Quantile Capital: Every Channel Claims the Same Sale
Marketing
medium40 min0 submissionsBCG
Scenario
Quantile Capital sells asset management in UK. Last quarter it spent £69 M across three channels: brand (30%), paid search (34%) and paid social (36%).
The company recorded 6,973 conversions. Added together, the channel dashboards claim 12,970 — about 1.86x the real number.
Paid search reports the best return and the search team wants more budget. Brand reports the worst and is under pressure to justify itself. Attribution is last-click. Nobody has run a holdout test.

Your task
Advise the CMO. Your answer should provide:
- Analysis — what the reported numbers can and cannot tell you, quantified.
- Risks — what happens if you reallocate on last-click alone.
- Recommendation — a budget decision and the experiment that would prove it.
State any assumptions you make.

Hint
Reveal suggested structure
Separate correlation from incrementality. Last-click credits the final touch; demand generation appears worthless under it. Design a holdout before reallocating.
