Why did Kozmo.com fail, and when did on-demand delivery become viable?

Formed since 2026-10-25 · ledger #47

Smartphone GPS dispatch and gig couriers arrived around 2011-2013; the winners were founded inside that window.

Short answer

Kozmo.com promised one-hour delivery of almost anything in 1998, raised about $250M and shut down in April 2001. DoorDash (2013) and Postmates (2011) ran the same idea with GPS dispatch to contractors paid per delivery, on phones. The binding constraint was the cost of dispatching couriers, and it crossed with smartphones.

Kozmo employed couriers and ran warehouses; per-delivery contractors routed by phone turned a fixed cost into a variable one.
