Headstart designed a two-model pipeline separating image understanding from query matching. GPT-4o Vision API processes incoming product images, extracting structured attributes including materials, silhouette, and luxury-specific style markers. Claude then interprets the sourcing query and applies matching logic, returning ranked product recommendations. The matching system was trained on Sourced By's historical sourcing data, creating a proprietary dataset the business now owns. The full pipeline was delivered from kickoff to working MVP in five weeks.
