Mexico City: the emerging Latam tech hub

CDMX has quietly become one of the most important technology hubs in Latin America. A large domestic market, proximity to the US, and a growing pool of engineering talent have produced a deep fintech and e-commerce scene. Kavak led the way in used-car marketplaces, Clip rebuilt SMB payments, Bitso anchors crypto in the region, Konfío serves SME lending, and Stori is reinventing consumer credit. Mercado Libre, Rappi and Didi run large engineering teams out of Polanco, Roma and Condesa, and Silicon Valley funds treat the city as their primary Latam base.

Teams here move fast and think in US dollars and US customers as naturally as in pesos. AI budgets are tight, so cost-aware engineering actually matters.
