About Prometeo
Prometeo is a borderless fintech infrastructure company that connects global corporations to more than 7,500 financial institutions across 50+ countries through a single API. Where others see a patchwork of incompatible payment rails, fragmented data standards, and bank-by-bank complexity, Prometeo sees a solvable infrastructure problem and has spent the last several years building the layer that solves it.
The company was founded in Uruguay by Ximena Aleman and Rodrigo Tumaián, who identified a persistent structural gap across Latin American financial markets: banks were not interoperable, integrations were custom and slow, and scaling across countries meant rebuilding from scratch in every new market. Rather than work around that fragmentation, Prometeo set out to absorb it entirely, building a translation and enrichment layer that standardizes what comes back from banks and enriches what goes in, so that transactions can actually complete, not just connect.
That core insight has since proven universal. The same fragmentation that defined Latin America also characterizes financial infrastructure in the United States and across global markets. Prometeo now operates across 50+ countries, including the US, and counts JP Morgan, Citi, SWIFT, MercadoLibre, Bancolombia, Santander, and BBVA among its partners and clients.
Through one integration, businesses using Prometeo can validate bank accounts and identity data, move money via account-to-account payments, manage treasury visibility across jurisdictions, and orchestrate cross-border financial workflows without managing multiple local providers or rebuilding infrastructure market by market.
The business has scaled steadily since its Series A in January 2024, a $13M round led by Antler Elevate, with participation from PayPal Ventures, Samsung Next, DN Capital, Cometa, and Magma Partners. Since that raise, Prometeo has delivered a 150% increase in customer growth, a 7x increase in cross-border account validations in 2024, and the launch of its Borderless Banking suite and Agentic Banking product, the first AI-driven financial infrastructure layer in the region, enabling intelligent agents to autonomously perform financial operations within a secure, auditable, and compliant architecture.
Prometeo also tracks the real cost of the problem it solves. Based on millions of verifications processed across the Americas in 2025, its data show that 19% of corporate transactions fail before being sent: 12% due to incorrectly entered data and 7% to non-existent or inactive accounts. In Brazil, total operational risk from failed payments reaches 50%. These are not edge cases. They are infrastructure failures with direct capital consequences, and Prometeo is the layer that prevents them.
Co-founder and Co-CEO Ximena Aleman was recognized as a World Economic Forum Technology Pioneer in 2025 and named among the Top 100 Women in FinTech. Co-founder and Co-CEO Rodrigo Tumaián brings deep expertise in cybersecurity and financial compliance, and currently serves as President of the Uruguayan Fintech Chamber.
Prometeo’s vision is straightforward: a company in Mexico should be able to validate a US account, send a payment in Brazil, and manage treasury across markets in real time, through a single integration, without it feeling exceptional. That infrastructure already exists. Prometeo built it.
