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 with students, a segment that may have distinct needs around affordability, campus access, late-night ordering, group meals, grocery/convenience use cases, and seasonal behavior tied to academic calendars. The question is not simply whether students subscribe, but whether DashPass meaningfully solves recurring student needs in a way that creates durable engagement and sustainable marketplace value.

Frame this as a metrics interview focused on defining how DoorDash should measure product-market fit for DashPass among students. Your answer should clarify who counts as a student, what behaviors indicate genuine fit versus one-time discount-driven usage, and how the measurement approach should account for the multi-sided marketplace involving consumers, merchants, and Dashers.

The experience should consider:

- A clear definition of the student segment, including eligibility, verification, geography, campus proximity, and lifecycle status such as freshman, graduate student, commuter, or international student.

- Metric definitions that distinguish acquisition, activation, retention, frequency, subscription renewal, order mix, and willingness to keep paying after promotions expire.

- Appropriate denominators, such as verified students exposed to DashPass, students who start a trial, active subscribers, eligible campus-area users, or retained cohorts.

- Instrumentation needed to connect student identity, DashPass enrollment, order behavior, savings realized, delivery reliability, merchant availability, and cancellation reasons.

- Cohort cuts by school type, city density, dining options, seasonality, promotion exposure, order category, and campus delivery constraints.

- Guardrail metrics for marketplace health, including delivery quality, merchant ROI, Dasher earnings, support contacts, refunds, and unit economics.

- How to separate true product-market fit from short-term subsidy effects, exam-week spikes, move-in periods, or temporary marketing campaigns.

- How the metrics would inform decisions such as expanding the student offer, changing pricing, improving campus delivery coverage, or investing in specific use cases like late-night meals or convenience orders.

The goal is to describe a measurement framework that helps DoorDash decide whether DashPass is becoming a must-have product for students, where it is working or failing, and what evidence would justify further investment in the segment.
