That migration you’ve been postponing? AI changed the math.
We modernize business-critical software — AI speed, senior engineers in control.
Book a Modernization ReviewThe system works.
Replacing it is still on the list.
- One person still understands it.
- Customers keep asking for the browser version.
- It only runs on an old Windows version.
- It’s built on a platform you wouldn’t choose today.VB6, Delphi, PowerBuilder, WinForms, Swing, MFC, Eclipse RCP, to name a few
But every estimate came back
too big to approve.
What changed the math
Writing the code again was the biggest line in your estimate. Today it is the smallest.
Agents do the volume.
- Rewrite the code, first pass
- Carry over simple screens and data access
- Read and document the source, checked by engineers
36,000 lines in under an hour.
In a case study on a VB6 ERP that is still in production, an agent rewrote twelve features in a single pass (Alves et al.).
But 30% of the behavior was missing.
The agent left out logic scattered across forms, settings and neighboring modules. The authors note that migrations with engineers in the loop tend to score higher.
Engineers do the hard part.
- Find every rule, written down or not
- Decide what the new system is built on
- Prove it behaves like the old one, rule by rule
Is this for you?
We are the right call if
- Your business depends on the system: you sell it, or you run on it.
- It needs a new architecture: desktop to web, client-server to services.
- Nobody can list everything it does, and the new system has to do all of it.
We are the wrong call if
- You need someone to keep the old system running as it is.
- The system is a mainframe, COBOL or SAP estate.
- A low-code tool would do.
If you are unsure, the review is where we tell you.
Book a Modernization ReviewHow it works
The old system stays live until the new one has proven it behaves the same.
Review: thirty minutes, free.
You describe the system, we say how we would approach it.
Assessment: two to four weeks.
Agents map the source, engineers track down the rules the agents miss. You get a migration plan and one module of your system, migrated and running.
Migration: module by module.
Tests pin down what the old system does today. A new module goes live once it passes them.
Handover: your team carries it on.
You get an agent-ready codebase: the knowledge and the checks that people and agents need to keep changing it are in the repository.
Google, Cursor and Arduino build on tools we started.
We have migrated desktop software to web technology and VS Code for years. Agents now do the volume, steered and checked by the kind of tooling we have built for a decade.

The people who do the work.
We dig into the problem before we solve it.
We take the time to learn your domain. Asking now is cheaper than refactoring later.
We deliver a first result you can see, fast.
You get a first version to judge for yourself. We fit into your process, or propose a roadmap.
We work side by side with you and your team.
You talk directly to the engineers who do the work, with one stable contact throughout.
We advise you honestly and build to last.
You’ll hear early what won’t work well, with an alternative. Tests matter as much as features.
»TypeFox has been an outstanding partner from day one. They are reliable, provide high-quality work and are easy to interact with. The collaboration has been excellent, and we look forward to continuing to build on it.«
