 4.9%
The board has asked for a 35% increase in new customers next year without an increase in budget. The CMO's instinct is to move money into brand search, which shows by far the lowest cost per acquisition.

Your task
Recommend an allocation. Your answer should provide:
- Analysis — the unit economics and each channel's true efficiency, computed rather than described.
- Risks — what your reallocation depends on, and what would change your mind.
- Recommendation — a specific budget shift, and how you would prove it works before committing fully.
State any assumptions you make.
