Mastercard: Generative AI Merchant Enrichment (GAIME)

We are the first team at Mastercard to build an AI-powered, API-based product on Databricks—GAIME. GAIME is a fuzzy-matching algorithm, which matches transaction/merchant descriptors with Mastercard's real-time merchant database. GAIME consists of entity recognition, candidates retrieval via embeddings + vector search and uses AI-as-a-judge to produce a final match decision.

The talk is organized around three foundational pillars of an AI-powered product: governance, responsible AI and quality control. We will discuss how these pillars become accelerators rather than constraints at the regulated financial sector. Finally, we will share the journey of moving GAIME from POC to production and demonstrate what role data science plays in scaling high-impact AI products within a regulated environment.
