Background

About

25+ years building and scaling technology companies with Digital and AI.

I served as CTO and co-founder of three companies in Latin America: Apontador (15M+ monthly users), Maplink (3B+ API requests), and TruckPad, with successful scale, fundraising, and exits.

Today, as Partner and Technology Leader at McKinsey in Latin America, I work with CEOs and CTOs at leading banks, retailers, and technology companies to launch AI products and cloud-native platforms.

My focus is to build AI-native companies that combine people and intelligent agents to generate results in quarters, not years.
