Six-Month Scorecard for a Super-App's New Peer-to-Peer Car Rental Marketplace

A super-app such as Grab is adding a new vertical: peer-to-peer car rental, where people rent their own cars out to other users. Which metrics would you track over its first six months to judge whether this vertical has real potential? ```hint Two sides, one place and time A rental only happens when a listed car and a willing renter meet in the same area and the same time window. Ask which numbers show each side growing, and which show that the two sides are actually finding each other. ``` ### Clarifying Questions - Is the vertical launching in a single city or in several of the super-app's markets at once? - Can only private car owners list, or may small rental fleets list cars as well? - Who carries insurance and handles damage claims: the platform, the car owner or the renter? - At the six-month mark, is leadership deciding whether to keep investing at all, or setting growth targets for a vertical it has already committed to? ### What a Strong Answer Covers - A clear definition of what "potential" means at six months, and a north-star metric suited to an early two-sided marketplace - Separate funnels for car owners and for renters, plus measures of whether the two sides match locally - Trust and safety guardrails specific to handing a private car to a stranger - Early unit-economics and incentive signals, read without mistaking subsidized growth for real demand - How the vertical interacts with the rest of the super-app, including cross-use and cannibalization of ride-hailing ### Follow-up Questions - Car utilization is rising, yet owners are removing their cars from the platform faster each month. What could explain this, and what would you check first? - How would you tell whether car rental is pulling riders away from the app's ride-hailing service? - If you could show leadership only one chart at month six, which would it be and why?
