About Nubank
Tackling the complex banking system to empower people in one of the most bureaucratic markets in the world seems like a crazy idea, right? But that's why, how, and where Nubank was born. We fight complexity through our transparent and straightforward products and experiences: a no-fee credit card, a rewards program, a lending platform, and a digital savings account. In a nutshell, we are the most innovative tech company in Latin America, and we are obsessed with building financial services and products that make our customers love us fanatically. With over 40 million customers and $2 billion raised in investment rounds, we are the fastest growing digital bank in the world, with offices in Brazil, Colombia, Germany, Mexico, the US, and Argentina. And it's still only Day One for us!
