Vibe coding got you to v1. What gets you to v10?
You shipped a working product in weeks, not months. That part worked.
What happens next is the part nobody warns you about: features pile on features, the data model bends to fit each one, and the thing that let you move fast starts slowing you down. Not in a dramatic way. Quietly, over about six months.
Konstrukt is the engineering layer underneath. You keep shipping. We make sure it holds.
The three things that quietly break
AI-generated code doesn't have to be perfect everywhere. A few parts do:
- Your data model. Every feature after it inherits its shape. Wrong early, expensive forever.
- Auth and access. Decided feature by feature, never as a whole. This is where breaches live.
- API contracts. Services talking without a written contract, so every change becomes a gamble.
We call these the Expandable Core. On kickoff we write the Core Registry into your repo: every file, table and contract we treat as load-bearing. That list gets real review. Everything else moves fast.

Who we are
Deborah and Sébastien. We came out of Selego, where we built products for companies of every size. Selego still handles corporate-scale work. Konstrukt exists for founders.
We're in Tirana, a city built on 170,000 bunkers. We took the hint.
Questions founders ask
Is vibe-coded software safe to run in production?
It can be, as long as someone reviews the parts everything else depends on: the data model, auth and access, and API contracts. That is what Konstrukt does. Every PR gets an agent pass, then a senior engineer, within 24 business hours.
Do I need a CTO to scale an app I built with AI?
You need CTO-level judgment on architecture and review, not necessarily a full-time hire. Konstrukt Co-Build gives you that on a monthly retainer: we own architecture, security, CI/CD and incident response, and you keep building the product.
What does the Bunker Test include?
Read-only access to your repo, then a written Top Risks summary within 5 business days. It is free and yours to keep, whether or not you work with us afterwards.
How much does Konstrukt cost?
€4,500 a month, everything included, with no cap on PRs. Three months minimum, then month to month with 30 days notice.
Who owns the code?
You do. The code, the ADRs and the Core Registry stay in your repo. If you leave, we hand everything off and our access is revoked within 24 hours.
