Andrew Chen ran rider growth at Uber and now invests at a16z, so this is the canonical breakdown of how marketplaces get off zero. He organizes the best thinking on the chicken and egg problem around one honest idea: you almost never launch supply and demand at once, you seed the harder side first (usually supply) in a tiny atomic network, then pull the easy side in. Treat it as a starting map of tactics, then pick the one or two that fit your city and niche.
- Solve the chicken and egg problem by picking the hard side (usually supply) and getting it dense in one narrow slice: a single city, campus, or vertical, before going wide.
- Liquidity, not signups, is the real metric: enough activity that a buyer who shows up actually finds a match.
- You can bootstrap one side manually (curate listings, run single-player-mode value) before the other side exists, which answers the 'no supply or demand yet' worry directly.
