Lion King Bank is a consumer bank in South Africa providing checking, savings, credit cards, loans, etc. They have branches in all 9 South African provinces. They have completed an aggressive cost-cutting program, but revenues are still low and profitability is also low. They are looking to fix this and improve profitability quickly, and they’ve come to us to help them find a solution

Clarifying Information

  1. Nothing has changed about the competitive landscape recently. Direct that candidate away from this area if they keep asking questions about it.
  2. The sample framework to the right is JUST a sample. A candidate can come up with something radically different if it is structured, logical, and relevant.

Lion King Bank seeks to improve profitability after cost-cutting measures. The case explores whether to target high-growth student accounts or affluent mid-income customers, ultimately recommending the latter given the 2-year revenue growth imperative.

Key Insights:

  1. Aligning strategy with timeline and business objectives—student accounts grow 7-8x but generate minimal fees; mid-income customers drive immediate revenue
  2. Customer lifetime value (LTV) differs significantly by segment—students have high future potential but low current monetization; affluent customers monetize immediately
  3. Revenue drivers decompose into account quantity and revenue-per-account; prioritization depends on which lever the business can pull fastest given constraints
  4. Long-term customer value (student switching costs) must be balanced against short-term performance targets, requiring explicit risk acknowledgment
