As digital banking continues to reshape financial services across Latin America, one company has emerged as a major force by combining rapid customer growth with a technology-driven approach to banking. What began as a fintech challenger in Brazil has evolved into one of the world’s largest digital financial platforms, serving millions of customers across multiple countries.
A significant step in that growth story came in July, when the company’s Mexican subsidiary received authorization from the National Banking and Securities Commission (CNBV) to begin operating as a bank. The approval followed a review process involving the CNBV, the Bank of Mexico, and the Ministry of Finance and Public Credit. With more than 15 million customers already using its services, the company is positioned to become the largest digital bank in Mexico.

The achievement marks another milestone in an expansion strategy that began with the company’s entry into Mexico in 2019. Since then, it has rapidly built a nationwide presence, reaching approximately 15% of the country’s adult population. The platform now adds an estimated 12,000 customers daily and has established a footprint in nearly every municipality across the country.
Mexico has become one of the company’s most important growth markets. During the first quarter of 2026, the operation reached breakeven, while customer deposits surpassed US$5.9 billion. Improved operating efficiency and growing customer engagement have helped demonstrate the viability of its digital-first banking model in a highly competitive market.
The company’s Mexican business launched with a no-fee credit card in 2020, offering flexible payment options tailored to local consumer needs. Since then, its product lineup has expanded considerably. Customers now have access to savings accounts, personal loans, secured credit cards, and a range of digital tools designed to help manage money more effectively.
Recent additions include savings features aimed at encouraging wealth accumulation as well as security tools intended to help customers identify potential fraud attempts. The broader strategy centers on attracting consumers who may have limited access to traditional banking products while providing a more streamlined digital experience.
The impact of that approach can be seen in customer adoption data. More than half of the company’s Mexican customers received their first credit card through the platform, while a majority of users report developing stronger savings habits after joining. These figures highlight the growing role digital banks are playing in expanding access to financial services.
While international operations continue to grow, Brazil remains the company’s largest market and foundation for future expansion. Recent research conducted by Bain & Company’s NPS Prism found that the institution ranked as the primary financial provider for millions of Brazilians during the fourth quarter of 2025. In 17 states, roughly 30% of residents identified it as their main banking relationship.
The strongest adoption rates were recorded in Brazil’s North and Northeast regions, where primary institution incidence reached 34% and 31%, respectively. Even in areas with lower levels of penetration, the company’s presence remained significant, reflecting its broad reach across the country.
Those findings were included in the latest edition of Data Nubank, a recurring study that examines the company’s economic and social impact throughout Brazil. The report highlights trends in financial inclusion, banking access, savings, and credit distribution across the country’s regions.
One area where the company has had a particularly notable influence is in municipalities lacking traditional banking infrastructure. Nearly half of Brazilian cities have no physical bank branch, creating what are often referred to as banking deserts. In several states, more than 80% of municipalities fall into this category.
As mobile technology becomes increasingly important for accessing financial services, digital banking platforms have helped bridge some of those gaps. Data from the report indicates that regions with fewer conventional banking options often show stronger adoption of digital financial services, suggesting that customers are turning to online alternatives when physical branches are unavailable.
According to the study, the institution has helped bring approximately 31.5 million Brazilians into the formal banking system. In more than 15 states, its customers account for more than one-fifth of the adult population.
The company’s economic footprint is also growing. In lower-income regions where access to traditional banking has historically been limited, customer adoption rates have generally been higher. The data suggests that digital banking is playing an increasing role in connecting underserved populations to financial products, savings tools, and credit.
Credit activity has become a particularly important part of that story. In Brazil’s Northeast region, the company’s credit portfolio represented 6.8% of regional GDP during 2025, exceeding 8% in at least one state. The figures illustrate how digital lenders are becoming more deeply integrated into local economies.
Meanwhile, the company estimates that its customers collectively saved roughly R$134.7 billion in fees and annual banking charges through 2025. Those savings remained in consumers’ pockets rather than being spent on banking costs, providing additional financial flexibility for households.
Why This Matters for Investors
The company’s growth trajectory reflects the continued expansion of digital finance throughout Latin America. Its progress in Mexico demonstrates an ability to replicate its model outside its home market, while its strong position in Brazil provides a foundation for further growth.
As banking increasingly shifts toward mobile-first platforms, the company stands as one of the clearest examples of how technology is reshaping financial services across the region. The next phase of its story will likely be defined not only by customer growth, but also by its ability to translate scale into long-term profitability.
