Marketplace

Marketplaces take a small cut of every deal made between other people on their site. The system grows more valuable as more people join, creating a network that works without needing anyone’s permission. The secret sauce is the trust and easy connection they provide that others can’t easily copy. This model creates wealth by owning the “town square” instead of the goods. Airbnb and Etsy prove you can run a global business without owning any inventory.
