We've spent 25+ years modernizing legacy systems for hundreds of companies. We've codified everything we've learned into an AI-first process that automates analysis, conversion, and testing — while guaranteeing that every line of business logic is preserved and validated.
Most modernization approaches fall into one of two traps:
Fast but dangerous. LLMs hallucinate. Business logic gets lost. You can't trust the output without exhaustive manual testing — which defeats the purpose.
Safe but impossibly slow and expensive. You're paying humans to do what a machine should do.
We engineered a third path. AI where AI excels — pattern recognition, idiomatic code generation, architectural insight. Deterministic rules where correctness is non-negotiable. Every transformation validated against a test plan derived from the original application's behavior.
No phase skipped. No shortcuts taken. Every step exists because we've seen what happens when it's missing.
Everything starts with the analyzer. Before a single line of code is touched, we generate a complete technical and business report of your application — automatically.
We don't just modernize code — we modernize behavior. Our process extracts the actual business rules and functional behavior from your legacy system, creating a living specification.
Testing is the most critical phase of any modernization. We generate tests before writing a single line of new code — so we can validate that every behavior is preserved.
Our conversion engine combines AI with deterministic rules — giving you the speed of AI with the correctness of deterministic transformation.
Every converted module is tested against the test plan generated in Phase 3. Humans review failures — not successes. This means our team focuses their time where it matters.
We don't just translate your old code into new syntax. We use the modernization as an opportunity to build an architecture that serves your users and your business for the next 20 years.
We are AI-first. But AI-first doesn't mean AI-only.
Large language models are trained to produce plausible output — not correct output. In a modernization context, a hallucination isn't a funny mistake. It's a bug in your billing system, your inventory logic, or your compliance reporting. Our rules engine catches these before they reach production.
The logic in your legacy system represents decades of decisions, edge cases, and regulatory compliance. It may be ugly, but it's correct. Our process treats business logic preservation as a hard constraint — not a best effort.
We generate tests from your legacy code before conversion. That means we validate the new code against the old behavior — not against what we think the behavior should be. If a test fails, the code doesn't ship. Period.
Our team has been modernizing legacy systems since before "digital transformation" was a buzzword. We've seen every pattern, every antipattern, and every migration pitfall — and we've built our process to avoid them.
"We've worked with companies ranging from 10-person startups to Fortune 500 enterprises. The one thing they all have in common: mission-critical legacy systems that power their business, and a need to modernize without stopping the business. That's exactly what our process is designed for."
