Untangle legacy systems
From the smallest targeted fix to a complete rebuild, we get you out of the expensive legacy system — controlled, documented, without halting day-to-day business.
The system nobody wants to touch
The expensively bought shop. The grown solution nobody fully understands anymore. It still runs — but every change is a risk, the knowledge sits in a few heads, the licenses keep costing, and to AI the system is a locked room. That is where we start: untangling legacy is the companion on the road to AI-readiness.
Three stages, one principle: adapt → modernise → replace
- Adapt. The smallest intervention that shows impact — targeted, with a safety net, without destabilising the system.
- Modernise. Add interfaces, build documentation, tests as a contract — the system becomes manageable again, and operable by AI along the way.
- Replace. When it pays off: the controlled rebuild, audit-proof with Coautra — every change a reviewed, documented step instead of a big-bang bet.
Proof, not promises
Immotron, a complete real-estate platform in production, was built end-to-end with our audit-proof process — over 1,700 merged changes, each documented and reviewed. The full field report is on the blog — including what went wrong.
It stays honest
Not every legacy system should be replaced. Sometimes the small targeted fix is the economically right answer — and we say so before a project is born. A conversation, not a sales funnel.
Pricing
Guide rate CHF 250/h · fixed-price packages · success component available for measurable goals
Wherever the scope is plannable, we prefer fixed-price packages — you know before the start what it costs. For measurable goals, a success component is possible; the KPI for it is agreed in writing upfront. The guide rate applies to everything that cannot sensibly be packaged.
