The 80% Brazilian banking-market concentration figure is widely cited but reflects estimates of total deposits, credit, and accounts; exact share figures by product vary across sources. The IPO valuation of $45 billion is from the first day of trading; the stock’s subsequent performance has been substantially above the IPO price. ## Where Brazilian banking was in 2013 Brazilian retail banking in 2013 was structurally concentrated: Banco do Brasil, Itau Unibanco, Bradesco, Santander Brasil, and Caixa Economica Federal together controlled approximately 80% of the market by deposits, credit, and account relationships. The structural concentration produced predictable consumer-facing problems: account fees that ranged from R$30-50/month for basic checking; credit cards with effective interest rates above 200% APR; account-opening processes that could take weeks; and branch-based service models that excluded customers in lower-income tiers and remote regions. The digital-banking products of the incumbents were generally weak. David Vélez moved to Brazil in 2012 as Sequoia’s partner setting up the LatAm office. After 18 months of trying to make consumer-credit and banking investments and failing to find founders he was willing to back, he decided to build the company himself. He recruited Cristina Junqueira (formerly at Itau) and Edward Wible as co-founders, and launched Nubank in 2013. The thesis was specifically that a mobile-first, no-fee credit card could acquire a substantial customer base in the consumer-credit underserved segments of the Brazilian market. ## The product expansion Nubank launched its no-fee Mastercard credit card in 2014 with mobile-first onboarding and customer service. The purple plastic became visually distinctive and the product earned strong word-of-mouth in the early-adopter segments. Customer growth was strong from 2014-2018, scaling from tens of thousands of card users to several million. In 2017 Nubank expanded into a digital-checking account (NuConta), and over the following years added savings products, consumer loans, business accounts, life insurance, investment products, and cryptocurrency services. The expansion from credit card into broader banking products was the operational transformation that made the long-run economics work. The credit card business alone would have been capital-intensive and competitively contested; the broader banking platform allowed Nubank to monetize lower-cost-of-funds deposits, to cross-sell adjacent products, and to lower its cost-of-customer-acquisition (existing customers who add second and third products do not require new acquisition spend). By 2024 the platform was operating across Brazil, Mexico, and Colombia, with each market in a different stage of customer-acquisition maturity. ## The IPO and the profitability inflection Nu Holdings IPO’d on the NYSE in December 2021 at approximately $45 billion valuation. Warren Buffett’s Berkshire Hathaway had invested $500 million in a pre-IPO round earlier in 2021, providing a notable validation from a value-oriented investor known for skepticism of high-growth fintechs. The IPO came at a relatively high valuation against a still-loss-making business; the public-market valuation declined substantially through 2022 as growth-equity multiples compressed. The 2023 inflection was when Nubank crossed sustained profitability. 2023 net income exceeded $1 billion, with the trajectory accelerating into 2024 ($1.9 billion net income on $11.5 billion of revenue). The profitability came from several factors compounding: maturation of the Brazilian customer base toward higher-revenue product-bundle relationships, scale economics on operational costs (Nubank’s cost-to-serve per customer is reportedly a fraction of incumbents’ cost), and the credit business reaching equilibrium between portfolio growth and loss-provision cycles. The stock recovered substantially in 2024 as the profitability inflection became visible. ## How RGM thinks about challenger-bank strategy When clients in fintech, banking, or international markets ask about how to build a challenger bank business at scale, Nubank is the structural example we point to. Three structural lessons. First, the target market matters — Brazilian retail banking in 2013 had unusually large gaps in fee structure, product quality, and digital experience that made customer acquisition possible at low cost. Challenger banks in mature retail-banking markets (UK, US, Germany) face structurally harder competitive dynamics because the incumbents are more competent. Second, the product roadmap from single-product (credit card) to platform (full banking) is what produces the long-run economics; challenger banks that stop at a single product face hard limits on unit economics. Third, the path to profitability takes a decade — Nubank was loss-making from 2013-2022 and only crossed sustained profitability in 2023, ten years after founding. Investors and operators who require shorter time-to-profitability paths should not start