Cold Start Problem

TL;DR

The chicken-and-egg challenge of bootstrapping a marketplace or network where each side requires the other to be useful.

The cold-start problem is the early phase where a network has too few participants to be valuable to any of them. Andrew Chen's 'Cold Start Problem' enumerates standard solutions: pick a small atomic network (a city, a campus, a vertical), seed one side first (often supply), use single-player utility to attract one side without the other, and use 'tipping' moments to break out of the niche.

Getting through cold start typically requires unscalable founder work — manual recruiting, hand-curated supply, or even running the supply side as the company itself in the early days.

Worked example

OpenTable solved its cold-start by giving restaurants the reservation-management software for free, even before there were any diners — once 1,000 NYC restaurants used it, OpenTable could finally launch a consumer app with real inventory and real bookings.

Common pitfalls

• Trying to launch globally instead of in a single atomic network.
• Optimizing both sides equally instead of seeding the harder side first.
• Giving up on cold start before reaching local liquidity.
