Your idea deserves more than a fragile prototype
You have a digital product idea. Maybe an initial prototype generated with AI, maybe just a clear vision. At KERN-IT, we have been supporting startups and project founders for over 10 years: from idea validation to MVP launch, then from MVP to a product that scales.
The classic trap: coding too fast. A prototype without architecture quickly becomes technical debt that slows your growth. Our role: turn your ambition into a concrete product, with a controlled budget and a tech stack that holds up.
PoC, MVP, Product: which stage are you at?
PoC — Proof of Concept
Not sure it works? A PoC validates the technical feasibility of your idea in a few weeks. No interface, no frills: we prove the concept holds before investing further. Typical budget: €5,000 – €15,000.
MVP — Minimum Viable Product
Concept validated? The MVP is the first usable version of your product, with just enough features to test the market with real users. Deliverable in 2 to 4 months. Typical budget: €15,000 – €50,000.
Full product
Market validated your MVP? Time for a product that scales: robust architecture, optimised UX, API integrations, subscriptions, analytics. The goal: growth and retention. Typical budget: €50,000 – €200,000.
What we bring to startups
Technical CTO
No CTO? We play that role: stack selection, architecture, technical roadmap, future recruiting. You keep strategic control, we ensure technical execution.
Startup velocity
Short sprints, demos every 2 weeks, prioritisation by business value. We deliver fast because we know what can wait and what can't.
Proven stack
Python/Django, React, PostgreSQL, Tailwind CSS. Mature, documented technologies with a large developer pool. No exotic tech that locks you in.
Vibe engineering
Started with Cursor, Bolt or Lovable? We take over your AI prototype and turn it into a real product. AI accelerates, the engineer structures.

Our startup journey
1. Free discovery
A 30-min call to understand your idea, your market and your constraints. We honestly tell you where to start: PoC, MVP or something else.
2. Scoping & quote
Functional scope definition, stack selection, budget estimate. You know exactly what you'll get and for how much.
3. Agile development
Quick React prototype to validate UX, then MVP built on Python/PostgreSQL for robustness. 2-week sprints with demos. No 6-month development tunnel with no visibility.
4. Launch
Production deployment: domain, SSL, monitoring, backups. Your product is live and ready for its first users.
5. Growth & SaaS
Your MVP found its market? Time to scale: multi-tenant, subscriptions, public API, automated onboarding. From MVP to SaaS platform. We grow with you.

Frequently asked questions
A PoC (Proof of Concept) validates technical feasibility: can it work? An MVP (Minimum Viable Product) validates the market: do users want it? The PoC is internal, the MVP faces the market. We often start with a PoC when technical uncertainty is high, and go straight to MVP when the technology is proven.
That's the case for most of our startup clients. We act as an outsourced CTO: technology choices, architecture, roadmap, code review, technical recruiting. When your startup grows and hires a CTO, we ensure the handover.
Yes, that's exactly what we call vibe engineering. We audit your prototype for free, identify what's salvageable, and professionalise it: tests, architecture, security, deployment. Often cheaper than starting from scratch.
A functional MVP ranges between €15,000 and €50,000 depending on complexity. A validation PoC starts at €5,000. A complete product ready to scale costs between €50,000 and €200,000. We always adapt scope to your budget — a focused MVP is better than a half-finished product.
No-code (Bubble, Webflow, Airtable) works for validating a very simple idea. But as soon as you need business logic, integrations, performance or customisation, you hit the limits. We recommend no-code for some PoCs, but custom code for MVPs meant to scale.
We don't do fundraising consulting, but we help you build a demonstrable product that strengthens your case. A functional MVP with traction is the best argument in front of an investor. We also know the Brussels ecosystem and can point you to the right people.
