Crux Digits is a Netherlands-based custom software development company that builds AI-first products — web apps, AI agents, ML models and integrations — from a fixed-price audit to production. Based in the Utrecht region, a small senior team, fixed prices, and the code and IP are yours.
Crux Digits is a boutique AI consultancy and development partner for Dutch SMEs (MKB), based in Nieuwegein in the Utrecht region. Bilingual (EN/NL), with transparent fixed pricing — a €2,500 AI audit, a €20,000 proof of concept and a production build from €50,000 — delivered by a named expert (founder Tom Joseph), with 13 real case studies, EU AI Act- and GDPR-ready. A focused alternative to the large enterprise consultancies.
We build custom software around your process and data, with AI at the core — not a generic tool you have to bend your business around:
Full web applications, portals and platforms — from internal tools to customer-facing products, with AI built in where it adds value.
Agents that take actions across your systems: pulling data, deciding within rules, routing tasks and escalating exceptions.
Prediction, classification and anomaly detection, trained on your own data and deployed inside your stack.
Grounded assistants and RAG systems built on your own knowledge — with source citation and guardrails.
Visual inspection, detection and quality control — on the edge or in the cloud.
Pipelines, warehouses and connectors to ERP, CRM and APIs — the foundation every product runs on.
We are honest about who we are: Crux Digits is not a generic full-stack body shop that takes on every brief. We are a senior team that builds custom software with AI, data, machine learning, LLMs and computer vision at the core — plus the web, app, data and integration work a real product needs. If you want a team that actually takes an AI idea to production rather than only advising on it, you are in the right place.
What separates us from a classic software agency is the starting point. A generic agency begins with a specification and builds what is on paper. We begin with your data and your process, pick the use case that moves the needle together, and build a working system that learns and improves. Strategy and engineering sit in one team — no handover to another vendor, no knowledge lost in translation. Want the broader AI angle? See our AI development agency in the Netherlands.

We work in three fixed steps with transparent pricing — and you own all the code we deliver:
A prioritised opportunity list with ROI per use case and a clear build plan.
Working software on your own data, in weeks — not months.
A full system, integrated, in production and maintained.
Inside every step we work in one- to two-week cycles, so you see something working every week rather than a status report:
We pin down the users, the workflows and what success looks like, in your terms.
Architecture and UX are settled before a line of code is written. Integrations with your ERP, CRM or WMS are named here.
Short cycles, visible every week. Tests, audit logging and access control are part of the build, not the handover.
Go-live with a runbook and a handover session. Then maintenance and new features, or your own team takes it on.
An in-house team pays off once software work is continuous: a product that changes every week, a backlog that never empties. For a bounded system, a first version or an integration that has to be right once, a fixed-price agency is faster and costs less per delivered outcome, and you keep the code. The middle path works too: we build the first version and hand it to your developers with documentation and a runbook. More on the choice: agency versus in-house team, the trade-off.
Custom software development in the Netherlands typically bills €80–€150 per hour, and projects vary widely: a small custom build €25,000–€75,000, a mid-sized platform €75,000–€200,000, and complex systems above that. Hourly engagements are open-ended — the final bill is not fixed up front.
Crux Digits quotes fixed steps instead: €2,500 audit / €20,000 proof of concept / from €50,000 production (excl. VAT). The audit always includes a projected ROI, so you know the return before you commit. See the full 2026 price breakdown and our pricing.

It depends on what you are building. Large programmes suit established IT firms, consumer apps suit product studios, and tightly scoped work suits a boutique. Offshore is less expensive per hour but costlier in coordination. Choose on the shape of your project, not agency size.
Offshore is less expensive per hour; Dutch is less expensive per delivered outcome. On a tightly specified project offshore often wins on price. On work where scope sharpens during the build — which is nearly always true of AI — you pay the difference back in coordination.
