A Kestrel challenge · 115 days

Allocate a finite acquisition budget

Compare channel reach at different budgets and setup speeds. Account for saturation and the remaining delivery window before scaling expenditure. The provider is adding an expensive observability product to a popular analytics base. A new segment may pay more but also requires higher service guarantees. Keep at least 45% of opening paid customers through the closing window. Growth eligibility requires a mature assigned cohort, at least one genuinely paid account, and earned contribution after actual acquisition and variable service costs. No free-form pitch is scored.
