The world's largest independent digital bank
HQ: São Paulo, Brazil | Founded: 2013 | Employees: 8,000-9,500 | Stage: Public (NYSE: NU) | Website: https://www.nubank.com.br
Nubank (legal name Nu Holdings Ltd.) is a Brazilian neobank founded in 2013 by Colombian Stanford MBA David Vélez, Brazilian engineer Cristina Junqueira (ex-Itaú), and American computer scientist Edward Wible (ex-Princeton, Sequoia-scouted CTO). Frustrated by Brazil's concentrated, fee-heavy banking oligopoly, the trio launched a no-annual-fee international Mastercard managed entirely via mobile app on California Street in São Paulo's Brooklin district. From a single credit card, Nubank expanded into NuConta digital accounts (2017), personal loans (2019), business accounts, insurance, and Easynvest (rebranded NuInvest) brokerage, reaching 34M customers by Jan 2021 and 131M by Dec 2025 across Brazil, Mexico and Colombia. Regulated by the Central Bank of Brazil and listed on NYSE and B3 in Dec 2021, it is the largest fintech bank in Latin America and the most downloaded banking app in the region.
Nubank's model combines a proprietary, cloud-native core banking stack with AI-driven credit underwriting (NuFormer) and a fanatically low-cost operating platform: monthly average cost-to-serve per active customer is ~$0.8-$1.0, efficiency ratio ~19.5%, and monthly ARPAC reached $17.1 in Q2'26. Revenue is diversified across credit ($3.6B), float ($1.45B) and fee income ($0.8B) in Q2'26, with a $39.4B credit portfolio and $45.3B in deposits. The company has been profitable since 2023, posting $2.87B net income in FY'25 (33% ROE), and trades at ~22x forward P/E with $41.9B deposits and $8.9B total capital.
Nubank has built the dominant digital banking franchise in Latin America, scaling to 138.9M customers, $16.3B in 2025 revenue and $58B market cap by replacing Brazil's oligopolistic banks with a no-fee, mobile-native platform. Its fee-free purple Mastercard, NuConta, and AI-powered NuFormer underwriting create a low-cost advantage ($0.8-1.0 cost-to-serve per active customer) and 33% ROE. With Berkshire, Sequoia, Tencent and Tiger backing, Nubank IPO'd at $41.5B in Dec 2021 after a $30B private round, and is now expanding from credit-led neobank to full-stack bank in Brazil, Mexico and Colombia — with a conditional US national bank charter (Jan 2026) as the next frontier.
