Product engineering
End-to-end design and development of web, mobile and backend systems. Architecture, delivery and the unglamorous infrastructure that keeps it all standing once real users arrive.

We build software
that thinks for itself.
Craftsline designs, engineers and operates modern software products and agentic AI systems — from the first prototype to the version that runs your business every day.
Weeks, not quartersWorking software every sprint
Cost-aware by designEvery AI call measured and capped
Built in the EUGDPR-minded from day one
Services
Engineering, intelligence, and the parts in between.
We work as the product and engineering team for companies that need senior output without the overhead of an agency.
Agentic AI systems
Autonomous agents, retrieval pipelines and language-model workflows wired into real business processes — with structured outputs, guardrails and a cost ledger on every call.
Mobile applications
Cross-platform iOS and Android apps built for the store and for the long run: native performance, offline behaviour, subscriptions, analytics and release pipelines included.
Cloud & platform
Pragmatic infrastructure: containers, CI/CD, observability and security hardening sized to the business — not an over-engineered platform that costs more than the product earns.
Approach
A short path from idea to something live.
Three phases, no theatre. You see working software early and keep seeing it every week.
01 — DEFINE
Start at the outcome
We begin with the business result you need and work backwards to the smallest system that delivers it. Scope is a decision, not a surprise.
02 — BUILD
Ship in short cycles
Vertical slices over big-bang releases. Every iteration ends in something you can open, use and judge for yourself.
03 — OPERATE
Stay after launch
Monitoring, cost control, security review and iteration. Software is a living thing — we treat the running system as part of the work.
Company
An independent studio, registered in the Netherlands.
Craftsline is a Dutch-registered software company building digital products and applied AI systems for founders, small teams and established businesses across Europe.
We keep the team deliberately small and senior. That means the people who scope your project are the people who write the code, and decisions about architecture, cost and security are made by someone who will still be there when the system is in production.
We work in English and Dutch, remotely across the EU, on both fixed-scope projects and ongoing engineering partnerships.
