Belgian software development company: we build the digital core of your organisation

KERN-IT is a Belgian software development company based in Brussels, active since 2012 in Belgium, France, the Netherlands and Switzerland.

Nous concevons des plateformes métier, des ERP et CRM sur mesure, des SaaS et des agents IA, avec une équipe à taille humaine qui accompagne chaque client dans la durée. Nos projets démarrent à 5 000 € HTVA et nos briques métier nous rendent en moyenne 20 % moins chers qu'un développement from scratch.

When choosing a software development company, look at three things: architecture before code, verifiable references in your sector, and presence after delivery. Those are our three commitments.

Our projects start at €5,000 ex. VAT for a prototype.

The price depends on the scope:

• Prototype (even vibecoded): from €5,000
• 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: 2 to 6 weeks
• MVP: 2 to 3 months
• 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.

You can start small: turning a single Excel file into an application starts from €5,000 excl. VAT for a very simple file, €20,000 on average, and the platform then extends to other departments.

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.

A.M.A, our internal agent, has been automating our own processes since 2018: first a chatbot, now an autonomous agent orchestrating complete workflows.

Each of our eleven business platforms ships with an operational AI assistant, including Bob for invoicing (GestAccount) and Sherpa for training (KernAcademy). For our clients, we deploy LLM agents, RAG and intelligent automation.

AI is only integrated where it brings a measurable gain to your teams.

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 2012. This is our craft and we intend to keep at it for a long time.
