About
José Murillo is a co-founder and co-CEO of Primero, the Mexico City company building AI infrastructure for Latin America's largest enterprises, which raised a $12 million seed in August 2026 — among the largest seed rounds ever raised in Latin America — co-led by Kaszek and General Catalyst. He studied economics and computer science at Harvard and worked at Meta and Goldman Sachs in the United States before returning to Mexico, where he had earlier been CEO of Samsam, a General Catalyst- and Neo-backed startup. He founded Primero with Andrés Rosales and Santiago Buenahora on the argument that Latin America's biggest enterprises still run on 1990s technology and need a homegrown AI champion rather than an imported one — "LatAm needs its own technology champions," as he put it at launch — and the company now serves enterprises with more than $45 billion in combined annual revenue.
