Cut churn or buy more customers?
New to this industry?Start with its one-minute summary: Restaurants and food service
The prompt
The fictional meal kit company wins 10,000 new customers a month and loses 8 percent of its customers each month. Each customer brings SGD 36 of contribution a month. Option A: a better first month (free menu changes, a call from a chef) cuts churn to 6 percent and costs SGD 200,000 a month. Option B: more advertising raises new customers by 25 percent at a cost of SGD 150 for each extra customer. Which option earns more once the customer base settles? (Assume churn stays steady.)
