Our client is Lactose King, a premium ice cream restaurant chain with approximately 3,000 locations throughout the United States. While they’ve enjoyed consistent profitability and are an industry leader in direct-to-consumer ice cream sales, their revenue has been stagnant over the past few years. What can they do to improve their gross revenue?

Clarifying Information

  1. Lactose King operates under a simple business model of owning and operating all of their own stores, procuring ingredients from various suppliers throughout the country, and processing/serving the ice cream at individual locations.
  2. They serve only soft-serve ice cream and related products (milkshakes, ice cream sandwiches, etc.)
  3. Revenue last year was at $250K/store [$750M], and they would like to improve gross revenue by 33% in 1 year [$1B target].
  4. The candidate’s framework should consider: improving ice cream sales (marketing campaign, expanding outside of the United States), offering a new product (desert or non-desert), utilizing a new sales channel (selling to grocery stores), consumer preferences, etc.

Lactose King, a 3,000-location premium ice cream chain, needs to increase revenue by 33% ($250M) from $750M to $1B within one year. Through demographic analysis, candidates identify the 18-32 year-old market as the highest-potential segment, discover that low-calorie options are underserved despite high importance to this demographic, and recommend introducing a sugar-free ice cream product that would generate $400M in net revenue while accounting for 33% cannibalization of existing sales.

Key Insights:

  1. Market segmentation by demographic is critical—the 18-32 age group offers the best combination of market size, LK market penetration, and market fragmentation
  2. Customer needs analysis (Exhibit #2) reveals a gap between importance (low-calorie is highly valued) and LK’s current performance (underperforming on low-calorie offerings)
  3. Cannibalization must be modeled explicitly—the recommendation accounts for 33% cannibalization but the net $400M revenue still exceeds the $250M target
  4. Quantitative rigor is essential: candidates must calculate total addressable market size and work backward from the $1B revenue target to validate feasibility
