This document summarizes Retailigence, a company that provides a data platform for sharing real-time product inventory and location data between retailers and shopping apps. The platform allows retailers to attract new customers and drive foot traffic by making their inventory available to apps. It also gives app developers an API to access consolidated inventory data. Retailigence has received $1.5 million in seed funding and works with over 50,000 stores and 3 million products. Their case study on Nordstrom found that sharing inventory led to an 8% increase in same-store sales.
