Our Mission

You Own It. We build AI software that belongs to the people who use it. Not to us, not to a cloud provider, not to a model.

Our Mandate

We give organisations back control over their AI. Software they can own, understand, and leave at any time. Data sovereignty is the foundation, not an add-on.

Our Vision

A future where organisations use AI without making themselves dependent. We are the proof that powerful AI and full sovereignty are not a contradiction.

Our measure: has the organisation that uses our software gained more control, more clarity, and more time for what matters? If yes, we have done our job well.

Values

01

Ownership over Dependence

No lock-in. Full export, real deletion, deployable on your own hardware. Whoever can get in must be able to get out again.

02

Honesty over Hype

We promise what we deliver and deliver what we promise. No buzzwords, transparent costs, verifiable claims.

03

Determinism carries, AI shapes

A schema-validated foundation sets the rules. AI works as a tenant within them. Trust comes from traceability, not magic.

04

Data Protection is Respect

GDPR, data locality and audit trails as an attitude, not a chore. Respect for the people behind the data.

Our Brands

Two products, one principle: AI you own, understand, and control. Backed by a real company you can rely on for the long term.

hcai

How We Work Together

From first conversation to software you own and run yourself. Three clear steps, no lock-in along the way.

01

We Talk

We map your situation, goals, and constraints together. An honest assessment of whether we are a fit, with no obligation.

02

We Build on Your Terms

We deliver software that runs on your own hardware and follows the hcai principles: governance, traceability, and human oversight built in.

03

You Stay in Control

Full export, real deletion, no lock-in. Whoever can get in must be able to get out again. The software belongs to you, not to us.
