How would you measure product-market fit for DashPass among students

Problem Statement Description

Product context: DoorDash is a local commerce and delivery platform; its products include restaurant delivery, DashPass, grocery and retail delivery, merchant tools, and dasher tools.

DoorDash wants to understand whether DashPass has strong product-market fit among students, a segment with distinct needs around affordability, convenience, schedule variability, campus access, shared living, and budget sensitivity. DashPass may serve students across food delivery, grocery, convenience, and local commerce use cases, but the value proposition must be measured separately from general consumer subscription performance.

You are asked to define how you would measure product-market fit for DashPass among students. Focus on what “fit” should mean for this segment, how to distinguish genuine recurring value from short-term discount-driven usage, and how DoorDash should know whether the product is worth further investment, iteration, or expansion across student markets.

Your answer should be framed as a metrics problem: define the right success measures, how they are calculated, what data is needed, and how the metrics would support product and business decisions. Consider the marketplace context as well, including merchant outcomes, Dasher reliability, delivery economics, and competitive alternatives available to students.

The experience should consider:

- How to define the student population and relevant cohorts, such as verified students, campus locations, commuter students, first-time subscribers, and returning subscribers.

- What primary metric best captures product-market fit for DashPass in this segment, including the denominator and time window.

- Supporting metrics that reflect retention, order frequency, category breadth, subscription renewal, perceived savings, and engagement beyond initial promotions.

- Guardrail metrics for profitability, subsidy dependence, delivery quality, merchant ROI, Dasher experience, cancellation/refund rates, and marketplace balance.

- Instrumentation needed to connect student identity, subscription status, order behavior, campus geography, offer exposure, and renewal behavior.

- How to separate product-market fit from seasonal effects such as move-in periods, finals, holidays, summer breaks, and graduation.

- How to compare cohorts across campuses, city density, competitive intensity, and available merchant selection.

- How the metrics would inform decisions such as pricing, student-specific benefits, campus expansion, marketing investment, or product changes.

The goal is to evaluate whether DashPass is becoming a durable, valued subscription product for students—not just whether students try it once. Your measurement approach should help DoorDash determine if students repeatedly rely on DashPass, receive clear value, and can be served in a way that is sustainable for the broader marketplace.
