Custom AI Development Company in the Netherlands

GreyScript AI is a custom AI development company. We build AI agents, AI-native web and mobile apps, MCP tooling, retrieval, and automation in the Netherlands, for Dutch and international businesses that run much of their work in English.

Buyers in Amsterdam, Rotterdam, Utrecht, and Eindhoven often look for an AI development agency in the Netherlands that can ship into production under GDPR and the EU AI Act. We treat those as design constraints. We do not certify compliance. Engagements start with a 30-minute scoping call, and we reply within one business day.

Custom AI and software we build

We are a custom software and AI development company, building in the Netherlands. Each of the fourteen services is scoped on its own: web and mobile apps, agents, MCP tooling, integration, automation, and more. A strategy engagement does not commit you to a build.

AI strategy and readinessScore the ideas before any engineering starts. Usually 2 to 4 weeks. AI-native web and SaaSA new product where AI is the core, not a feature added later. AI-native mobile appsiOS and Android, with on-device inference where latency or privacy needs it. AI agents and copilotsCopilots, chat products, and multi-agent workflows, with a person on the actions that matter. MCP and agent toolingSafe, structured access to your database, internal APIs, and other tools. Custom modelsFine-tuning when a general-purpose model is not accurate enough. AI integrationAI added to a product you already ship, inside the current codebase. MLOpsDeploy, watch latency and drift, and keep token cost under control. Vision and languageDocuments, images, and text classification. Workflow automationThe internal process that actually wastes time, then the tools around it. Data preparationPipelines, cleaning, and schemas so retrieval and fine-tuning are reliable. Voice AIPhone lines and in-app voice, with a handoff to a person. Chatbots and website copilotsPre-sales and support, grounded on a curated knowledge base. AI governance and securityPrompt injection, tool misuse, and data exposure, before or after launch.

Examples from our work

These are illustrative examples. The company in each one is anonymized, and the figures are not a documented client result.

Working with us

Delivery is English-first: specs, demos, and documentation. That fits many international teams in the Netherlands. Customer-facing AI can be English, Dutch, or both when your users need it.

We do not publish sample prices in EUR or USD. After the scoping call you get a written proposal in the currency you agree.

Most engagements start with the AI strategy work: a short, fixed-scope pass over your use cases before any build begins. If a use case does not hold up under that review, we say so before any engineering starts.

From first call to production

1DiscoveryMap your data and the narrowest use case that can prove value.

2PrototypeA working system against real data, measured before build.

3PilotA limited slice of real usage, before we harden it.

4ProductionThe same engineers integrate, monitor, and ship.

5OperateWe stay on latency, cost, and model updates.

GDPR and the EU AI Act for Dutch products

Netherlands-based products sit under EU rules. We build with that in mind. We do not issue a compliance certificate.

GDPR (AVG). Data protection by design for personal data: purpose, minimization, access control, and a path for access, correction, and deletion.

EU AI Act. A design input for systems the Act covers. We inventory what the system does and where a person stays in the loop.

Security review for prompt injection, tool misuse, and data exposure, on the governance engagement or inside a build.
