Key Fintech Companies in South America

South America stands out as one of the world’s fastest-growing fintech regions, rivaling markets in Asia and Europe for both investment and innovation. Over the past decade, the continent has transformed its financial landscape through necessity, resilience, and creativity. For decades, millions of South Americans lived outside the formal financial system, relying heavily on cash transactions, informal loans, or remittance networks that charged high fees. Banks were often viewed as institutions serving only the wealthy or large corporations, leaving small businesses and ordinary citizens excluded.

Into this gap stepped fintech entrepreneurs who identified opportunities to reimagine finance through mobile apps, digital wallets, peer-to-peer lending, and blockchain-based solutions. Their mission has not only been to drive profits but also to solve deep-rooted economic challenges such as financial exclusion, hyperinflation, and distrust in institutions. By doing so, they have reshaped expectations around accessibility, convenience, and transparency.

For readers of FinanceTechX, understanding South America’s fintech trajectory is essential to grasping the global evolution of digital finance. While North America and Europe remain influential, the future is increasingly being written in emerging markets like Brazil, Argentina, Colombia, and Chile. These countries, once considered financially fragile, now foster some of the world’s most valuable and impactful fintech companies.

Brazil: The Regional Fintech Leader

Brazil commands the spotlight in South America’s fintech revolution, representing over 40% of all fintech activity in Latin America. A nation of over 200 million people, Brazil combines widespread smartphone usage with historically high banking costs and fees. This environment created a perfect storm for fintech disruption, producing global leaders that have become case studies for investors worldwide.

Nubank: Redefining Digital Banking

Nubank is arguably South America’s most influential fintech company and one of the world’s largest digital banks. Founded in São Paulo in 2013 by David Vélez, Cristina Junqueira, and Edward Wible, Nubank began with a mission to simplify access to credit. Its no-fee purple credit card quickly gained popularity among Brazil’s young and tech-savvy population, who were frustrated with legacy banks charging excessive fees for basic services.

Over the years, Nubank expanded into savings accounts, personal loans, insurance, and investment products. By 2025, it serves more than 90 million customers across Brazil, Mexico, and Colombia. Nubank has also ventured into small business services, offering digital accounts tailored for entrepreneurs and merchants. The company went public on the New York Stock Exchange in 2021, achieving one of the largest IPOs ever by a Latin American company.

Nubank’s success is rooted in its obsession with user experience. Its mobile app, designed with simplicity and transparency in mind, contrasts sharply with the bureaucratic processes of traditional banks. In addition, Nubank has cultivated a reputation for customer service excellence, resolving complaints efficiently and using customer feedback to continuously improve its offerings.

From a financial inclusion perspective, Nubank has been transformative. Millions of previously unbanked Brazilians now access credit, savings, and financial tools through the platform. Its expansion into Mexico and Colombia illustrates its ambition to become a pan-regional powerhouse.

StoneCo: Empowering Small Merchants

StoneCo, another Brazilian fintech giant, focuses primarily on empowering merchants. Founded in 2012, StoneCo provides payment processing, financial services, and point-of-sale solutions to small and medium-sized enterprises (SMEs). Backed by Berkshire Hathaway, StoneCo gained international recognition for its scalable business model.

In Brazil, SMEs often struggle to access affordable financial tools, leaving them dependent on cash transactions. StoneCo’s offerings allow businesses to accept card payments, manage cash flow, and access working capital loans. By 2025, it has become a lifeline for merchants navigating Brazil’s highly competitive retail landscape.

What distinguishes StoneCo is its commitment to building personal relationships with merchants, often through field representatives who support onboarding and problem-solving. This blend of technology and human interaction has built trust and loyalty in a country where small businesses are the backbone of the economy.

PagSeguro: Expanding Financial Access

PagSeguro, launched as part of UOL (Universo Online) in 2006, is another transformative player in Brazil’s fintech landscape. Initially a payments processor, PagSeguro expanded into digital wallets, credit, and financial services. Its biggest impact has been in enabling micro-entrepreneurs and informal vendors to join the digital economy.

With low-cost mobile card readers and user-friendly apps, PagSeguro helped millions of small businesses accept electronic payments. Over time, it evolved into a fintech ecosystem with services ranging from consumer credit to investment products. By 2025, it competes directly with Nubank and StoneCo, contributing to Brazil’s shift toward a cashless economy.

XP Inc.: Democratizing Investments

While Nubank, StoneCo, and PagSeguro focus heavily on banking and payments, XP Inc. has carved out a niche in investments. Founded in 2001 and later transformed into a digital investment platform, XP gives ordinary Brazilians access to stocks, bonds, mutual funds, and alternative investment products.

Historically, investing in Brazil was limited to wealthy elites, but XP has democratized access, encouraging a new generation of retail investors. By offering digital platforms combined with education and advisory services, XP has become a symbol of financial empowerment. Its growth demonstrates how fintech is not only solving inclusion in banking but also in wealth management and capital markets.

