FIG 01SYS.DISCOVER
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
.
FIG 02SYS.Integrate
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.
FIG 03SYS.rebuild
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.
