Evaluate a Credit Card Partnership

You are a Product Manager evaluating a Capital One credit-card partnership with a merchant such as Uber. The business goal is to increase engagement and drive more card spend. Assume three user segments: - Segment 1: 100,000 users. Merchant spend before/after = `$0 / $0`. Card spend before/after = `$200 / $200`. - Segment 2: 50,000 users. Merchant spend before/after = `$10 / $20`. Card spend before/after = `$400 / $410`. - Segment 3: 50,000 users. Merchant spend before/after = `$0 / $40`. Card spend before/after = `$300 / $500`. Capital One earns 1% margin on card spend and pays for a 20% discount at the partner merchant. Answer: 1. Is the partnership directly profitable? 2. If not, why might the company still do it? 3. If each customer generates $300 of value to other Capital One business lines, how many additional valuable customers are needed to break even? 4. What would you recommend? ### Constraints & Assumptions - State whether the 20% discount applies to all post-launch merchant spend or only incremental/eligible spend. - Calculate incremental card margin and discount cost by segment. - Distinguish direct profitability from strategic lifetime value. - Consider targeting, caps, merchant co-funding, and abuse risk. ### Clarifying Questions to Ask - Who funds the discount: Capital One, the merchant, or both? - Is the discount applied to all merchant spend or only incremental spend? - Are card-spend values per month, per campaign, or over a fixed period? - Does the partnership acquire new customers, retain existing customers, or shift existing spend? - What fraud, redemption, or cannibalization risks exist? ### What a Strong Answer Covers - Correct direct P&L math by segment. - Explanation of why direct loss may still be acceptable strategically. - Break-even customer calculation using $300 cross-business value. - Recommendation to target high-incrementality segments and test before broad launch. - Guardrails for margin, spend lift, retention, abuse, and customer experience. ### Follow-up Questions - How would you estimate incrementality? - Which segment should receive the offer? - How would you design a pilot? - What if the merchant agrees to co-fund half the discount?