Argentina: Innovation in an Unstable Economy

If Brazil represents scale and stability, Argentina represents resilience and creativity amid economic turmoil. For decades, Argentina has battled hyperinflation, debt defaults, and volatile exchange rates. These challenges might deter traditional banks, but fintech startups have thrived by offering practical solutions tailored to an uncertain economy.

Mercado Pago: Latin America’s Super App

Mercado Pago, the fintech arm of Mercado Libre, is one of the most dominant digital financial platforms in the region. Integrated into Mercado Libre’s e-commerce ecosystem, Mercado Pago offers digital wallets, QR code payments, credit, and investment options.

Its success underscores the power of ecosystem integration. By leveraging Mercado Libre’s e-commerce dominance, Mercado Pago has embedded itself in daily financial interactions for millions of users.

Ualá: Banking for the Unbanked

Another Argentine success story is Ualá, founded in 2017 by Pierpaolo Barbieri. Ualá provides prepaid debit cards linked to a mobile app, offering users tools for payments, transfers, savings, and loans. Its appeal lies in simplicity and accessibility, especially in a country where traditional banks often impose barriers for low-income users.

By 2025, Ualá has issued millions of cards and expanded operations into Mexico and Colombia. Partnerships with international institutions like Goldman Sachs and Mastercard have provided it with stability and credibility despite Argentina’s turbulent macroeconomic environment.

Ualá’s strategy demonstrates the importance of customer empowerment. By targeting youth and previously unbanked populations, it has captured a loyal customer base while positioning itself as a regional leader in financial inclusion.

Belo and Crypto-Driven Solutions

Argentina’s economic volatility has made it a global hub for cryptocurrency adoption, and fintechs like Belo have capitalized on this trend. Belo offers users the ability to save and transact in stablecoins, protecting their wealth from peso devaluation. By providing seamless fiat-to-crypto conversion, it has gained popularity among Argentines seeking stability.

Argentina’s fintech ecosystem thus illustrates how necessity drives innovation. Whether through Mercado Pago’s scale, Ualá’s inclusion, or Belo’s crypto resilience, Argentine fintechs are creating models that resonate far beyond national borders.

Movii: Serving the Excluded

Movii stands as a pioneer of digital wallets in Colombia. Founded in 2018, it offers prepaid debit cards, mobile wallets, and remittance services. Movii’s mission is straightforward: to bring financial access to people excluded from traditional banking.

With zero maintenance fees and simplified onboarding, Movii became a trusted platform for millions of Colombians. Its focus on remittances is especially critical in a country where migrant workers rely heavily on cross-border payments. By 2025, Movii also integrates cryptocurrency features, allowing users to transact with stablecoins and protect their savings from inflation.

Movii’s expansion highlights fintech’s social impact dimension. Beyond profits, it has given millions the tools to participate in Colombia’s formal financial system.

Chile: A Stable Hub for Fintech Innovation

Chile’s fintech sector benefits from macroeconomic stability, strong institutions, and one of the region’s highest GDP per capita rates. Its financial system is sophisticated, but traditional banks often cater to upper-income segments. Fintech startups have filled the gap by offering accessible and transparent alternatives. By 2025, Chile counts more than 250 fintech companies, with wealth management and payments being the strongest categories.

Fintual: Democratizing Investments

Fintual is one of Chile’s flagship fintech companies. Launched in 2016, it is the first Chilean startup to be approved by both the Chilean and Mexican securities regulators.

Peru: Mobile Wallet Dominance

Peru’s fintech market is smaller than Brazil or Argentina, but it is growing at one of the fastest rates in the region. The country has historically had high levels of cash dependency, with nearly 70% of transactions in 2019 still occurring in cash. Fintech companies have targeted this challenge head-on with mobile wallet solutions that simplify payments and transfers.

Yape: The People’s Wallet

Yape, developed by Banco de Crédito del Perú (BCP), is Peru’s most popular mobile wallet. It allows users to transfer money instantly using just a phone number, bypassing the need for a bank account. By 2025, Yape boasts over 12 million users, making it one of the most widely adopted fintech platforms in the country.

Yape’s impact is profound: street vendors, taxi drivers, and small businesses now accept digital payments, reducing reliance on cash. The app’s integration with e-commerce and bill payment further embeds it into everyday life.

Plin: A Strong Rival

Plin, backed by several major Peruvian banks including BBVA, Interbank, and Scotiabank, has emerged as Yape’s primary competitor. Plin’s adoption has grown rapidly, with millions of users preferring its bank-backed infrastructure.

Case Study: Regional Expansion Strategies

What distinguishes South American fintechs from many global peers is their ability to scale beyond national borders. While cultural and linguistic similarities facilitate expansion, regulatory differences often present challenges.

Nubank, originally Brazilian, entered Mexico and Colombia by replicating its simple, customer-first approach.

Ualá, born in Argentina, chose Mexico and Colombia as expansion markets to diversify away from Argentina’s unstable macroeconomy.

Fintual bridged Chile and Mexico through regulatory compliance and investor trust.

Movii and Addi are expanding from Colombia into Brazil and Mexico, where market sizes justify growth.

