Generic Recommendations Leaving Money on the Table

The client had $200M annual online revenue, 2.8M active customers, and 150,000 SKUs. Their existing rule-based engine had 0.8% CTR on recommendations. Pain points: generic 'customers who bought X also bought Y,' no contextual understanding, cold start problem, and inventory bias.

Challenge: Build an AI system that understands fashion, personal style, context, and intent to deliver truly personalized recommendations across all touchpoints.

Multi-Model AI Recommendation Ecosystem

We built a multi-model ensemble: Style Understanding AI (GPT-4 Vision + fashion models), Collaborative Filtering (matrix factorization + deep learning), Content-Based (product embeddings), and a GPT-4 Ranker for final ordering.
