Kathalyst uses AI-powered documentation to reveal the business logic behind your legacy systems — then helps you transform that understanding into modern applications. Let’s make mainframe modernization fast, feasible, and fail-proof.
But here’s the hard truth: None of it works unless you truly understand how your legacy systems actually run.
Kathalyst creates rich, AI-generated documentation that decodes your applications then leverages that knowledge to help modernize your systems, so your team can transform with clarity, not guesswork.
Mainframe experts are retiring fast. COBOL developers are scarce. Culture gap is a real barrier; so training modern teams to reverse-engineer legacy systems doesn't scale.
Hiring outside experts often means handing over critical business logic. Plus, you are paying a premium for knowledge that may never come back.
Old systems mean millions in software license fees, plus hidden infrastructure costs and operational drag.
