We recommend making a marketplace's first transaction small enough to observe: one neighborhood, service window, or event. Choose supply or demand based on the constraint, fulfill a small batch manually when necessary, calculate capacity from actual work, make a narrowly scoped offer, and record completed and failed transactions. Use incentives carefully because a discounted first order does not establish repeat willingness at the regular price. The page includes a decision table, a five-line first-transaction brief, a fictional repair-marketplace capacity example, and links to the DoorDash, Uber, and Airbnb cases.
