AI you own · France / EU
Zenaiyo — AI you own: agents, private models and data.
We build AI systems for French and EU firms — and you keep the code, weights, prompts, data and logs.
For regulated mid-market teams in law, accounting, industry and other data-sensitive operations. Bilingual EN/FR, Paris-based, no vendor lock-in.
- You own the code, weights and data
- Human-in-the-loop by design
- EU / French-cloud deployment
- Bilingual EN / FR delivery
Your best people should not spend their week copying data between tools, chasing documents and answering the same questions. That work can be handled by governed AI agents — and you can own them.
What is Zenaiyo?
Zenaiyo is a Paris-based AI engineering partner. We find the workflows worth automating, deploy governed AI agents on your existing stack, operate them after launch, and measure the lift. Owned Intelligence is the outcome: the agents, private models and data we build are yours to keep.
Three ways to work with us
Start with the one that matches your next build. All three end the same way: you own the result.
AI agents & workflows
Production agents on your CRM, inbox, support and reporting stack — with logging, escalation paths and human handoffs you can audit.
Explore AI agents →OwnPrivate models & company AI Lab
Open-weight models, RAG or fine-tunes, evals and governance on your perimeter or a French cloud — with forward-deployed engineers embedded in your team.
Explore the AI Lab →DataRights-cleared AI data
Vet data providers, source licensed data and label datasets for AI — advisory scoping, not a consumer-profile marketplace.

Concrete ways to start. Each page says who the offer is for and how to book a call.
AI agents and workflows
Bookings, follow-up, billing and admin agents on the tools you already use.

The same delivery model, tuned to how the sector buys and which data must stay local.
- Accounting & auditSame AI budget many firms already spend—data stays in France.
- Law firmsClient and case data never go to generative AI unless pseudonymised.
- Industry & aero suppliersTrade secrets and export-control data stay on site.
- Government & public sectorAutomate citizen services and internal processes on infrastructure you control, not a foreign cloud API.
- Legal & finance auditAutomate document review, intake, and reporting without client data ever leaving your infrastructure.
- Logistics & supply chainFaster exceptions, cleaner data across partners.
- DentalA digital front desk that runs like your best coordinator—fast, consistent, and built for PHI boundaries.
- Real estateRespond faster to every lead without hiring another coordinator.
- Sport & fitnessLess admin, more floor time and member revenue.
- General use casesHigh-impact patterns that work across SaaS, services, and e-commerce.
- BTP — ConstructionSite communications, procurement, and compliance—automated on your stack.
- Irrigation & wateringScheduling, dispatch, and client reporting without extra back-office load.

From first workflow to owned system
One production lane first. Then the same governed pattern for the next one.
- 1
Diagnose
Map real workflows, bottlenecks, exceptions, owners and human boundaries.
- 2
Deploy
Connect your existing stack and launch one production lane.
- 3
Operate
Monitor exceptions, tune the workflow and maintain the system.
- 4
Prove
Measure time recovered, cycle time, response speed and data quality.
- 5
Expand
Apply the proven pattern to the next workflow.
How we work with you
No packages off a shelf. Every mission is scoped with you, so you only pay for what moves the needle.
Scoped to your mission
Scope and budget depend on your workflows, volumes, integrations and risk. After a free audit you get a clear plan and quote — no generic price list.

See sectors →Honest limits
Agents escalate to humans on exceptions. We tell you up front which workflows are not worth automating.
How it works →Frequently asked questions
Short, direct answers about how Zenaiyo works.
What does Zenaiyo do?
Zenaiyo is a Paris-based AI engineering partner. We diagnose workflows worth automating, deploy governed AI agents on your existing stack, operate them after launch and measure the business impact.
What does “AI you own” mean?
You keep the code, prompts, model weights, data and logs for everything we build. You can run it yourself, move it to another provider or hand it to your own team at any time.
Who is Zenaiyo for?
Regulated or data-sensitive mid-market firms in France and the EU — for example law, accounting and industry — that want more throughput on repetitive operations without proportional headcount.
What is a forward-deployed engineer (FDE)?
An AI engineer who works inside your team and stack rather than from a distance. They map real workflows, ship production systems and stay involved after launch.
Can you deploy on French or EU infrastructure?
Yes. We can deploy open-weight models and agents on your own perimeter or on a French or EU cloud when data must not leave a defined jurisdiction.
How do human oversight and safety work?
Agents log their actions, follow defined limits and escalate exceptions to a named person. Humans stay in the loop wherever a decision carries legal, financial or reputational risk.
How does an engagement start, and how is it priced?
It starts with a free automation audit and a short call. We then scope a pilot on one workflow. We do not sell fixed packages: pricing depends on the mission — volume, integrations and risk — and you get a clear quote after the audit.
Do you work in English and French?
Yes. Delivery, documentation and support are available in both English and French.
Find the work worth automating.
A free audit maps your highest-value workflows and tells you what to build first — and what to leave alone.
