Metrics for a two sided marketplace product

Important note about this kind of product

  • In this kind of business, demand beats supply. You can always buy supply, but can’t buy demand
  • A marketplace without inventory ( listings- eBay, cars -Uber, rooms- Airbnb,…) is useless. In the early stage, it’s necessary to find an artificial way to populate both sides. I.e, Uber bought cars themselves to join taxi drivers, job searches page collected and posted recruitment posts manually.
  • Fraud and trust are crucial. Ratings, guarants are useful.
  • Keep the transaction within the network. Leakeage is problematic
