Koto has refreshed Nubank's global identity ahead of its US expansion, creating a flexible brand system designed to accommodate more than 140 million customers and an expanding portfolio of financial products. The redesign retains the recognizable Nu logo while refining its signature purple, introducing proprietary Nu Sans Display and Nu Sans Text typefaces, and establishing a global library of photography, illustration, and motion assets. The system also extends into conversational AI, in-app animations built with Rive, and a redesigned global website, bringing greater consistency to Nubank's growing international presence.
