Ramesh Johari, Stanford professor and advisor to marketplaces like oDesk (now Upwork), explains how these platforms succeed by removing transaction frictions—such as finding willing sellers or buyers—rather than directly selling goods or services. Both sides of the market are customers relying on the platform, and data science cycles through finding matches, making them, and learning via feedback to reduce those frictions over time.

Building Marketplaces Without Starting as One

Marketplaces rarely launch with scaled liquidity on both sides, so founders should first solve acute frictions unrelated to matching, like UrbanSitter enabling credit card payments for babysitters or oDesk providing work-tracking tools to build remote trust. Avoid premature marketplace commitments, such as fixed revenue cuts that invite disintermediation in long-term relationships (as oDesk faced pre-Upwork merger). Test scaled liquidity first—if only one side is strong, grow it or pivot to a firm-like model with controlled labor, as in Stitch Fix stylists or healthcare platforms needing curation.
