Purpose built for safe modernization - from legacy to AI
Tangible business value at every step
Big Bang Risks
Prove success on one process at a time - no all-or-nothing cutover, no downtime to mission-critical systems.
Faster Time-to-Market
Generate production-ready APIs and services in days, not the months a mainframe team usually needs.
Cost Reduction
Reuse your existing business logic instead of rewriting it — cutting legacy integration and mainframe costs
Context Reduction

A proven path to modernization -
one business process at a time
Reverse Engineering
Pick a business process and point us to the sources. We discover everything at the source - apps, dependencies, data and screens - then auto-generate a full spec: workflow, business rules, data models and roles.
Smart Integration
Expose your legacy functions as governed APIs, and simulate every change to validate it before anything moves. Legacy and modern systems keep running side by side - coexistence with zero disruption.
Forward Engineering
Rebuild into your target platforms and cloud services. Choose your approach (reimagine, refactor or replatform), your platform and your LLM - no vendor lock-in.
