We use Airbnb’s early test to show how a marketplace can begin with one urgent, bounded event instead of a broad launch. Three renters paid $80 each for air-mattress lodging during a San Francisco design conference; later, the 2008 Democratic National Convention supplied another deadline. We also describe the $40 cereal boxes that reportedly raised roughly $30,000 and the Craigslist listing integration. The practical checklist is to find an urgent event, complete the first transaction manually, follow early users’ next requests, and distribute where buyers already look.
