The CTO
A senior partner in your decisions.
Architecture, hiring, what to build next, what not to build. Wojciech is in the room when those calls get made.
A fractional CTO. With the build team attached.
Most fractional CTOs hand you a roadmap and a hiring problem. This engagement embeds CTO-level judgment in your company, with the senior team that ships what gets decided. Monthly retainer plus scope, long-running by default. Closer to a co-founder than a vendor.
What a founding
partnership looks like.
The default agency model assumes a known scope and a clean handoff.
Domain-expert founders rarely have either.
The team
A real in-house build team.
Three more senior developers behind the CTO, working to the same standards. Real capacity to ship two workstreams in parallel.
The pricing
Monthly retainer plus scope.
You're paying fees for ongoing technical judgment, and the cap table stays yours. Scope shifts as you learn. The model is built for that.
The horizon
Long-running, by default.
We stay long enough to ship, then long enough to maintain what we shipped. Most engagements run multiple years. And when you're ready to hire in-house, we help you make those hires and hand over a codebase they'll thank you for. That's the point of yet.
Different domains, same engagement shape.
Campaign Finance
Political finance, regulated industry
A non-technical political-finance operator brought us a decade of regulated-industry expertise and a problem nobody had solved well. We took it on as our own. Wojciech is a co-founder. Our deepest engagement to date.
Architecture from scratch. Co-founder-grade equity stake. Long-running engagement, still active.

Systellar Space
Satellite data platform
Two founders with deep space-domain expertise and, when we met, very little software between them. Mid-build and stuck on the architecture for a satellite data platform. We advised, then we built it. In production since 2026.
Started as advisory. Converted to a partnership engagement once the technical answer was clear. Founders kept ownership. We kept technical judgment.

How we work
AI as leverage for
senior engineering.
It writes a good deal of our code. What it has never done is decide what to build, or notice that the thing being built was the wrong thing. The structural argument for why that holds is on the stack page.
Specification-driven.
We write the design before we write the code, AI or otherwise. The spec is what we review, argue about, and change. Implementation is downstream of judgment.
Aggressive review.
Every change is read by a senior engineer before it ships. AI implementation doesn't get a free pass. It raises the bar on review.
End-to-end type safety.
TanStack Start + Supabase generates types from your database to the frontend. AI hallucinations break the build before they reach production.
Built to be inherited.
When the engagement ends, and it might not, you're left with code another senior team can read. Maintenance is a design constraint we hold from the first commit.
Built for domain-expert founders.
- You’ve spent years in some specific field: a working musician, a political operative, a satellite engineer, a clinician, a sector veteran. Domain depth is the thing you’re bringing.
- You’ve seen a problem only you can describe properly, and you can’t find a textbook software answer to it.
- You can’t (yet) hire a full-time CTO with a build team behind them, but the work still needs senior engineering.
- You’ve been burned, or know someone who has, by the spec-and-deliver agency model. You’re looking for a technical peer to make the calls with you.
