For retailers, shelf. does two big things ... #1 - shelf brings you additional customers in your area at no cost to you. By showcasing your live inventory data you can attract real nearby shoppers who may have otherwise bought online or at a big box retailer. #2 shelf. provides retailers with high end analytics that are otherwise unavailable or too expensive. Due to the nature of the app, shelf. is able to provide retailers with accurate consumer data tailored to each store's location, giving visibility into nearby consumer demand that could otherwise be lost to a competitor or online retailer.
