Your software runs fine. We extract what it knows and rebuild it audit-ready.
Legacy business applications rarely fail because of what they do. They fail audits: unsupported base software, knowledge held by one person, recovery never tested. We turn the existing application into a written specification and rebuild it incrementally on a supported stack, while the business keeps running.
Same business. A completely different footing.
Three findings in almost every legacy audit. And how they disappear.
- Base software without vendor supportEnd-of-life components, no security updates, no patches, and compensating controls usually missing.A supported, current stack, migrated incrementally while the old system keeps running.
- Operational knowledge held by one personThe system runs because one person keeps it running. Vacation, resignation or retirement becomes a business risk.We extract the business logic into a written specification, AI-assisted, review it with your experts, and keep it versioned with the code.
- Recovery never testedBackups may exist. Whether they can be restored has never been proven.Automated backups with tested, provable recovery, and monitoring that makes incidents reportable on deadline.
First the specification. Then the software.
The most expensive part of modernization was never writing new code. It was understanding the old one. We apply AI exactly there, and it is why a rebuild that never justified its budget is back on the table.
Extract
We read your entire existing application, assisted by AI, and extract the business logic: rules, workflows, edge cases. Many clients see for the first time, in writing, what the system actually does. For a large system this is a project of its own; the assessment tells you how large.
Review together
We walk through the specification with you, in business language, not code. You decide what the new system keeps, fixes or drops. We prepare the material; you make the decisions.
Rebuild in iterations
We develop against the agreed specification in 2-3 week sprints. Every release is measured against a specific version of the spec, tested and reversible. The legacy system keeps running until its replacement is proven.
Prove and hand over
The specification is kept under version control alongside the code, so documentation and audit evidence are always current. The new system is fully owned by your team. Or we keep running it for you under an SLA.
On your terms, on European soil.
Public cloud
EU regions on Azure or AWS by default. Lower fixed cost, elastic capacity, everything in infrastructure as code.
Your environment
Regulated, air-gapped or on-prem requirements? We deploy to infrastructure you control.
EU data residency
An EU-based team, EU regions by default. US standards such as HIPAA and FedRAMP when you need them.
Systems we have already moved.
What you can count on.
A written analysis of your situation: the most likely risks and audit gaps, a rough effort range, and the most sensible next step. Free, within 2 business days, from the founder personally.
No. Two or three sentences about your application are enough: technology, rough age, industry. Everything else comes later, if you want it to.
It depends on the system. A small tool takes weeks; a large platform can take months of extraction and workshops. The assessment gives you a realistic range instead of a fortnight promise.
The assessment costs nothing. Delivery is priced to fit your governance: fixed-price phases, sprint budgets or time-based, agreed up front. If modernization does not pay off in your case, that is what we will write to you.
NDA on request up front, we also sign your template. GDPR-compliant processing in the EU, no sharing with third parties.
