StockX COO Stephen Winn on how the marketplace verifies products, catches counterfeit sneakers and AirPods, and why CT scanning is the hardest check to fake.

Stephen Winn is Chief Operating Officer of StockX, the online marketplace where every single product sold passes through a verification process before reaching the buyer. He was employee number six, wrote much of the original platform code, and now oversees an operation spanning 170 countries, 5,000 trade lanes, and 71 million lifetime sales. We recorded this episode inside the company's Detroit verification center, where specialists scrutinize everything from shoes to electronics day in and day out.
Stephen walks Jon through the full defense-in-depth verification stack: machine learning risk scoring that runs before a package even arrives, RFID checks against chips embedded by brands like Nike and Adidas, trained verification experts who inspect stitching and packaging and even the smell of products, and a Lumafield CT scanner used on every product over $3,000. Since 2016 that process has stopped $750 million in products that failed to meet StockX's standards, including over $100 million in suspected counterfeit footwear. Winn explains why counterfeiters focus on what buyers can see and why internal structure remains the hardest thing to fake, recounts the CT scan that revealed Nike had hidden a numbered edition marking under the tongue of the Wizard of Oz Dunks, and closes with the go/no-go decision behind the patented all-in ask that keeps StockX a single global marketplace.
