Radek Domański —
15+ years from developer to CTO across fintech, AI, and scale-ups. Here's how I think, who I work with, and what I actually do.
The pre-CTO gap
Seed done, first product live, a few engineers on the team. Technical decisions are starting to compound — architecture, hiring, delivery rhythm — but a full-time CTO hire isn't yet justified or hasn't landed.
That's the gap I fill. I come in as a part-time technical partner: owning the decisions a founder shouldn't be making alone, and building the systems the team needs to grow without me.
Good fit
- Seed-stage or post-Series A company
- No full-time CTO in seat yet
- A few engineers, initial stages of the product
- Decisions starting to back up
- Poland / EU (US possible)
Not a fit
- Company already has a strong CTO or VP Eng
- Pre-product (no tech to review yet)
Every engagement starts with a two-week Technical Diagnostic Sprint — fixed scope, fixed price, prioritised action plan as output. From there, most continue on an ongoing retainer shaped around what the company actually needs.
Full engagement detailsWhat I bring
15+ years from developer to tech lead to CTO — across telco, insurance, fintech, blockchain, and AI.
Systems thinker
The expensive mistakes are almost never technical failures — they're decisions to build the wrong thing, in the wrong order, for the wrong reasons. I optimise for direction, not just velocity.
Teaching instinct
I don't just make decisions — I transfer knowledge and build team capability. The test of a good engagement: the team is stronger when it ends than when it started.
Breadth as a moat
Not a stack specialist. The problems that set companies back 6–12 months rarely live in one technology — they live at the seams. 15+ years across industries and stacks is the point.
Stack & Tools
Technologies I've worked with across production systems — from AI-integrated products to regulated fintech backends.
