The case tests both analytical skills (revenue modeling) and strategic thinking (comparing entry strategies), requiring the candidate to synthesize financial metrics (ROIC, payback period) with qualitative factors (control, cultural integration, risk).

CarPool is a new ride sharing application that connects users commuting to popular workplace destinations. Users request a ride to their selected destination and the application pools users going to the same location. The application is particularly popular in cities like Washington, D.C. and Philadelphia where access points to metro stops are more spread out. In these cities, CarPool is often seen as an efficient home-to-metro solution. CarPool customers also utilize the service on the weekend and after work for various social engagements. In cities with more extensive public transportation networks, CarPool is perceived as an alternative to taxis, buses, and other ride sharing applications. After enjoying initial success in major U.S. markets, CarPool is considering entering the U.K. market. The Company would like to know how and if they should enter the London market.

CarPool, a U.S. ride-sharing company focused on commuting and metro access, must decide whether and how to enter the London market. The case guides candidates through market sizing to estimate revenue potential (~$150M annually), then compares three entry modes. The analysis reveals that greenfield entry offers superior returns (66.7% ROIC vs. 33.3% for M&A) despite higher upfront investment, making organic expansion the recommended strategy.

Key Insights:

  1. Market sizing requires both top-down (population-based) and bottom-up (per-user behavior) approaches to validate assumptions and build confidence in estimates
  2. Entry mode evaluation should balance financial metrics (profitability, ROIC) with strategic considerations (control, cultural fit, execution risk, time to market)
  3. A greenfield strategy maximizes value in underdeveloped markets with high growth potential, though it carries greater execution and regulatory risk
  4. International expansion requires specific due diligence on regulatory environment, customer acquisition dynamics, and operational differences from home market
