Case · 8 minutes
A fictional D2C team has ₹10 lakh and needs the cohort to recover acquisition spend within 90 days. Recommend an allocation and state what evidence you’d require before scaling.
- Search: ₹4,00,000 for 1,200 incremental customers at ₹410 contribution each. Spend cap ₹5,50,000.
- Paid social: ₹4,00,000 for 1,500 incremental customers at ₹280 contribution each. Spend cap ₹6,00,000.
- Creators: ₹2,00,000 for 650 incremental customers at ₹350 contribution each. Spend cap ₹3,50,000.
Incremental CAC rises by 50% above each channel’s baseline spend.
