Architecture audit
Independent read on the existing system. We document what's there, name the risks (scalability, security, hiring, vendor lock-in), and deliver a sequenced modernisation roadmap. Typically 2–4 weeks.
Mittelstand · Modernisation
Modernise legacy systems without a full rewrite
Established German companies don't need a Silicon-Valley-style ground-up rebuild — they need a phased modernisation that keeps the business running. We replace load-bearing parts of legacy stacks while operations stay live.

Engagement formats
What we build
Modernisation work usually starts with one of these four engagements:
Phased system replacement
Strangler-fig migration: the legacy system keeps running while we build the new one beside it. We move traffic over module by module — billing first, then operations, then reporting — without a production freeze.
Internal platform rebuild
Internal dashboards, admin tools and operator surfaces that your team uses every day. Often the highest-ROI work because productivity gains compound.
Cloud migration with a plan
Out of an on-premise data centre or off a single-vendor cloud. We define target architecture, dependency mapping, cost model, migration waves and a cut-over plan you can present to leadership before we start.
Audience
Who this is for
We're a fit when:
- Your software was built 8–20 years ago and now slows the team down
- You can't hire enough senior engineers locally to do this in-house in time
- A full rewrite has been considered — and rejected — because the risk is too high
- Operational data integrity matters: customers, contracts, financial records
- You report to leadership that wants milestones, budgets and a phased plan, not 'we'll see'
Not a fit if you're greenfield with no existing system, or if leadership has already committed to a full rip-and-replace under fixed timeline.
Outcomes
What you walk away with
- 01A documented modernisation plan you can defend to a board or owner
- 02A working migration that runs in parallel with the legacy system
- 03Reduced reliance on individual engineers who hold tribal knowledge
- 04Operational continuity through every migration phase — no freeze, no big-bang launch
