Marketplace and platform economics follow a unique pattern: the "chicken and egg" problem. You need supply to attract demand, and demand to attract supply. The solution: subsidize one side initially to bootstrap the network.
Key marketplace concepts: (1) Network effects — each user adds value for all users, (2) Take rate — your commission on each transaction, (3) GMV — total transaction volume, (4) Liquidity — % of listings that get transacted.
Key Takeaways
- Marketplaces have chicken-and-egg problems — subsidize one side first.
- Revenue = GMV × Take Rate. Both must grow.
- Network effects create exponential value as the platform scales.
- Liquidity (conversion rate) is the most important early metric.
