Capital One Product Strategy: The Business Case for Mobile Banking App Engagement

You are a product manager at Capital One, the US bank and credit card issuer. The interviewer asks you to explain how a customer who uses Capital One's mobile app is valuable to the company. Describe the different ways that value shows up, which of them you think matter most, and how you would measure them. ```hint Translate usage into economics Checking a balance is not value in itself. Ask how app use changes the bank's numbers for that customer: what they earn the bank, what they cost to serve, how long they stay, and how much risk they carry. Then ask whether the app causes those changes or simply attracts customers who were already more valuable. ``` ### Clarifying Questions - Which customers should I focus on: credit card holders, checking and savings customers, auto loan borrowers, or small business customers? - Should value be measured as the customer's total worth, or as the extra value compared with a similar customer who does not use the app? - Do you want a map of every source of value, or should I also recommend which one the app team should push hardest? - Which time horizon matters: this year's profit, or value over the customer's whole relationship with the bank? ### What a Strong Answer Covers - Sources of value tied to Capital One's actual businesses, such as card spending and balances, deposits and lending, rather than generic "engagement" - Lower cost to serve through self-service, with the mechanism spelled out - Retention, cross-selling and risk effects, including credit losses and fraud - A measurement approach that separates the app's causal effect from the fact that more engaged customers choose to use the app - Where the bank's value and the customer's interest conflict, and the costs and risks the app adds ### Follow-up Questions - Your data shows app users are far more valuable than non-users. How would you work out how much of that gap the app itself caused? - If you could fund one new app feature to grow this value, which source of value would it target, and why? - A feature such as payment reminders helps customers but reduces fee revenue. How would you decide whether to ship it?
