Short answer: AI specialists in the Netherlands typically charge €125 to €250 per hour, or €900 to €1,800 per day. A discovery or feasibility study usually costs €3,000 to €8,000, a first proof of concept €15,000 to €40,000, and a production solution for a small or mid-sized business roughly €50,000 to €150,000. The biggest cost factors are data quality, integration with your systems and how reliable the AI has to be.
Hiring an AI development company is different from hiring a regular software team. Part of the work is software engineering, and part is finding out whether the AI performs well enough on your data. This guide gives typical 2026 ranges for the Dutch market and explains how to budget for each phase. The figures are market ranges, not a quote.
Rates for AI developers in the Netherlands
| Type of provider | Typical rate | Best for |
|---|---|---|
| AI, data science or ML consultant | €125 – €250 per hour, or €900 – €1,800 per day | Strategy, model work and integration |
| Big-four consultancy | €2,000 – €3,000 per day | Large enterprise programmes |
| Specialised AI development company | Fixed price per phase or day rates in the consultant range | Building and running a working AI product |

AI project cost per phase
Discovery or feasibility study: €3,000 – €8,000
Define the use case, check your data, estimate value and choose the approach: an off-the-shelf model, retrieval-augmented generation (RAG) on your documents, or a custom model.Proof of concept or pilot: €15,000 – €40,000
A working version on real data that shows whether the AI is accurate and useful enough. This is the moment to stop or continue.Production build: roughly €50,000 – €150,000 for an SME
Integration with your systems, security, user interface, monitoring and testing. Enterprise-wide rollouts often reach six figures.Run and improve: monthly
Hosting or API usage, monitoring for accuracy, updates as your processes change, and occasional retraining.
What drives the cost of an AI project
- Data: clean, accessible data is the biggest time saver. Scattered or unlabelled data adds weeks.
- Type of AI: a chatbot or AI agent on top of an existing language model costs far less than training a custom computer-vision or prediction model.
- Integration: connecting the AI to your CRM, ERP, documents or apps is often the largest part of the work.
- Accuracy and risk: an internal assistant can tolerate some errors. AI that makes decisions about customers, money or health needs much more testing and human oversight.
- Privacy and regulation: GDPR applies to personal data, and the EU AI Act sets extra rules for some use cases. Check early whether yours is affected.
- Hosting choice: paying per API call is cheap to start, while hosting a model yourself can cost less at high volume or when data must stay in the EU.
Ongoing costs to budget for
- Model or API usage, which grows with the number of requests.
- Cloud hosting and vector databases for RAG solutions.
- Monitoring for accuracy and model drift.
- Updates when your processes, documents or products change.
- Security reviews and access control.
How to compare AI development companies
Quotes for the same idea can differ by a factor of three. Ask every supplier the same questions:
- Which AI solutions have you put into production, not only into a demo?
- How do you measure whether the AI is good enough, and what happens if it is not?
- Who owns the code, the prompts, the data pipelines and any trained models?
- Where is our data stored and processed, and is it used to train other models?
- What will it cost per month to run after launch?
- Can you also build the app, backend or integration around the AI?
Example: Clawleaf
ExtreemTek built Clawleaf, an AI agent platform that automates paperwork for healthcare teams. It shows the pattern most business AI projects follow: start with one time-consuming task, prove the AI handles it reliably, then connect it to the systems people already use. Our AI development services cover AI agents, LLM integration, RAG and computer vision, and our cloud and backend team runs them in production.
AI development cost FAQ
How much does an AI developer cost per hour in the Netherlands?
AI, data science and machine-learning consultants in the Netherlands typically charge €125 to €250 per hour, or €900 to €1,800 per day. Big-four consultancies often charge €2,000 to €3,000 per day.
How much does an AI proof of concept cost?
A first proof of concept or pilot on real data usually costs €15,000 to €40,000. A discovery or feasibility study before that costs around €3,000 to €8,000.
How much does a production AI solution cost?
For a small or mid-sized business, a production AI solution that is integrated, tested and monitored typically costs €50,000 to €150,000. Enterprise-wide rollouts often cost more.
Is it cheaper to use ChatGPT or another existing model than to build my own?
Usually yes. Building on an existing language model, for example with retrieval-augmented generation on your own documents, is far cheaper and faster than training a custom model. A custom model makes sense for specialised tasks such as computer vision on your own images.
What are the ongoing costs of an AI solution?
Model or API usage, cloud hosting, monitoring for accuracy and drift, updates when processes change, and occasional retraining. Ask for a monthly running-cost estimate before you start.
