Nubank nuFormer AI Model Powers Credit Policy and AI-First Expansion

Nubank developed nuFormer, a proprietary AI model for analyzing customer behavior. One application enabled Nubank to adjust credit card limit policies in Brazil, allowing the bank to expand credit for qualifying customers without sacrificing its overall risk attitude. The company is also pursuing agentic workflows across most products and services to improve customer experiences. Nubank serves 127 million customers across Latin America, including 13 million in Mexico (about 14% of the country's adults) and approaching 4 million in Colombia, with the majority of customers in Brazil. The neobank describes itself as an 'AI-first' company: new AI use cases and tools go through an internal committee and then compliance review, and employees may use only tools the bank has licensed so that customer data stays private.
