Unlock Digital Innovation in Banking

The Challenge

Over the last few years, new digital-only banks have taken trillions of dollars in checking accounts, mortgages, and wealth management assets from traditional banks. How can banks tied to mainframe systems keep up with their digitally-native competitors?

The Solution

Composable banking is the answer. Composable banking is the ability to rapidly assemble new banking products and customer experiences from cloud-native building blocks. OpenLegacy transforms the way banks innovate by finally making composable banking a reality.

The Fastest Path to a Composable Bank

OpenLegacy connects directly to core systems, automatically generates digital-ready code, and deploys as standard microservices or serverless functions. With OpenLegacy, banks can finally achieve the speed and resilience of the composable enterprise — harnessing legacy assets for continuous innovation.

"OpenLegacy helps us set the mainframe free, finally. Instead of being a prohibitive factor for new projects, it’s now the enabler - with OpenLegacy generated APIs that connect to any other system in our environment”

“OpenLegacy helped us become truly responsive by letting us build APIs and microservices in a single sprint—five microservices in two weeks, instead of one in many months.”
