Sanctuary Sneakers is a local early-stage startup that aggregates and leverages all available sneaker data in one place to compare prices and reveal the best deals. Their web app digs up real-time prices, inventory, and more information for both new & used sneakers from the most popular online marketplaces and stores so you don't have to! It is a perfect example of data integration from different disparate data sources. Check them out at https://sanctuarysneakers.com