These examples illustrate how South American fintechs are evolving into pan-regional leaders, creating a more integrated financial landscape across Latin America.

Regional Trends Defining South American Fintech

By 2025, fintech in South America is not just about individual company success stories. It represents a structural shift in how finance operates across the region. Several overarching trends stand out as drivers of long-term transformation.

Financial Inclusion as the Core Mission

The single most important theme across South America’s fintech landscape is financial inclusion. From Nubank in Brazil to Ualá in Argentina and Movii in Colombia, nearly every leading company places inclusion at the center of its mission. This is not just a marketing slogan—it reflects a genuine effort to solve systemic problems.

Millions of South Americans lacked bank accounts a decade ago, and traditional institutions were often unwilling to lower fees or create accessible products. Fintech startups designed mobile-first platforms with low costs and intuitive user interfaces to reach these populations. The results are visible: by 2025, mobile wallet penetration in countries like Peru and Brazil has surged, and access to digital credit is expanding across Colombia and Argentina.

This commitment to inclusion has drawn attention from international investors and organizations such as the Inter-American Development Bank, which supports fintechs focused on financial literacy and microcredit.

Cryptocurrency and Digital Assets Adoption

Few regions in the world have embraced cryptocurrency with as much urgency as South America. Economic instability, inflation, and restrictive currency policies have driven widespread adoption of digital assets.

In Argentina, where inflation regularly exceeds 100%, stablecoins pegged to the U.S. dollar are widely used by individuals and businesses to preserve value. Startups like Belo and Lemon Cash facilitate easy crypto integration for everyday transactions.

In Brazil, exchanges like Mercado Bitcoin and Foxbit have become household names, trading billions of dollars annually.

In Colombia and Venezuela, remittances powered by crypto have provided critical financial lifelines for families separated by migration.

By 2025, many mainstream fintech platforms have integrated crypto features into their apps. Movii in Colombia and Ualá in Argentina allow users to buy and sell digital assets alongside fiat services.

For global investors, South America has become a testing ground for how crypto adoption can scale in challenging macroeconomic environments.

The Rise of Super Apps

South America is witnessing the convergence of financial services with lifestyle platforms, creating super apps that offer everything from payments to delivery, insurance, and loans.

RappiPay integrates finance into Rappi’s delivery ecosystem.

Mercado Pago links seamlessly with Mercado Libre’s e-commerce dominance.

Nubank is evolving toward a platform model, embedding partnerships with other financial and non-financial services.

This mirrors trends in Asia, where companies like Grab and WeChat pioneered the super app model. In South America, super apps are rapidly becoming the default way for consumers to manage both their money and their daily needs.

Green Fintech and Sustainability

As sustainability becomes a global priority, South American fintechs are beginning to integrate environmental considerations into their offerings. Known as green fintech, this emerging field combines digital finance with climate-conscious practices.

Some platforms are offering green loans that fund sustainable agriculture or renewable energy projects.

Investment platforms like Fintual are beginning to integrate ESG-focused portfolios, reflecting growing investor demand.

New startups are experimenting with carbon-tracking wallets that allow users to measure and offset the environmental impact of their purchases.

The potential for green fintech in South America is vast, given the region’s biodiversity, renewable energy capacity, and climate challenges. By positioning themselves at the intersection of finance and sustainability, fintechs can play a crucial role in aligning growth with environmental responsibility.

Regulatory Environment: Opportunities and Hurdles

Regulation has been both an enabler and a challenge for South American fintech.

Brazil’s Open Banking Revolution

Brazil has taken the lead by introducing one of the world’s most advanced open banking frameworks. By requiring banks to share customer data (with consent) across financial institutions, Brazil has created a level playing field for fintech startups to compete with legacy banks. This has fueled the growth of digital banks like Nubank and C6 Bank while increasing customer choice.

Colombia’s Sandbox Model

Colombia implemented regulatory sandboxes that allow startups to test innovative products under supervision. This flexibility has encouraged experimentation in areas such as cryptocurrency integration and digital lending, making Colombia one of the region’s most attractive destinations for fintech investment.

Argentina and Inflation Challenges

Argentina poses one of the toughest regulatory environments due to capital controls, high inflation, and strict foreign exchange regulations. While fintechs like Ualá and Mercado Pago thrive, they must constantly adapt to shifting rules. This volatility makes Argentina both a hub of innovation and a testing ground for resilience.

Chile’s Stable Framework

Chile’s regulators have maintained a stable, predictable environment, encouraging investment and long-term growth. This has made Chile a hub for wealth management and investment-focused fintechs like Fintual.

While progress is evident, fragmentation remains a challenge. Each country has its own rules, creating obstacles for companies seeking to operate regionally. Over time, regional harmonization may become a necessity to fully unlock the potential of South American fintech.

Green Finance Gains Traction: ESG investing and climate-focused financial products will grow as both investors and regulators demand sustainability.

Regional Harmonization: Efforts to unify fintech regulations across countries may emerge, creating a more integrated Latin American financial market.
