Nordstrom uses an in-house platform called the Nordstrom Analytical Platform (NAP) that runs over 100 AI models daily to support real-time decisions spanning inventory routing, fulfillment, personalized product discovery, and customer service insights.

Described publicly by Nordstrom's then-CTO Edmond Mesrobian, NAP is a real-time, event-streaming analytical platform that ingests signals from stores, fulfillment centers, and online channels. The platform translates business events through layered AI models to generate predictions used for tasks such as routing orders to nearby stores, inventory control, personalized product recommendations, and customer credit insights. A 'fashion map' component uses deep learning and natural language processing to interpret images and social data to understand customer style preferences.
