About · Our experience
Numezis Advisory & Engineering exists for the point where enthusiasm meets enterprise reality: workflows, systems, permissions, risk, adoption and value.
Why Numezis
The gap between an AI recommendation and a dependable system is full of consequential decisions. When advisors leave before architecture and engineers enter after strategy, those decisions are fragmented — and accountability is lost between teams.
Numezis brings senior advisory, product, engineering and security together from the start. The team that frames the opportunity understands the production constraints. The team that builds the system understands the business outcome and risk acceptance behind it.
Our ambition is deliberately focused: help Swiss organizations make fewer, better AI decisions and carry the right ones all the way to secure, measurable execution.
Numezis ecosystem
Numezis Advisory & Engineering combines client delivery with the products built across the wider Numezis group — software, physical AI infrastructure and multi-agent systems. Each has a clear role; together they form a product-led technology company grounded in governed execution.
The advisory and delivery practice
We help enterprises decide what to build, govern the risk, engineer the right system across vendors and architectures, and measure its value.
Work with the practiceThe concrete software product
An autonomous business agent for Swiss SMEs that handles documents, invoices, payments, follow-ups and approvals under governed rules.
Explore the Numezis productThe physical AI infrastructure service
Private AI installed, operated and warranted inside client premises: GPU-equipped machines assembled and tested in Switzerland, with zero data leaving the building.
Explore Numezis AI InfrastructureThe agent and multi-agent work system
A complete product that plans, orchestrates and delivers complex business tasks — built by Numezis and already used by SMEs.
Explore KletronOur products prove that our engineering discipline operates under real production constraints. They are not the default answer to every advisory engagement: recommendations remain architecture-first, vendor-flexible and led by the client’s requirements.
What differentiates the work
Experience from the market’s early formation, when organizations were learning what the technology could — and could not — reliably do.
One senior team owns the connection from executive thesis and governance through architecture and production.
Controls, data boundaries and evidence are designed with the system, never applied as a late-stage review.
We select tools against requirements and preserve reversibility where it creates strategic value.
Named people, visible effort, rolling priorities and monthly budget governance in time & materials.

Romain Magnin has been working in applied AI for Swiss organizations since the market’s early formation, when few had settled models for governance, security or measurable value.
That operating experience shaped a clear conviction: AI creates durable value only when business design, software engineering, governance and security are treated as one system. It led him to build the Numezis product family — including Numezis AI Infrastructure, which installs and operates private AI directly inside client premises — and Kletron, its multi-agent work system.
At Numezis Advisory & Engineering, Romain leads client strategy, architecture decisions and senior delivery governance.
