Wells Fargo, the world's second-largest bank by market capitalization and the fourth largest bank in the U.S. by total assets, uses Couchbase to support its fraud monitoring infrastructure. High performance, high availability, and easy scalability help Wells Fargo monitor each and every transaction for fraud at less than 10 ms per operation for 9,000 reads and writes per second.

“We have a lot of data in Oracle, which is mainly used for reporting purposes. But the heart of the data – where the decisions are made – is in Couchbase because that is where high-performance throughput is needed.”
