A real-world example

For each customer, which items from the new collection will they purchase in the next 30 days?

New products have zero interaction history — collaborative filtering fails completely. Fashion retailers launch 200-500 new items per season and have no data on who will buy them. Traditional approaches default to showing new items to everyone or using simple attribute matching. First-week sell-through on new collections averages 8-12% when it should be 25-35%. For a fashion retailer doing $2B annually, improving new-collection sell-through by 10 points is worth $40-60M per season.

How KumoRFM solves this

Relational intelligence for true personalization

Kumo solves the cold-start problem by using the relational graph — similar products, same brand, category affinity, style attributes, and cross-customer purchase patterns — to recommend items with zero interaction data. The model learns that customers who bought last season's linen collection from the same brand, in similar colorways, at similar price points, are the best targets for the new Spring 2025 line. No interaction history required.
