Estimate daily active usage of Dasher App in a priority market

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.

You are asked to estimate the daily active usage of the DoorDash Dasher App in a priority suburban market. The focus is on Dashers who open or use the app on a given day to view, accept, complete, or manage delivery opportunities across food delivery, grocery, retail, and local logistics.

This is a guesstimate question, so the expected work is to define the market clearly, identify the relevant Dasher population, and build a reasonable bottom-up or top-down estimate. You should make practical assumptions about suburban demand patterns, delivery volume, Dasher supply, shift behavior, multi-apping, and how often active Dashers engage with the app.

The experience should consider:

- The geographic scope of a “priority market,” such as a suburban metro area, county cluster, or delivery zone network

- The unit being estimated: daily active Dasher App users, not orders, sessions, or registered Dashers

- Population and demand drivers, including households, restaurants, grocery stores, retail merchants, and delivery frequency

- Supply-side assumptions, such as active Dasher pool size, part-time versus full-time usage, and average deliveries per Dasher per day

- Adoption and competition effects from Uber Eats, Instacart, Grubhub, Walmart, Amazon, and local delivery fleets

- Weekday versus weekend variability, meal peaks, weather, seasonality, and local events

- Sensitivity of the estimate to key assumptions like orders per household, orders per Dasher, and percentage of registered Dashers active daily

- Sanity checks against marketplace balance, delivery reliability, Dasher earnings, and unit economics

Your goal is to produce a clear, defensible estimate with transparent assumptions, a logical calculation path, and a final daily active usage range that DoorDash could use for market planning, staffing, or product prioritization.
