Catalio is an AI-powered documentation and change management platform built for enterprise teams modernizing complex legacy systems.

The engineers who built your most critical platforms are retiring. The business logic that makes those systems work, 30 years of decisions, exceptions, and rules, was never written down. When that knowledge walks out the door, migrations stall, AI tools amplify every wrong assumption, and programs fail for the same reason every time.

Catalio fixes the root cause. We connect to your legacy systems, custom platforms, and business SaaS applications, and automatically extract business rules, requirements, and architectural decisions using AI. The result is a living specification: structured, confidence-scored, and always up to date.

Our platform helps teams:
• Extract institutional knowledge from code, documents, and SMEs, not just one source
• Create living specs so every migration starts from a complete, verified picture
• Plan and deliver change with full traceability from capabilities to shipped code
• Feed AI coding tools the structured context they need for accurate, policy-compliant outcomes

Native support for Salesforce, ServiceNow, and NetSuite, plus any legacy system with APIs or metadata access. Built by enterprise veterans who have led these programs and know what fails.

You cannot modernize what you cannot explain. Catalio makes sure it's written down.
