How Marketplaces Are Building Their Own Fraud Detection Stacks

Episode 61 of The Platform Economy with Fexingo dives into a critical behind-the-scenes shift: marketplaces are abandoning third-party fraud detection services and building their own machine learning models. Lucas and Luna unpack why Stripe Radar, Sift, and Forter no longer suffice for platforms like Airbnb, Uber, and Etsy. The hosts walk through a specific case—how a mid-sized marketplace used transaction graph analysis to catch synthetic identity rings that traditional score-based systems missed. They also discuss the tension between fraud detection and friction, and why in-house models can reduce false positives by 40 percent while catching 15 percent more fraud. No ads, just a sharp, specific conversation for operators and builders. #FraudDetection #Marketplaces #PlatformEconomy #Airbnb #Uber #Etsy #MachineLearning #GraphAnalysis #SyntheticIdentity #StripeRadar #Sift #Forter #InHouseAI #Business #Technology #FexingoBusiness #BusinessPodcast #PlatformStrategy Keep every episode free: buymeacoffee.com/fexingo
