Something built from all of us, for all of us.

AI was trained on everything that makes us human. Klai brings it back as private AI for real work. European, open source, and built to last.

What we build

Private AI, for real work.

Klai is the AI infrastructure European organisations need to put real work into AI: client files, meeting notes, confidential documents. Hosted in Europe, open source, never trained on your data.

Two products, available now. Chat for private AI conversations with your own documents. Knowledge for your organisation's collective memory, searchable and private.

Infrastructure

100% EU-hosted

All data processing on European servers. No US data centers. No CLOUD Act exposure. No surprise acquisitions by foreign entities.

Ownership

Steward-owned, unsellable

Zero external investors. No exit strategy. The company belongs to the mission and cannot be sold. Written into law, not into our marketing copy.

Code

Fully open source

Every line auditable. Read it, fork it, self-host it. Your IT team knows exactly what runs where.

Founding principles

What we stand on.

Five beliefs came before the product. Four are written into our articles of association, which means they cannot be quietly revised by a board, a buyer, or a future management team.

Five principles

Five beliefs. Four written into law.

01

Something built from all of us should be for all of us.

AI was trained on shared human knowledge. It should serve everyone who built it.

02

Privacy is a precondition, not a feature.

Your data never leaves the EU. There is no mode to turn that off.

03

If you build on the commons, you owe to the commons.

Every line of Klai code is open source. A portion of revenue flows to upstream projects.

04

Critical infrastructure must be unsellable.

When banks, hospitals, and governments depend on a platform, it cannot be for sale.

05

You're not a customer. You are a patron of the commons.

Your money funds the infrastructure you use, not someone else's dividend.

The team

Decades of experience.

Mark founded Voys in 2006. Steven joined in 2012 as the company's jurist and strategist. Together with 140 colleagues and 33,000 business customers they grew this self-managed company, which became a steward-owned organisation in 2024. Jantine has spent the last four years shipping generative AI inside Dutch organisations, from Provincie Drenthe to Fotofabriek's StoryPrint.

Klai is what we bring to AI after two decades of working out how information, trust, and ownership should flow inside companies. The short version is in the bios below. The long version is the product.
