From a light diagnosis to a full build, every track is designed to deliver a concrete result — no long commitment, no surprises.
TRACK 1
The Audit
Map before you build
From €1,500
excl. VAT · 1 to 3 days
You know there's a topic, but not where to start. We set a clear diagnosis: what's feasible, at what cost, with what impact. You leave with an executable roadmap.
✓ 1 to 3-day audit, on-site or remote
✓ Analysis of your processes, tools and friction points
You have the vision, the budget, the need to do it all right. We take the project on end to end. One point of contact, a dedicated team, clear milestones.
We give you a real number after an initial conversation. Not a 1-to-10 range.
And then?
Two models for what comes next
Once the proof is made, two options open up. One favors flexibility, the other a controlled scope.
Agile Studio Recommended
≈ 1 dev day/week · 6-month renewable commitment
€2,500 excl. VAT/month
You prioritize, we deliver. No frozen spec, no amendment for every change. Just a continuous flow of improvements, driven by your real needs. Volume discounts: €4,800 for 2 days/week, and so on.
Fixed specification
Fixed price
Defined scope, firm quote, marked-out schedule. The classic format for projects whose contours are already clear.
Our advice: start with a proof of concept, then switch to the agile Studio. It's the formula that delivers the most value, the fastest, with the least risk.

No 3-month tunnel. You see the product move forward every 1 to 2 weeks. You test, you comment, you adjust. The best products come from this close collaboration.
Code delivered, documented, hosted on your side
Two possible setups:
›You host — we provide the specs and the docs to your team, which administers it in-house.
›Turnkey — we prepare the infrastructure (typically Scaleway), you get full ownership.
Either way, you own the code.
Why us
The right choice, for the right reasons
01
15 years in legal, not 15 months.
We speak your language. We understand your ethical constraints, your processes, your urgencies. No need to re-explain everything in every meeting.
02
Weeks, not quarters.
A prototype in production in 1 to 2 months. Demos every week. You see progress, you adjust in real time. No tunnel effect.
03
We build for ourselves too.
Nine Zevra products in production force us to code clean, fast and solid. You benefit from the same level of demand as our own teams.
04
Decisive advantage
Our R&D becomes yours.
This is our real advantage. MCP connectors, AI building blocks, authentication modules, integrations with legal databases: everything we've already built for others, you get.
You pay for what's specific to your project — not to reinvent what already exists at our place.
05
Legal AI, in production. Not in a demo.
17 legal MCP connectors are already running in production. We know what works, what hallucinates, what survives the real world. AI isn't a buzzword for us — it's our daily reality.

FAQ
Questions that come up
I don't have a specification.
No worries — it's often even better. We start from your problem, not a 50-page document no one reads. The audit (from €1,500 excl. VAT) is made for exactly this: in 3 to 5 days, we map your needs and deliver a prioritized AI roadmap.
How much does a proof of concept cost?
€5,000 excl. VAT, flat rate. You get a working prototype, tested on your real cases, usable in production. 1 to 2 months of development. If the project needs to go further, we move to the agile Studio (€2,500 excl. VAT/month) or to a fixed package depending on the scope.
Do you handle the design?
Yes, end to end. UX research, wireframes, UI design and integration — everything is done in-house. We don't separate design from code. The result: interfaces that are beautiful AND functional, built for the legal profession.
Do you integrate AI into projects?
It's our specialty. We integrate Claude, GPT or Mistral depending on the need — document generation, classification, summarization, augmented legal research. We connect LLMs to your business data via the MCP protocol for reliable, contextualized results. We built MCP Factory and Supernovia: legal AI is something we practice every day.
What is MCP?
MCP (Model Context Protocol) is a protocol that lets an AI model interact with external data sources in real time — legal databases, ERP, internal documents. Concretely, your AI assistant can pull a statute from Légifrance, look up a Pappers record or read a document in your DMS. We built MCP Factory to industrialize these connections: 17 connectors, more than 4.5 million documents accessible.
Who owns the code?
You do. In every scenario. Whether you host in-house or we deliver turnkey, you leave with the code, the documentation and the ability to take over maintenance on your own if you wish.
What if it changes along the way?
That's the norm. Our short-sprint method is built to absorb changes. If the scope evolves significantly, we reassess the timeline and budget together. As long as we keep talking, everything can be managed.
Can you just help me with specifications?
Yes. Functional scoping, technical architecture, audit of an existing system — it can be a first step before development, or a deliverable in itself. The audit from €1,500 excl. VAT is often the right entry point: you leave with a map of your needs and an AI roadmap, whether the project moves forward with us or not.
Another path
Not (yet) a custom project?
Maybe what you're looking for already exists — or you can build it yourself.
