Card infrastructure in Latin America has long been fragmented, expensive, and slow to innovate — a combination that has made it difficult for fintechs and financial institutions to launch card products without building significant infrastructure themselves. Pomelo was founded in Buenos Aires in 2021 to solve that problem with a card issuing platform designed specifically for the Latin American market. Its API-first infrastructure lets companies issue prepaid, debit, and credit cards without the complexity of building core processing capabilities in-house — a Banking-as-a-Service model applied to one of the regions with the greatest unmet demand for modern financial products. Pomelo has expanded across multiple Latin American markets and attracted backing from major investors including Tiger Global. Though founded and operating primarily in Latin America rather than Europe, it represents a model — embedded card infrastructure for the next generation of fintechs — that is directly relevant to the European market where similar platforms are competing for the same space. In an ecosystem where the ability to issue cards quickly and compliantly is a genuine competitive advantage, the companies providing that infrastructure sit in an increasingly valuable position.
