Case Study: Banking and Financial Services Holding Company achieves 70X faster API performance with OpenLegacy

Leading bank partners with OpenLegacy to realize vision of agile innovation, while improving performance 70X

Banking and Financial Services Holding Company, a large, long-established bank serving more than 27 million customers, wanted to accelerate its customer-first digital transformation and deliver seamless omnichannel experiences. A key challenge was modernizing legacy mainframe-based onboarding and other customer workflows so they could support faster, simpler service for millennials and other customers without waiting on slow, decades-old systems.

The bank partnered with OpenLegacy to expose mainframe workflows as APIs. OpenLegacy helped deliver the first API in hours and additional APIs quickly after, using a direct-to-mainframe architecture with no ESB or middleware layers. The result was a 70X improvement in transaction response time, faster development and deployment, lower costs, and a more agile path to launching new digital services.
