Your business runs on spreadsheets, email threads and tools that don't talk to each other.
We build the AI systems that replace them, around your process, not a template. AI agents, automations and business applications, live in four to eight weeks. No-code and low-code where they are faster, custom code where they are not.

Why now
A build like this used
to be out of reach.
A bespoke internal tool used to take nine months and an enterprise budget. With AI in the development chain, it takes four to eight weeks. That is what makes it pay off for a thirty-person company, not just a corporate one.
What we build with AI
Five systems.
Each one built around your process.
AI that does the work, not AI that chats. Each system comes with its timeline and its proof: where we have shipped, we say what and how much. Where we have not published a case yet, we say that instead of borrowing someone else's number.
01 · Revenue AI
No enquiry left to go cold.
Every inbound enquiry, from email, forms or phone, is qualified, enriched, followed up and routed into your CRM around the clock, with a draft reply waiting for your approval.
Closest system we run: Inboxer, which triages an inbox and drafts replies on Gmail and Outlook, every action approved by a human.
02 · Back-office AI
The admin runs in the background.
Quotes, invoices, contracts and attachments read, checked and filed into your tools: accounting, CRM, shared drive. Human sign-off wherever you want it.
In production: the claims and reimbursement CRM we built for Nostrum Care, with its n8n automations. Volumes not published yet.
03 · Knowledge & RAG
Your procedures answer, with the source attached.
Contracts, procedures and past cases turned into a knowledge base the whole team can question. Every answer quotes the paragraph it came from, so it can be checked rather than trusted.
No public case study yet. We say so rather than show someone else's number.
04 · Live reporting
The whole company, visible in one place.
Pipeline, margin, cases by stage, team workload, marketing return: one living dashboard fed by the tools you already run, instead of reports pulled by hand for the Friday meeting.
In production: Venture Deal, a deal-flow and pipeline platform for venture funds and business angels.
05 · Bespoke AI & your own model
When the leverage fits no category.
Agents that act in your tools, vision that reads photos and documents and, when no existing model can do the job, a model trained for you. For Mamlo we fine-tuned our own with LoRA on MLX, because no general model writes Surayt, an endangered Neo-Aramaic language: a 430,000-word pretraining corpus, 53,000 instruction pairs, run on Qwen3-4B and Gemma-3-12B and scored with chrF.
In production: Mamlo, model trained in-house · Calio, Claude Vision for 50,000+ monthly users · Inboxer, email agent.
The corpus, the two training passes, the metric we chose and the run that scored a suspicious perfect 100. Read the case study → Building a product, not an internal tool?
We also build web apps, mobile apps and MVPs for startups, with the same team and the same timeline. See pricing →

Case studies
Named clients.
Systems in production.
Nostrum Care
Claims and reimbursement CRM for a French mutual-insurance group. Member reimbursements, dispute tracking and activity reporting in one tool, handling sensitive personal and financial data under GDPR.
Olympique de Marseille
Fan and pro applications for the club, plus questionnaire tools to collect feedback across its different audiences.
Calio
Health OS in production: nutrition tracking with barcode scan and AI photo calorie estimation, plus sleep, recovery and training load.
And six SaaS products in production
Products we designed, built and still run, including our own. Translation models fine-tuned in-house, an inbox assistant, and a deal-flow platform.
Built around your business
We work with the tools
you already use.
Claude, OpenAI or Mistral, chosen per project, plugged directly into the tools you already run. No new platform for your team to learn.
We have our preferred, proven tools, and we are a certified partner on WeWeb, FlutterFlow, Supabase and Xano. We work with the others all the same.

We build your systems.
They live with you, not with us.
We take on two or three builds at a time, no more. Each system is built on your processes. That doesn't turn into a production line.
How to decide
Four ways to bring AI
into a company.
A company that wants AI in its operations has four realistic paths: a fixed-price build like ours, an AI SaaS subscription, an in-house hire, or a large consultancy. They differ on cost, on the time to a first result, and on who owns the system at the end.
| App Studio, fixed price | AI SaaS subscription | Internal AI hire | Large consultancy | |
|---|---|---|---|---|
| Cost | €2,500 to €40,000, one-off, fixed price | A monthly fee per user, for as long as you use it | A full-time salary, often €60,000 to €90,000 a year in France, plus recruiting time | Often six figures, starting with a strategy phase |
| First result | 2 weeks with Automate, 4 to 8 weeks for a full system | Days to weeks of configuration | Months: recruiting, then infrastructure | Months: strategy first, build after |
| Who owns it | You: code, prompts and documentation | The vendor | You | It depends on the contract |
| Fits your process | Built around it | You adapt to the tool | Yes, once the team exists | Yes, at a price |
| Best for | SMEs and scale-ups with one process costing time or money | Standard workflows many companies share | Companies with a continuous AI roadmap | Large groups with an innovation budget |
| Limit | Two or three projects at a time | Built for the average customer, not for you | Slow to start, hard to hire | The build is often handed to a third party |
If a standard tool already does what you need, buy the tool, and we will tell you which one. If one of your processes costs time or money and no tool fits it, that is the case for a build.
Not for you if…
- An existing tool already does what you need. We will tell you which one, and you will not need us.
- You want a strategy document. We deliver working systems, not slide decks.
- You need a team of ten from day one. We take two or three projects at a time, on purpose.
How we work
From zero to live
in four steps.
Discovery & Strategy
We dig deep into your vision, users, and goals. We map out the architecture, choose the right tools, and set a realistic timeline, no surprises.
Design & Prototype
High-fidelity wireframes and interactive prototypes. You see exactly what you're getting before a single line of production code is written.
Build & Iterate
Weekly sprints with demos. You're in the loop at every step. We ship fast, gather feedback, and iterate until it's perfect.
Launch & Support
We handle deployment, testing, and go-live. After launch, we offer ongoing support, feature development, and performance monitoring.
Questions
What you're wondering
before you call.
Is this just ChatGPT with a wrapper?
No. A wrapper answers questions. What we build acts: it reads your documents, updates your CRM, drafts the reply and waits for your approval. And when no existing model can do the job, we train one, as we did for Mamlo.
What happens to our data?
It stays in your tools and under your control. We choose the model and where it runs according to your constraints, European options included, and we write that down in the proposal before any work starts.
Is this no-code?
Not always, and that is the point. We pick the approach per project: real code where it needs to be code, no-code and low-code where they are genuinely faster. Either way the system runs inside your tools and you own what we deliver.
How long does it take?
Four to eight weeks from the first conversation to production, for a system targeting one process. Our Automate entry offer puts a first automation live in two weeks.
What does it cost?
A fixed price, set after the first conversation based on scope. No subscription, no per-case fees. Our published rates start at €2,500 for a first automated process, €8,000 for an MVP and €15,000 for a full product.
How does it start?
A 30-minute call to frame the need. If the scope is clear, we send you a fixed-price proposal and a timeline. You approve, we start.
Do I have to change the tools I use today?
No. We build inside the tools you already use, CRM, email, accounting, with no new platform for your team to learn.
What if I want to change the system later?
It runs on your side, with code you own. You can evolve it with us, with your own team, or with another agency.
