The best engineers you can put on a legacy system

Our engineers have shipped production software for more than 25 years and have dozens of migrations behind them. Send us your system today: a fixed price in 48 hours, production in 30 days.

What we do

We take a codebase in COBOL, RPG, VB6, Delphi, ColdFusion, PHP, Java or Oracle PL/SQL and return the same behavior in Go, Rust or TypeScript on PostgreSQL. It moves over module by module, with tests written against how the original actually behaves. Every language, every database and every size is in scope. The map of the system comes with the work, and for code this old it is usually the only accurate one anybody has.

Where the platform came from

We built the platform because the alternative was reading a million lines by hand. Our models are fine-tuned on paired legacy and modern code, and they run inside a harness that parses the source into a dependency graph and plans the order of work from it. The harness writes the tests before the code and holds a module back until its outputs match the original on the same inputs.

Why we sell a finished system

An agency sells hours and staffs them against your backlog, so a rewrite that runs eighteen months is a good year for them. We sell the finished system at a fixed price and deliver it inside 30 days. The platform makes that arithmetic work, and engineers with 25+ years make it hold. A job that seems to need twelve people for a year was scoped wrong.

How we finish in 30 days

The platform does the reading. It parses the whole tree, every language in it at once, and hands our engineers a dependency graph, a dead-code list and the places where the business rules actually live. That used to take a team a quarter. It takes us 3 days, which is why 30 days is a date in the contract. Where the work is regulated, the models run air-gapped inside your perimeter, on your hardware or on ours.

Who you talk to

The engineer who answers your first message is the one who reads your code, with 25+ years of production software behind them. There is no account manager in between and no discovery call whose only purpose is to book a second call. Get a quote today and talk to that engineer tomorrow.
