CTO-level guidance, without hiring a CTO
From Munich: a senior technology lead at your side for a day or two a month — for architecture decisions, a roadmap that holds, and infrastructure that does not quietly get expensive.
Technology decisions compound. Most companies notice too late that nobody senior was in the room when the stack was chosen — and then pay for it for years. We fill that seat part-time: honest, vendor-neutral advice from people who still build software themselves.
The challenge
Without senior technical guidance, it is easy to pick the wrong stack, accumulate technical debt or over-spend on infrastructure — mistakes that cost far more to fix later than to avoid now.
What you get
- Fractional CTO — a senior technology lead one or two days a month
- Architecture and roadmap reviews of what you already have
- Cloud, DevOps and scalability assessments
- A second opinion on a decision, a stack or a supplier
Typical results
- Confident technology decisions, fewer costly mistakes
- A clear, prioritised roadmap
- Senior CTO-level guidance without a full-time hire

From a decision nobody wants to make to a roadmap you can work through
Left, the situation most companies are in when they call. Right, what changes once someone senior is accountable for the answer.
The question goes up and comes back unanswered, the systems grew into each other as they arrived, and every item carries the same flag.
One ordered list with a next item, an architecture that flows one way, and a fixed slot each month to decide the rest.
From our work
Predictive maintenance for LED boards installed worldwide
The interesting part was not the code. It was deciding that the devices should report in at all, what they should send, and where it should land — architecture decisions made before anyone wrote a line, on hardware already installed at customers around the world.
Your CTO on call, in Munich
We are at home in Munich (Baaderstraße 40, Glockenbachviertel) and sit down with you in person where that is the faster way. The advice comes from people who still build software every week — which is the difference between a slide deck and a decision you can act on.

How we get started
Free intro call
30 minutes on the decision that is currently stuck. No preparation, no documents — just the question.
Review & priorities
We look at what exists and hand you a short, ordered list of what will hurt as you grow — not a report nobody reads.
A fixed slot each month
From there it runs as an arrangement: a recurring slot for decisions, reachable in between, more around a launch and less afterwards.
