AI agents for technical professions.
Pathesy designs, deploys and operates agents that read your technical files, apply your standards and produce traceable deliverables. As SaaS, or built in your own environment.

A useful agent is a model plus everything else.
In technical professions, generic AI rarely fails for lack of intelligence. It fails for lack of context, tools and control. We build everything around the model.
What technical professions require
Five layers. Three control planes.
The same foundation runs our products and the agents we build for our clients. Select a layer or a control plane to see what it does.
Control planes, applied to every layer
Agents you can audit.
An agent that produces a technical deliverable must be accountable. These principles are enforced by the platform, not left to each agent.
Humans approve
Changes arrive as a reviewable plan. Nothing is applied without your approval.
Least privilege
An agent only accesses the tools and data declared in its profile, project by project.
Evaluated before production
Test sets built from real project files. A new version only replaces the old one once it has been evaluated.
Traces and costs
Every run is traced step by step. Usage is tracked per agent and per project.
Model-agnostic
The gateway routes each task to the right model. Switching providers doesn't mean rewriting the agent.

Subscription, visible usage credits, continuous updates. Connect your sources and your teams use it from day one.

Agents come into your production software. Create views, compose sheets, fill in parameters, place families: you ask, and the agent does it in the model.
- Every action can be undone with a single Ctrl+Z.
- You review before saving.

Frequently asked questions
Partner
What is an AI agent?
A specialized assistant that acts autonomously. Unlike a chat assistant, an agent acts: it analyzes, decides and executes, citing its sources at every step.
What is Pathesy?
A platform to build, deploy and oversee AI agents for technical professions. It is available as SaaS, with a first product for AEC, or deployed in your environment with Pathesy Build.
How do I use Pathesy?
You create a project, connect your document sources, then choose an agent suited to your use case and give it your instructions. The agent produces the deliverable; you review and approve it.
Where is my data hosted?
In France, in the European Union. Each project has its own index, and an agent only accesses the data declared in its profile.
My field isn't covered yet. What now?
That's what Pathesy Build is for. We scope your use case, design the agentic architecture and build your agents on the foundation already in production, fixed-price or time-and-materials.
Let's talk about your agents.
