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

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