How Marketplaces Use Counterparty Ratings to Build Trust

Episode 49 of Marketplace Businesses with Fexingo explores how two-sided platforms use counterparty ratings — not just product reviews — to solve the trust problem between buyers and sellers. Lucas and Luna examine the mechanics behind eBay's seller and buyer ratings, Uber's driver and passenger scores, and Upwork's dual feedback system. They discuss why symmetric rating systems matter for liquidity, how platforms prevent rating inflation and retaliation, and the trade-off between trust and friction. Specific data points include eBay's 1996 introduction of seller feedback, the 2014 'buyer beware' reform that allowed seller-specific reviews of buyers, and the finding that a half-star increase in driver rating yields 20% more ride requests. This episode explains why the best marketplaces rate both sides of the transaction. #MarketplaceBusinesses #TwoSidedNetworks #CounterpartyRatings #Trust #eBay #Uber #Upwork #Liquidity #TakeRates #Reviews #PlatformDesign #ReputationSystems #FeedbackLoops #Business #Technology #FexingoBusiness #BusinessPodcast #MarketplaceDesign Keep every episode free: buymeacoffee.com/fexingo
