We develop your bespoke business platforms, workflows, ERP, CRM, SaaS, internal tools and mapping solutions. Our robust and intelligent architectures connect your systems and integrate AI where needed to automate, analyse and sustainably improve your processes.
Three profiles, one same promise: custom software that lasts, without breaking your budget.
Startups and product creators
You have an idea to validate and need to move fast. We start with a lightweight prototype, owned as such, to test the market within weeks. If it takes off, we know how to industrialize without starting over: we've done it many times before.
SMEs and nonprofits going digital
Your teams juggle between Excel, emails and software that don't talk to each other. You lose time and data. We centralize your operations in a single tool, designed for your business or your mission.
Growing companies ready to scale
Your tool still holds, but it's cracking. You need robustness, automation, and a team that keeps up. We start with a clear diagnosis: we keep what can be kept, we rewrite what must be rewritten.
Is your organisation still running on outdated tools?
The hidden cost: operational slowdowns, administrative burden, human errors and fragmented data.
Excel as the main tool
Manual management of critical data across scattered files
Generic tools that don't fit
Standard software that no longer fits your business processes
Disconnected Platform
Fragmented data across disconnected systems
Time-consuming manual processes
Repetitive tasks that needlessly tie up your teams
Say goodbye to scattered Excel files and data entry errors. Centralise all your operational activity in a single, secure interface built for your teams' productivity.

Competitive thanks to our business building blocks
15 years of projects have forged our building blocks: authentication, ERP, CRM, mapping, integrations. Every project builds on this proven foundation. The result: up to 20% cheaper than a from-scratch development, at higher quality.
Pragmatic, impact-driven
No over-engineering, no bloated systems. We aim for maximum impact with minimum motion. Our rule: if a feature doesn't change anything for your users or doesn't create value for your business, we don't build it.
Long-term partners
We don't deliver and disappear. Our client relationships are measured in years, not months. Some of our earliest clients have trusted us for over 10 years. That's no coincidence.

KERN-IT is a human-sized team, based in Brussels and active in Belgium, France, the Netherlands and Switzerland. We choose our clients, we invest in them, and we grow with them. A stable team that stays with you from first prototype to growth.

A free 30-minute audit to frame your idea and your next steps.
We look at your idea, your market and your stack. You walk away with a concrete recommendation, whether we work together or not.
We believe in long-lasting relationships built on trust, transparency, and a deep understanding of your challenges. Our commitment goes beyond delivery: we stay by your side over time, helping you make the right choices and move forward with confidence.

We apply a genuine software engineering approach to build the digital core of your organisation: business platforms, bespoke ERP and CRM systems, internal tools and mapping solutions. We use a modern stack (Python, React, PostgreSQL, AI, IoT, etc.) and simple, robust and scalable architectures rather than passing fads.
Our R&D activities and experience with complex projects enable us to make the right technical choices at the right time, taking into account your actual constraints. From business analysis to design, development to deployment and maintenance, our team supports you every step of the way to align your digital tools with your operations and long-term objectives.

Looking for a custom ERP, SaaS, business tool or tailor-made internal platform?
Let’s discuss your project and build together the solution that will transform your operations.
Our projects start at €8,000 ex. VAT for a prototype.
The price depends on the scope:
Prototype: from €8,000
MVP: from €15,000
Full business tool (ERP, CRM, platform): from €30,000
Rebuild of an existing system: based on audit
Our business building blocks let us be on average 20% cheaper than a from-scratch development, at higher quality. We always start with a free conversation to frame the actual budget.
No.
KERN-IT is a human-sized team, based in Brussels and active across several European countries. We choose our clients to invest deeply in every project.
A 2-person startup, a 15-employee SME or a 200-person organization: what matters is a real need and an open dialogue. No one is ever too small for us to care.
Not at all. It's actually the case for most of our SME clients.
Our job is to bridge your business goals and the technical reality. You decide on the business side, we handle everything else: design, development, hosting, security, updates.
You stay in control of what matters: what the tool does, for whom, with what impact.
The goal is always to have something usable quickly.
Some benchmarks:
Prototype or MVP: 2 to 6 weeks
First version of a business tool: 2 to 4 months
Full rebuild of an existing system: 4 to 9 months
We ship in short iterations. You see something tangible every 2 to 3 weeks, you validate, and we move on. No black-box tunnel.
Yes, anywhere in the world.
We regularly work with clients in France, the Netherlands, Switzerland, and beyond European borders. Distance is not a barrier: what matters is the quality of the dialogue, short validation cycles, and suitable collaboration tools.
We work in French and English.
When:
Excel files keep multiplying
Information travels through email
Duplicate data entry becomes frequent
Errors are on the rise
Coordination becomes complex
If your information system relies on makeshift solutions, it becomes a brake on growth. That is when structuring becomes strategic.
The digital core is the central system that connects your ERP, CRM, SaaS tools and internal processes.
It:
Structures and cleanses data
Automates key processes
Routes information to the right place
Reduces reliance on informal processes
Without a clear architecture, growth creates complexity. With a structured digital core, it becomes manageable.
Yes. We start with an audit of the existing system to see what can be kept, improved, or taken over.
Three possible scenarios depending on the diagnosis:
Targeted improvements on the existing tool
Takeover and modernization of part of it
Full rebuild if the existing system no longer holds
We always recommend first what can be kept or improved. A full rebuild is only a last resort.
Primarily:
Growing SMEs
Multi-team or multi-site organisations
Companies with complex processes
Organisations looking to scale without multiplying tools
Custom software becomes relevant when complexity outgrows standard off-the-shelf solutions.
Yes.
We regularly build:
Proof of Concepts
Functional MVPs
Testable prototypes
This allows you to validate a model, test a market or build an initial version before committing to a larger investment.
We integrate AI when it saves time or removes friction, not just for show.
A few concrete examples:
Agents that automate repetitive tasks
Bulk document analysis
Automatic data classification
Writing and research assistance
If AI doesn't bring anything measurable to your business, we tell you. No AI just to tick a marketing box.
Yes, and it's something we're proud of.
Some of our earliest clients have trusted us for over 10 years. We don't deliver and disappear: we stick around with maintenance, evolutions, fixes, and a direct point of contact whenever you need one.
KERN-IT has been around since 2010. This is what we do, and we plan to keep doing it for a long time.
