Your legacy modernized in weeks, not years.
VB6, COBOL, RPG/AS400 → modern production code. ~96% demonstrated equivalence, module by module. You pay for the result, not the consumption.
~96%
functional equivalence demonstrated
module by module, Viseo test methodology
~85%
less expensive than commercial LLMs
via FRIO technology, depends on volume and mix
Fasteer Factory consolidates Smart Analysis, Smart Modernization, and Smart Maintenance. You don't need three separate products and three separate contracts.
Map, understand, and document your codebase before any decision. Dependency map, effort estimate, risk areas.
Convert VB6, COBOL, RPG/AS400 to modern stacks with verified functional equivalence, module by module.
Keep the modernized code healthy: continuous monitoring, CVE alerts, dependency management, drift detection.
Assessment at fixed price → PoC on a pilot module → Incremental rollout per module / per KLOC. You decide whether to continue after each step.
Legacy map, dependencies, dead code, module-by-module effort estimate. Black on white perimeter — before any commitment.
One real module transcoded with demonstrated equivalence. Proof before rollout — not a presentation, a working module.
Incremental rollout, one module at a time. Price per module or per KLOC, with bands by complexity. You pay for the result, not the consumption.
Functional equivalence is demonstrated module by module using the Viseo test methodology. The team reviews and approves each part before going to production. ~96% — not a claim, a measurement.
Visual equivalence test: input/output comparison
Human review and approval at each module
Full audit trail of the entire modernization
~96% equivalence (depends on language and complexity)
The economics of modernization — before and after AI
Depends on volume, language and complexity.
Language, LOC, business constraint — that's all we need. Assessment in 48 hours.
