Summary

Google product case question about estimating incremental revenue from expanding a food delivery app into a new vertical. Pretty lean on context but the core of the question is a market sizing and monetization exercise.

Q1

How would you estimate the incremental revenue a food delivery company could generate by expanding into a new vertical?

Author's notes

I went straight into sizing the addressable market for the new vertical and tried to break down revenue by attach rate and average order value.

Suggested Approach

Start by clarifying the scope: which new vertical, target market, and time frame. Then structure your answer by estimating the total addressable market for that vertical, the company's expected market share, and the incremental revenue per user, adjusting for cannibalization and costs. Use a top-down and bottom-up approach to triangulate a reasonable estimate.

Pro tip: Show that you understand the difference between gross and incremental revenue by explicitly discussing cannibalization and the cost to serve; this demonstrates strategic maturity and avoids overestimating the opportunity.

1. Clarify the scope

Ask clarifying questions to define the new vertical (e.g., grocery, pharmacy), target geography, time horizon, and whether we're estimating revenue for the entire company or a specific product line.

2. Size the market

Estimate the Total Addressable Market (TAM) for the new vertical using top-down (industry reports) and bottom-up (number of potential users × average order value × frequency) methods.

3. Estimate market share

Determine a realistic market share the company could capture based on competitive landscape, existing user base, and operational capabilities. Consider ramp-up over time.

4. Calculate incremental revenue

Multiply market share by TAM to get gross revenue, then adjust for cannibalization of existing verticals and incremental costs to arrive at net incremental revenue.

5. Sanity check and iterate

Validate assumptions with benchmarks, sensitivity analysis, and compare against analogous expansions. Present a range rather than a single number.

Key Points to Mention

  • Total Addressable Market (TAM) and Serviceable Obtainable Market (SOM)
  • Cannibalization of existing offerings and net incremental revenue
  • Customer acquisition cost (CAC) and lifetime value (LTV) for the new vertical
  • Operational feasibility and cost to serve (e.g., logistics, partnerships)
  • Competitive landscape and differentiation
  • Sensitivity analysis and scenario planning (best case, worst case, most likely)
