Legacy modernisation — architecture migration without big-bang risk

Situation 01

Your software comes from a different era.

You run software that has carried your business for years — order processing, inventory, time tracking. Often on-premise, organically grown, hard to maintain. Nobody on your team wants to touch it, every change becomes expensive. You know it'll eventually tip over — and modernisation won't happen on its own.

How we help

We modernise legacy software without big-bang risk. First an architecture analysis, then a joint migration plan, then incremental delivery — the old system keeps running while the new one takes over piece by piece. You keep operating, regain maintainability, and lay the foundation for the next 15 years.

How we did it with Omniga

Migration of a heterogeneous application landscape from .NET Framework 4.6 to .NET 8 — across multiple business-critical applications, with zero downtime for the customer-facing SaaS platforms.

Custom software development — from idea to cloud-native SaaS platform

Situation 02

You have an idea. What's missing is the team to build it.

You see a market opportunity. You know software is the lever. But you don't have your own developers — and building an internal team means recruiting, hiring, onboarding risk, long-term commitments. What you need is a partner who takes your idea from sketch to working software — flexibly, transparently, without locking you into fixed costs.

How we help

From first concept to production SaaS — we deliver the full path. First a fixed-price Discovery, then a Werkvertrag based on the backlog. We start with a compact MVP, get real users on early, then scale with your needs. Your idea, our team, a clearly defined scope.

How we did it with MOBEX

From idea to cloud-native SaaS platform: architecture, security, microservices backend on Azure. In parallel we trained MOBEX's existing team in the new technology — engineers from a PHP background with no prior experience in modern microservice architectures who today develop the platform independently.

Strategic technical guidance — technical lead and sparring partner in your project

Situation 03

Your team is building — but who owns the architecture and direction?

Your internal team is good and ships. But there's no one who owns the overall architecture, makes technical decisions on solid ground, and translates between management and the team. Without that leadership, a project can drift in the wrong direction — often only visible once it gets expensive.

How we help

We accompany your team as a technical lead and sparring partner — and we build hands-on, from concept to delivery. We own architecture and direction, build alongside you at the critical points, and act as the bridge to management. Not interchangeable body-leasing by the hour, but expertise across the whole lifecycle.

How we did it with MOBEX

At MOBEX we took overall technical lead and developed the cloud-native platform together with the MOBEX team — actively building across all areas, from backend and CI/CD to Infrastructure as Code and security. The managing director calls us a “strategic technology partner on eye level.”
