A2Z Fintech

The US banking fortress just got a new neighbor. NuBank—the Latin American titan with 127M+ customers—has officially announced its US National Bank License.

In this minisode, Aman and Zubin break down why this isn't just another fintech launch. We explore the "Wayne-dependent" reality of US regional banks stuck on 1980s COBOL code and why NuBank’s $1 cost-to-serve makes them a lethal competitor to the "Hollow Middle" of American finance.

Highlights include:
  • The COBOL Crisis: Why US regional banks are being held hostage by 40-year-old software.
  • Hard Mode Mastery: How NuBank conquered Brazil and why that makes the US market look like "Easy Mode."
  • Focus vs. Breadth: Why NuBank is succeeding where Revolut is still fighting for regulatory ground.
  • The Death of the Legacy Tax: What a cloud-native "siege engine" means for your wallet.
