Every enterprise is racing to deploy AI. But the business logic and data that would make that AI valuable - decades of your most validated rules and richest records - are locked inside mainframe and IBM i systems it can't reach. Those systems aren't a liability. They're a refined asset. They just can't talk to the AI your board is now asking for. OpenLegacy changes that. We're the AI-driven platform that takes enterprises from legacy to AI, one business process at a time - creating the foundation enterprise AI needs to scale. Start wherever the value is highest. Make your most complex legacy systems instantly accessible to enterprise AI and agents - exposing only what the AI needs, so it stays accurate and affordable. Or go all the way: full modernization into any platform -cloud, Salesforce, Pega, Java/.NET, or your own stack. Or land anywhere in between, and expand as your goals grow. The difference is the method. We work one business process at a time, so every step is proven and reversible. Legacy and modern systems run side by side in full coexistence - no big-bang cutover, no downtime. What enterprises see: • 10x faster time-to-market - production-ready APIs and services in days, not months • 60% lower cost - reuse your business logic instead of rewriting it • 99% less AI context - expose only what agents need to stay accurate and cheap to run • Zero big-bang risk - coexistence and continuous operations throughout Integration tools connect your legacy.
