The AI Operating System

The governance and audit layer for AI workflows in regulated industries

PHÖNIX reviews, builds and evidences the use of AI in your company. Not in a binder, not in a policy document, but where your people actually work with AI: in the workflow.

Tools PHÖNIX layer Workflow

AI governance you can prove.

At PHÖNIX, data sovereignty is not a promise but an architectural decision. Where the case requires it, models run locally on your premises. Where cloud services are involved, the data paths are described, limited and logged. You are not asked to sign a leap of faith. You receive evidence you can verify: which data flows where, who has access, what is stored.

One example: a language model that summarises contracts can run on a machine inside your own network. The contracts never leave the building. And exactly that can be demonstrated instead of merely promised.

Three services, one principle: verifiable instead of asserted.

How an engagement runs.

  1. Initial consultation

    You describe the situation, we define the scope. Free of charge.

  2. Assessment

    A non-disclosure agreement (NDA) precedes any look into your operations. We then map where and how AI works in your company.

  3. Findings

    You receive the results with priorities and discuss them with us in a meeting. The timeframe from start to findings is stated in the proposal before you commission anything.

  4. Implementation

    On request, we rework the items from the findings together with you. You decide scope and order.

What PHÖNIX is not.

Frequently asked questions.

Does the EU AI Act apply to our company?

Very likely yes, to varying degrees. The transparency obligations under Art. 50 of the AI Act (Regulation (EU) 2024/1689) have applied since 2 August 2026; the obligations for high-risk systems follow on 2 December 2027 (Digital Omnibus, agreement of 6 May 2026). Which role your company holds and what follows from it becomes clear by looking at your actual AI use. An overview of terms and deadlines is on our knowledge page.

Does our data stay in-house?

That is an architecture question, and it is answered before the start, not afterwards. Depending on the case, models run locally on your premises, or cloud paths are described, limited and logged. You see in advance which data flows where. A non-disclosure agreement precedes any look into your documents.

How do we start?

With an email. You receive a proposed date for an initial consultation, followed by the non-disclosure agreement and the assessment. You take on no obligation before scope and approach are agreed in writing.
