Mateo Ríos

X.O. was born in 2020 from the creative vision of executive chefs Rob Pevitts, Mateo Ríos and Sebastián Marín, a collective dedicated to exploring Colombia’s biodiversity through research, innovation and deep collaboration with local producers. Their work highlights the complexity of the country’s food chain and directly supports the farmers, artisanal fishers and communities who shape Colombia’s culinary identity.

In 2023, just two years after opening, X.O. earned significant regional acclaim, ranking among Latin America’s top restaurants for the second consecutive year. These achievements strengthened Medellín’s rising status as a leading gastronomic destination. In 2025, Sebastián received a prestigious Knife Award from The Best Chef, recognising his growing influence on the international stage.

Born in Medellín, Mateo completed his culinary studies in Colombia and Argentina before joining the Carmen Family in 2010. Today, he co-leads the kitchen at X.O., working alongside Sebastián and Daniela. His passion for aquaculture and coastal products has driven the development of advanced ageing and cooking techniques with the Bio-Lab team, further defining X.O.’s innovative and ingredient-driven approach.
