Customer Health Score for FinTech at Series B

Ehsan's Analysis

FinTech customer health should measure financial engagement depth, not product engagement breadth. A neobank customer who logs in daily to check their balance but only uses checking has lower financial health (and lower LTV) than a customer who logs in monthly but uses checking, savings, investment, and credit products. The FinTech health score formula: (products actively used × average balance per product × transaction frequency). Nubank reportedly uses a similar metric and segments customers into "engaged" (3+ products, growing balances) and "dormant" (1 product, declining balance). The engaged segment has 2% annual churn and $100+ annual revenue. The dormant segment has 25% annual churn and $15 annual revenue. The health score is not just predictive — it defines the retention strategy. Engaged customers need self-serve tools. Dormant customers need proactive outreach with a cross-sell offer tied to a specific financial need.
