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.
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.

Hourly rates typically run €80–€150 and projects range from €25,000 for a small custom build to €200,000+ for a complete platform. Crux Digits works in fixed steps rather than open hourly rates: €2,500 audit, €20,000 proof of concept and from €50,000 production (excl. VAT), each with scope and price agreed before work starts.
Both, and we are honest about it. Crux Digits is an AI-first custom software development agency: we build real software — web, apps, data, integrations — with AI, machine learning and LLMs at the core. We are not a generic full-stack body shop; our strength is software where AI makes the difference.
Yes. We build AI software products from scratch — from a clickable MVP on your own data to a full system in production, integrated with your ERP, CRM and databases. One senior team carries it from strategy to launch.
Yes. Machine learning software development is a core part of what we do: prediction, classification, anomaly detection and computer vision, trained on your data and deployed inside your stack — with monitoring for accuracy and drift.
You do. All source code, trained models, pipelines and documentation are fully transferred to you at handover — no vendor lock-in, no ongoing licence fees.
Most clients start within 5 business days of agreeing scope. The process runs in three fixed steps — audit (€2,500), proof of concept (€20,000) and production (from €50,000) — and by the second call there is often already a clickable MVP.
Yes. Every build is checked against EU AI Act risk tiers and GDPR from the first line of code — compliance is built in, not bolted on.
