Juan Fantoni

Juan Fantoni has consolidated his profile within the Argentine fintech ecosystem through a career that combines technical training, international corporate experience and entrepreneurial development. As co-founder and CCO of Pomelo, he participates in the development of financial infrastructure for Latin America, with a focus on the issuance, processing and management of payment products. His previous experience at Mastercard allowed him to work closely with high-scale fintech companies and understand how technology, regulation, commercial partnerships and new financial service models are connected.
From engineering to the digital financial business
Juan Fantoni built a professional foundation based on technical training and business management. He studied Industrial Engineering at the Pontifical Catholic University of Argentina and later completed an MBA at Kellogg School of Management. This combination is central to understanding his profile: engineering gave him method, process analysis and a structural reading of problems, while executive training broadened his perspective toward strategy, commercial growth, team leadership and company expansion in competitive markets.
A career marked by specialization in payments
Before founding Pomelo, Fantoni held the position of Director of Fintech at Mastercard. From that role, he participated in issuing agreements with companies such as Mercado Pago, Ualá and Despegar, three relevant players in the transformation of digital payments in Argentina and the region. That experience brought him closer to the inner workings of the modern financial system, where card networks, issuers, processors, digital wallets, regulation, fraud prevention and user experience all interact.
Mastercard as an executive learning platform
His time at Mastercard functioned as a regional-scale training ground. In the payments business, each operation depends on a network of technical and commercial decisions that must be executed in seconds: authorization, validation, security, traceability and settlement. Fantoni developed there a precise understanding of the relationship between infrastructure and business. That perspective would become key to his entrepreneurial stage, because it allowed him to identify concrete needs among banks, fintechs and companies seeking to launch financial products more quickly.
Pomelo and the construction of fintech infrastructure
In 2021, Juan Fantoni founded Pomelo together with Gastón Irigoyen and Hernán Corral. The company was created with a specific proposal: to develop technological infrastructure so that banks, fintechs, crypto companies and businesses from other sectors can issue cards and offer financial services in Latin America. Pomelo works on a layer that is barely visible to the end user, but decisive for the functioning of the ecosystem: the technology that makes it possible to process operations, manage cards, integrate systems and scale financial products.
What it means to lead an infrastructure company
Pomelo does not operate as a financial application aimed only at consumers, but as a platform for other companies to build solutions on top of its technology. In this type of business, APIs play a central role: they are interfaces that connect systems in an organized and secure way. Through them, a company can issue cards, manage limits, process transactions or incorporate control tools without developing the entire architecture from scratch. This model requires technical precision, operational reliability and commercial insight.
Fantoni’s role as CCO
As CCO of Pomelo, Fantoni has a responsibility directly linked to commercial growth, client expansion and the construction of strategic partnerships. In a financial infrastructure company, selling does not only mean presenting a product: it involves understanding the client’s operational problem, translating technical capabilities into business value and supporting implementation processes that may involve legal, technological, commercial and regulatory areas. His leadership is located at that point of contact between product, market and scale.
A regional vision for Latin America
Pomelo’s expansion responds to a clear reading of the Latin American market. The region combines high digital adoption, fragmented financial systems, different regulations in each country and strong demand for new payment products. To grow in that context, a fintech infrastructure company needs to adapt to each market without losing technological consistency. Fantoni’s business vision is related to that capacity: building solutions that can be repeated, integrated and scaled, but with enough flexibility to operate in diverse financial environments.
Entrepreneurial leadership with corporate experience
The case of Juan Fantoni shows a relevant transition within the Argentine business ecosystem: moving from an executive position in a global company to the creation of a technology startup with regional ambition. That path requires a change in the type of leadership. In a corporation, scale already exists and the challenge usually lies in coordinating resources; in a startup, scale must be built. Fantoni brought to the project a combination of industry knowledge, relationship networks, commercial judgment and experience in payments.
Recognition within the fintech ecosystem
Pomelo gained visibility in the entrepreneurial ecosystem for its growth, its ability to attract investment and its positioning as infrastructure for financial services. Fantoni has also been recognized in spaces linked to the Argentine startup world, where his name appears associated with the development of a new generation of technology companies. Rather than as a traditional public figure, his influence is understood through the construction of a company that works on the technical foundation that allows other players to launch competitive financial products.
Technology, regulation and operational trust
Leadership in fintech does not depend only on visible innovation. A digital card, an account or a payment system requires security, regulatory compliance, technological availability and processing capacity. Fantoni operates in that area where trust is part of the product. If the infrastructure fails, the financial service loses value. For that reason, his profile combines commercial vision with an understanding of the operational architecture that supports each transaction, an especially important competence in high-volume businesses with low tolerance for error.
An Argentine profile with regional projection
Juan Fantoni represents a type of business leadership linked to the new financial infrastructure of Latin America. His career brings together academic training, experience in a multinational payments company and entrepreneurial development from Argentina. As co-founder and CCO of Pomelo, his contribution focuses on turning knowledge of the financial system into a platform capable of enabling new products for banks, fintechs and companies. His influence is measured in the ability to build technology that other businesses use to grow.