challenger banks; the capital intensity and customer-acquisition timeline does not support compressed timelines. The pattern is generalizable to other regional challenger-bank opportunities and to other consumer-financial-services categories where incumbents are structurally underperforming the digital-product bar. We tell clients in these categories that the prerequisite conditions are (a) incumbents who are substantially worse than the achievable product bar, (b) a decade of patient capital, and (c) a founder-led organization that can sustain the long execution timeline. Without all three, challenger-bank trajectories tend to stall before reaching the platform-economics inflection. ## Frequently asked questions How does Nubank make money? Nubank’s revenue comes from three principal sources. First, credit interest and fees on the credit-card and consumer-loan portfolio (the largest revenue line). Second, interchange fees on debit and credit card transactions. Third, fees on adjacent products (life insurance, investment management, business banking, mobile recharge, gift cards, etc.). The product-mix has shifted over time as the broader-banking platform has expanded; the credit-card-only model of the early years has evolved into a multi-product platform with diversified revenue streams. How does Nubank compete with incumbent Brazilian banks? On cost (no monthly fees vs R$30-50/month at incumbents), on digital experience (mobile-first onboarding and service vs branch-and-phone at incumbents), and on credit access (Nubank serves customer segments that incumbents underwrote less aggressively). The incumbents have responded with their own digital products (Itau’s iti, Banco do Brasil’s digital initiatives), but the response has been slower and less complete than Nubank’s offering. The competitive dynamic is more about Nubank taking customer growth as the underlying market grows than about Nubank displacing incumbent customers wholesale. What is the strategy for Mexico and Colombia? Mexico (entered 2018, ~10 million customers by end-2024) and Colombia (entered 2020, ~2 million customers) are structurally similar markets to Brazil — concentrated incumbent banks, large unbanked or underbanked populations, mobile-first consumer segment. Nubank is repeating the Brazilian playbook (credit card, then deposit account, then expansion) in each market with adaptations for local regulatory and product specifics. The Mexican expansion is approaching the inflection point where Mexican customer-base unit economics will start contributing meaningfully to total profitability. Colombia is earlier in the same trajectory. Is Berkshire Hathaway’s investment validation strong? Yes, with caveats. Berkshire Hathaway invested $500 million in Nubank in June 2021 at approximately $30 billion implied valuation. Buffett and Munger have historically been skeptical of high-growth tech-fintech investments, so the Nubank investment was notable. Berkshire has held the position through the post-IPO volatility, which signals continued conviction. The investment is not enormous on Berkshire’s scale (much smaller than Apple, BofA, AmEx) but is meaningful for the signal it sends about fundamental business durability. Can Nubank expand outside Latin America? Probably not without strategic rethinking. The Brazilian / Mexican / Colombian opportunity comes from a specific combination of market structure (concentrated incumbents), demographic conditions (large mobile-first customer segments), and regulatory environment that does not transfer to North American or European markets. Asian markets have their own well-established mobile-banking ecosystems (Tencent, Alibaba, Kakao). The most likely path is continued LatAm expansion (Peru, Argentina, Chile candidate markets) rather than transcontinental expansion. ### Sources & references - [Brazil’s Digital Banking Platform Nubank Reports Steady Revenue Growth, $1.36B In Q4 Gross Profits (Crowdfund Insider)](https://www.crowdfundinsider.com/2025/02/236611-brazils-digital-banking-platform-nubank-reports-steady-revenue-growth-1-36b-in-q4-gross-profits/) — Crowdfund Insider coverage of the 2024 full-year results. - [NuBank Revenue and Usage Statistics (Business of Apps)](https://www.businessofapps.com/data/nubank-statistics/) — Aggregated metrics on Nubank’s customer base and revenue. - [David Vélez (Wikipedia)](https://en.wikipedia.org/wiki/David_V%C3%A9lez) — Background on the founder and the company’s origin. - [Nubank (Wikipedia)](https://en.wikipedia.org/wiki/Nubank) — Aggregated reference for company history and product timeline. - [Nu Holdings Ltd. 6-K filings (SEC EDGAR)](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001691493&type=6-K) — Nu Holdings’ primary disclosures including quarterly results and customer-count metrics. ## Related [#### All case studies The full case-study library.](/learn/case-studies/)[#### MercadoLibre LatAm A related LatAm platform with overlapping fintech operations.](/learn/case-studies/mercadolibre-latam-ecommerce-2014-2024/)
