19 Tactics to Solve the Chicken-or-Egg Problem and Grow Your Marketplace

James Currier · NFX Free Intermediate

For a two-sided marketplace, the first real decision is which side to define and win first, and this essay makes the case plainly: figure out which side is harder to get, because that side is usually the more valuable one, and once you have it the other side gets 2 to 10 times easier. It then walks through concrete ways to seed that harder side without the other side existing yet, so it is a starting point for the pick-two problem rather than abstract theory. NFX has studied more marketplace network-effect businesses than almost anyone, which is why this is the canonical reference founders keep returning to.

  • Identify the constrained (harder to acquire) side first, and define your ideal customer there, because that side sets the pace for the whole marketplace.
  • You can build standalone value for one side before the other exists (for example a tool suppliers use whether or not buyers are present) so you are not stuck waiting for both.
  • There are many concrete seeding levers (subsidies, geographic or category constraints, manual matching), so pick the two or three that fit your niche instead of trying all of them.
