software-architecture.aiFor solo founders, SMBs, and anyone building their product themselves with AI
Your Fractional CTO on call.
You make the big tech decisions without paying for a full-time CTO. I support you with the decision. And if you want, I build the finished system too.
Where it starts to wobble
You run your business, not your tech department. Yet the expensive technical decisions still land on your desk.
The quote you can't assess
An agency hands you a quote. It sounds plausible, costs a lot, and you have no one to tell you whether it's fair and complete.
The switch before the MVP
You're asked to commit to a stack before it's clear who maintains it later and whether it grows with you. One wrong turn, and the rebuild arrives in a year.
The risk that only shows up in two years
Security and scaling feel abstract today. Until the first big customer arrives and the system breaks exactly where no one looked.
The prototype that suddenly has to hold
You built your product yourself with AI: vibe coding, no-code, a prototype that turned real. In the demo, everything runs smoothly. Now the first real customers arrive, and questions surface that never mattered before: Does the architecture hold up? Where are the security gaps? What breaks at the next growth step?
You've proven you can build. Now it's about someone who looks at the tech with you and carries the hard decisions alongside you.
The packages
What should be built. What to leave out. Which switch catches up with you in two years.
That's what you hire me as an external CTO for: the judgment. You get it as a map to take with you, or as a finished system with it already inside.

The judgment
Fixed price, one-off and scoped
Then onward
Accompanied over time or built for you
You don't have to decide today. The usual first step is the walkthrough: 60 minutes, 99 €, credited toward anything further.
All prices net, plus VAT. Larger packages credit smaller ones. What fits you, we clarify in the walkthrough.
How it works
Walkthrough
We sort out where you stand in 60 minutes. You feel whether the chemistry fits, I see where it really pinches for you.
Architecture Compass
I work out the upcoming switches and give you a clear basis for deciding. From here you know what to do.
Build or accompany
You decide how it continues: I build the system at a fixed price, or I stay at your side as CTO on call while your team builds.
Among my clients
Two projects I'm allowed to show publicly. Others run under NDA and stay unnamed here.
Is this for you?
I don't work with everyone. That keeps the relationship honest.
This fits
- You're a solo founder or run an SMB up to about 20 people.
- You're making an expensive tech decision and don't want to make it alone.
- You want an answer, not a full-time salary for a CTO role.
- You'd rather have an honest verdict than a comfortable yes.
- You're building your product yourself with AI and want someone who looks at the tech with you and carries the decisions alongside you.
This doesn't fit
- Corporate IT, large ERP projects, banking core systems. Others do that better.
- You're looking for hands to execute what's already been decided.
- You want the cheapest solution, not the one that holds up.
- You're looking for full-time employment in disguise.
If you're standing here, I'll tell you early and point you elsewhere where I can.
