A boutique practice for a custodial problem.

What we are

ANULUM is a founder-led engineering practice based in Marbach SG, Switzerland. We design confidential AI systems end to end: the deployment architecture, the hardware sourcing through warrantied Swiss channels, the document pipeline, the retrieval and citation layer, the governance evidence, and the ongoing operation.

We are deliberately small. Engagements are taken one at a time, led by the same people from the first conversation to managed operation. Clients are never named; reference conversations happen only with explicit consent.

What we are not

• Not a cloud platform — your archive does not live on our systems.
• Not a hardware reseller — hardware is procured for your project, under your warranty, with our engineering.
• Not a legal, financial, or medical adviser — our systems support your professionals; they do not replace their judgement.

How we work

Every engagement starts with the confidential architecture review: a paid, fixed-scope step that ends in a decision document — including the honest answer when a private AI system is not justified. Production systems follow only on your explicit decision, are evaluated on your material before reliance, and run under a defined support agreement.

The engineering culture behind ANULUM comes from research computing: measured claims, reproducible results, and the habit of writing down what was actually tested. The broader research work of the ANULUM ecosystem lives at anulum.li; this site is dedicated exclusively to the private AI infrastructure practice.
