Brazil's Nubank Uses CockroachDB for Application Resiliency & Scale

Nubank, a leading Brazilian financial technology company valued at $35 billion, has chosen CockroachDB as the scalable SQL database for its critical credit card authorization service. As Nubank's business rapidly grew from 12 million customers in 2019 to 40 million in 2021, it needed a more scalable solution that would not rely so much on memory and enable the company to keep growing. The Nubank Authorizer team chose CockroachDB due to its ultra-resilience, simple scalability, strong consistency, and easy maintenance.
