Rexi, a startup founded by Argentine entrepreneurs, recently raised US$1.2 million in a pre-seed funding round that included investors such as Underscore, Flybridge, Pear, NFX, Textbook, and Carao Ventures.
The company has created an AI-first operational infrastructure platform designed for businesses operating at scale and will use this capital to drive the development of its business model. It also plans to expand its team and strengthen its commercial presence in global markets, such as the U.S.
The startup, which currently works with companies that move money—including banks, neobanks, and payment processors—has a platform designed to automate reconciliations and strengthen control over financial flows for its client portfolio.
Founded in 2025, with a commercial base in New York and development in Buenos Aires, Rexi places a strong emphasis on its AI-first architecture, which is not limited to detecting inconsistencies but is designed to resolve them, absorb operational complexity, and continuously learn the rules, exceptions, and patterns specific to each organization.
“This capital propels us toward achieving our goal of helping clients transform the way they operate with AI, viewing Rexi as their critical partner in doing so,” said Ignacio Berardi, co-founder and CEO of Rexi, in an interview with Contxto.
Among its many strengths, the startup uses a collaborative platform that connects internal teams (finance, operations, product) as well as external partners in a commitment to not only process transactions but also resolve discrepancies through more comprehensive services.
The team consists of CEO Ignacio Berardi, Teo Zavalia, who has experience at Mercado Pago and FJ Labs, and Sebastián García, who has worked at Mercado Libre, Naranja X, and Pomelo. Together, these entrepreneurs created Rexi, which is currently establishing itself in the industry with a value proposition that reduces the operational burden of reconciling transactions in organizations that constantly move money.
Unlike similar services, the company operates directly on raw data, reducing complex integrations, extensive implementations, and reliance on professional services. According to Berardi, they integrate an agent-based experience—a dynamic reconciliation logic that adapts to constant changes in data, operations, and business requirements.
Its architecture is designed not only to identify problems but also to solve them through intelligent automation, allowing teams to focus on innovation, customer experience, and growth.
In addition to expanding into the United States, Rexi is working hard to forge partnerships to accelerate adoption and expansion into other verticals beyond banking, payments, and insurance (e.g., marketplaces and retail), as well as continuing to invest in talent to build a strong team in the region.
