About Nubank

Nubank was founded in 2013 to free people from a bureaucratic, slow and inefficient financial system. Since then, through innovative technology and outstanding customer service, the company has been redefining people's relationship with money across Latin America. With operations in Brazil, Mexico and Colombia, Nubank is today the largest digital banking platform in the world outside of Asia and one of the leading technology companies in the world, reinventing over 40 million customers' financial lives.

 

Nubank achieved this by offering a no-fee credit card, entirely managed by a mobile app, and a digital account, free of taxes. Nubank also offers transparent and hassle-free personal loans, a business account tailored for SMBs, and life insurance. In 2020, Nubank acquired digital broker Easynvest, now called Nu invest, and became the leader in self-directed digital investments in Brazil. 

 

Throughout the years, Nubank raised around US$2 billion with some of the best-known growth and technology investors in the world, such as Berkshire Hathaway, Sequoia, DST, Tencent, Tiger, Kaszek, Founders Fund, Dragoneer, TCV, Redpoint, Ribbit, GIC, Whale Rock, Invesco, QED, and Capital Group.

 

Today, Nubank is a global company, with offices in São Paulo (Brazil), Mexico City (Mexico), Buenos Aires (Argentina), Bogotá (Colombia), Durham (United States) and Berlin (Germany). Nubank was founded in São Paulo by Colombian David Vélez, and cofounded by Brazilian Cristina Junqueira and American Edward Wible. For more information, visit www.nubank.com.br.
