ZERYON SYSTEMS Talk to us
Enterprise AI development · AI systems, automation & native Apple apps

We build AI systems companies can actually control.

From idea to governed execution — built individually: AI agents, workflow automation and knowledge systems. This includes native Apple applications for macOS, iOS and iPadOS, wherever full data ownership and premium UX matter.

Nearly 90 % of companies see less return from AI than their spend implies — not because of the technology, but because no one governs, documents and proves the decision. That is exactly what we build in. Source: Roland Berger, “The AI Value Gap”, 2025 (n = 203).

We run what we build: AXYON and ZERYON Control Studio are licensed products we sell, GARION, KAIRON, AIRPROOF, ORTYON and Course Studio run in our own operation.

The control we describe above is something we sell.

Two systems we developed ourselves, both sold as a perpetual licence, both operated inside the customer's own house. AXYON decides at runtime about the single action of an AI agent. ZERYON Control Studio is where the rules for that are designed and tested.

Execution Control Layer

AXYON

“May this action run?”

AXYON sits between the AI agents and a company's systems. Every action an agent wants to initiate is checked against fixed rules first. Anything that requires approval goes to a human, under four-eyes control. What was ordered, approved and initiated then sits in a chained, tamper-evident log — together with the target system's response, and including the refusals.

Two form factors on the same core: a container appliance for production and a native macOS app for the workplace. The governance is identical in both.

Governance Design & Control

ZERYON Control Studio

Design first, arm later.

Control Studio is the stage before that. Agents, workflows and policies are designed and rehearsed there — with full governance but without real side effects. Every proposed action is checked deterministically, approved under four-eyes control where required, and recorded tamper-evidently. What proves workable there goes into production afterwards.

Runs locally on the Mac. Within twelve months the licence amount is credited in full against an AXYON Appliance licence.

The gap

AI demos are easy. AI systems are not.

A chatbot can answer. A business system must execute, document, escalate, recover and survive failure. Many build AI demos. Few build AI systems that hold up inside the business. The market confirms it: 63 % of companies measure their AI success through one-off analyses or gut feeling rather than continuous evidence — exactly the gap a system with roles, logging, fallback and audit closes.

VS
What most build

A chatbot

"Sure — here's a draft answer for you."

Answers in isolation. No data lineage, no roles, no logging, no fallback. Impressive in a demo — fragile in production.

Services

Three services, one systems standard.

Automate, build, advise — thought through as one controllable system, not separate parts.

AI Automation

AI automation & workflow design

End-to-end workflows: input → AI → control → output — with approvals, logging and fallback. Automation that actually runs in production.

See the systems →
Software Engineering

Native apps & AI engineering

Our native Apple pillar: macOS/iOS/iPadOS apps, AI, plugin and application development — with full code & IP ownership, no vendor lock-in.

Business Consulting

Strategic AI & process consulting

Use-case assessment, ROI, process optimisation, governance & EU AI Act — from 30+ years in IT and business. AI decisions you can prove.

How we work

Three ways to start with ZERYON Systems.

The services above are what we deliver. Here is how you get started — whether you want to see a system, get strategic advice, or try it out first.

What we build

Systems

AI apps, workflow automation, knowledge intelligence, governance by design, private/local AI and controllable agents — as executable systems, not slides.

Trust & references

AI systems that actually hold up.

We don't claim it — we run it. AXYON and ZERYON Control Studio are licensed products we sell; GARION, KAIRON, AIRPROOF, Course Studio and ORTYON show our native Apple pillar in production. We apply the same architecture — roles, evidence, fallback, audit — to AI automation and workflow systems for clients, many of them web- or server-based and under NDA.

Execution control layer

AXYON

Checks every action an AI agent proposes against fixed rules before execution, obtains human approval where required, and keeps a chained log of what was ordered, approved and initiated — including the refusals.

FAQ

Frequently asked.

What does ZERYON Systems do?
We're an enterprise AI development house building controllable AI systems for companies: AI agents, workflow automation, knowledge intelligence and governance by design. We also build native Apple applications for macOS, iOS and iPadOS — a third pillar alongside automation and consulting. On your infrastructure, GDPR-compliant.
How are you different from a classic AI agency?
We build executable, controllable systems with human review, logging, fallback and audit — not demos and not isolated chatbots.
What is AXYON?
AXYON is our execution control layer between AI agents and a company's systems: every action is checked against fixed rules before execution, actions requiring approval go to a human, and what was ordered, approved and initiated then sits in a chained log — including the refusals. Perpetual licence, operated in your own house, as a container appliance or a native macOS app. Go to the AXYON page.
How do AXYON, Control Studio and GARION differ?
GARION assesses organisational readiness for the EU AI Act and NIS2. ZERYON Control Studio designs agents, workflows and policies and rehearses them without real side effects. AXYON decides at runtime about the single action.
Who owns the code and data?
You. Full code and IP ownership, no vendor lock-in. Optionally fully self-hosted AI on your hardware.
Is everything GDPR-compliant?
Yes. EU hosting (netcup) or your own infrastructure — up to fully self-hosted AI with your own LLMs.
How quickly are there first results?
Usually 4–12 weeks depending on complexity, starting with a free discovery call.
What does an AI project cost?
Flexible model: project-based or a monthly retainer. We clarify details in the free discovery call.
How do you measure whether the AI pays off?
Measurability is part of the system, not an afterthought: defined KPIs, logging and an audit log keep the value provable over time — instead of a one-off estimate after launch. This is exactly where 63 % of companies fail, according to Roland Berger (2025).
