Reimagining the world through Data & AI.

Hi, I’m Oscar Marin — a Managing Director at EY focused on Data and AI. I help large enterprises turn fragmented data into shared knowledge so their AI systems can actually reason, act, and scale.

My work centers on the layer most organizations skip: meaning. Ontologies, semantic models, and knowledge graphs are what give agentic AI the context it needs to operate reliably across complex business environments. In a world where models and compute are becoming commodities, knowledge is the moat.

Outside of work, I’m a husband and father of two, a lifelong learner, and I build open-source tools and side projects exploring the intersection of AI and everyday life.
