Take Rate Drivers: Frequency, Ticket, Labor

In this episode of Run the Numbers, CJ breaks down the 5,000-year history of marketplaces—from Mesopotamia to Amazon—and the economics behind take rates, trust layers, and vertical unbundling. We unpack Airbnb’s fee backlash, Facebook Marketplace’s hidden value, why inventory kills platforms, and how AI will reshape discovery—without eliminating the middleman.
