Independent technology studio · Netherlands
Practical tools, built in the Netherlands.
Boomarche designs and ships small, careful products — AI tools for European teams with EU data residency by default, plus a quiet aerospace R&D venture. Built first for ourselves, then shaped into something other people can use.
Products
A small portfolio. Each one solves a specific problem we hit in our own work.
Some are open. Some are private beta. Some are still being shaped. None are general-purpose.

How we work
Four principles that shape every product we ship.
- 01
EU data residency
Hosted on Azure in EU regions. Azure OpenAI for LLM workloads — your prompts and data stay in Europe.
- 02
Built first, sold second
Every product solves a problem we have ourselves. We ship to ourselves before we ship to anyone else.
- 03
B2B-ready when it matters
Single sign-on, audit logs, and procurement paperwork available on request for enterprise customers.
- 04
Small and accountable
Boomarche is a Dutch ZZP. You talk to the person who builds the product. No layers, no handoffs.
