Northwind Energy: Is the Growth Worth What It Costs?
Marketing
medium35 min0 submissionsBain
Scenario
Northwind Energy sells renewables subscriptions in Europe. Growth has been strong and the board has asked whether it is profitable growth.
Marketing spends €30 M a month and acquires about 3,445 new customers in that time. Average revenue per user is €1129 a month at a 83% gross margin. Monthly logo churn runs at 4.7%.
Roughly 80% of new customers come through paid channels; the rest arrive organically but are counted in the same blended figure. The CMO reports a healthy LTV/CAC and wants to double the budget.

Hint
Reveal suggested structure
CAC = spend / customers acquired. LTV = ARPU x gross margin x 1/churn. Judge on payback period and on unblended channel economics.
