David Vélez founded Nubank in 2013 after a deeply frustrating experience trying to open a bank account in Brazil, eventually growing it into one of the largest digital financial institutions in the world. Before starting the company, he worked in venture capital at Sequoia, a background that heavily shaped his views on market scarcity, talent evaluation, and corporate culture. This compilation organizes his practical operating insights on competing against entrenched monopolies, earning customer trust, and leading a rapidly scaling organization.
