A single financial API for seamless, borderless banking across the Americas.
Shot for the record: a flame on a dark field. The name comes from Prometheus, the titan who handed fire to mortals - which is, more or less, what a banking API does for a developer who would otherwise be integrating with 283 banks one at a time.
Latin America is not one banking market. It is roughly twenty of them, each with its own institutions, protocols, quirks, and a general reluctance to talk to anyone. Prometeo looked at that mess and made a decision that sounds either brave or slightly unhinged: treat the whole thing as a single market, behind a single API.
Here is the thing about financial infrastructure. It is enormously valuable and almost completely invisible. When you send money and it arrives, you don't think about the dozen systems that had to agree on what just happened. You only notice infrastructure when it fails. Prometeo lives in that unglamorous space - the part of fintech that isn't an app with a nice gradient, but the plumbing underneath it that makes the app possible.
Founded in 2018 in Montevideo by Ximena Aleman, Rodrigo Tumaian, and Eduardo Veiga, Prometeo does three deceptively simple things through one integration: it confirms a bank account is real, it pulls financial data (with the account holder's permission), and it moves money. Do those three things reliably across the Americas and you have built something a lot of companies would rather buy than build. Which is the entire business.
Prometeo's product line reads like a list of the problems that quietly ruin a fintech's day. Failed payouts. Fraud. Bank integrations that take six months. Each product is a fix for one of them.
Initiate account-to-account payments, transfer to third parties, run mass payout dispersals, and accept payins from customers - across Latin American banks.
A real-time check that a bank account is valid and reachable before you send money. Fewer failed payouts, less fraud, fewer awkward customer emails.
Collect and centralize account and client financial data - always with the end user's authorization. The backbone for lending, underwriting, and treasury.
US bank account ownership verification that matches the account holder's name, cutting misdirected payments and fraud.
An API layer built for a world where software agents - not just humans - need to read banking data and move money programmatically.
The three co-founders had built businesses together before Prometeo. That matters more than most cap tables admit - a team that has already survived the hard conversations tends to move faster through the next ones.

In January 2024, Prometeo closed a $13M Series A led by Antler Elevate. The interesting part isn't the number - it's who showed up. When PayPal and Samsung both write checks into your open-banking company, they are telling you something about where they think Latin American payments are going.
| Round | Amount | Date | Lead / Notable Investors |
|---|---|---|---|
| Series A | $13M | Jan 2024 | Antler Elevate (lead), PayPal Ventures, Samsung Next, DN Capital, Cometa, Magma Partners |
| Seed / Early | ~$6M | 2018-2021 | Magma Partners, Cometa |
Reported valuation after the round: just under $100M (per TechCrunch). Revenue reportedly grew roughly 10x over two years - the kind of curve you get when your moat is integrations rather than ad spend.
