Yaysay is a feed-based, discovery-driven shopping app that launched in mid-December out of beta mode. Helmed by executives previously at Casper, Gilt Groupe and Stitch Fix, Yaysay is said to use AI technology that delivers a personalized, “relevant-for-you” feed of fashion items daily. The AI curates a short list of items for each user designed to provide “a 5-minute dopamine fix,” according to Wilmington, Delaware-based Yaysay, which is owned by Treasure Hunt Labs, Greenwich, Connecticut.
