Prex
Overview
Prex is a multi-country LATAM fintech offering free digital accounts linked to international Mastercard prepaid cards, managed through a mobile app [1, 3, [ar-cro]]. Founded 2015 in Uruguay, Prex launched in Argentina (2019) and Peru (2021) — expanding across the Southern Cone. By November 2023, Prex had 2.2 million users across its three countries; subsequent growth has brought regional total to 3+ million users. The structural distinction: Prex is one of the few LATAM fintechs operating across multiple national markets simultaneously — Uruguay + Argentina + Peru — rather than focusing on a single home country.
The platform's value proposition: Mastercard-prepaid-card-linked digital account + mobile app + free — providing international payment-network reach without requiring traditional bank accounts. Recent partnership: Prex + Allaria launched a high-yield savings account in Argentina — expanding from pure prepaid-card into yield-bearing financial product. The structural significance: Prex demonstrates Uruguayan fintech regional expansion — small-economy origin (Uruguay) scaling to larger Southern Cone neighbours (Argentina + Peru). Within Argentina, Prex competes with Mercado Pago, Ualá, Naranja X, MODO, plus local bank wallets — illustrating Argentine fintech's intense competition.
