Splunk is Nubank’s “one-stop shop” for IT monitoring and business needs. As a digital-only bank, Nubank requires a unique approach to help ensure it can operate without physical locations to save its customers time and reduce bank fees.

From service logging to security and compliance, Splunk provides Nubank with the information needed to derive insights regarding how systems are operating and how services are delivered to customers.

“It’s estimated that Nubank customers have avoided paying $4.6 billion in bank fees and saved 113 million hours in wait time and Splunk Cloud Platform has been essential in providing us the flexibility and agility to react to customer needs quickly,” continued Swann. 

Nubank also leverages Splunk’s workload pricing to meet growth projections and budgetary goals by right-sizing their rate of ingest. Workload pricing has offered flexibility and adaptability as the company continues its rapid expansion and support its customer base.
