Four promises, one studio

Senior hands on every line that ships.
No remote oversight, no handoff chain. The engineer who scopes your project is the one who owns every decision that reaches your stack, with ten years of production experience behind each call.
Scoped in 48 hours. Shipped in weeks.
You bring the problem Monday. By Wednesday you have a fixed proposal. By month-end you have working code running in your stack.
Your code. Your IP. Yours from day one.
No proprietary platforms. No dependency traps. No seat licenses to renew. Everything we ship lives in your repository, under your name.
Paris. France. GDPR-native by default.
Our agents run on Scaleway, exclusively on French soil. Your data never touches a server outside the EU. Zero cross-border transfer, zero loopholes.

A small studio with a serious engine. The agents handle the volume. Senior engineers own the decisions. You get shipped outcomes on a predictable timeline, and full ownership of every deliverable.

01 · What we ship

Hard problems,
shipped clean

Four practice areas. One codified methodology. Senior engineers in the loop on every line of code that reaches your repo.

A / 01

Data you can trust

Pipelines, dashboards, and data infrastructure that survive Monday morning. Real-time, automated, and clean enough that your team stops arguing about numbers and starts acting on them.

A / 02

Production ML & decision systems

Recommender engines, classifiers, forecasting, agents. We build them when they make sense for your business, with the same senior oversight as the rest of your stack. Every model choice justified. Every run observable.

A / 03

Software that ships

Internal tools, apps, platforms. Code written by agents, reviewed by seniors, owned by you. We hand over a working product, not a requirements document or a pile of tickets.

A / 04

A roadmap, prioritized

You bring a list, or we build one together in a short discovery workshop. Each item gets weighed on difficulty and business impact. The highest-leverage ones ship first. The rest get a clear reason they can wait.

02 · Method

Why it actually works

Our agents aren't generic tools bolted on. They run on a proprietary methodology, codified in-house, reapplied every engagement. Plan, build, review, improve. The right model for each step, not whatever is trending this month.

0

Rework Tolerance

Our agents stop the moment a defect is detected. No patching, no workarounds. Problems are analyzed at the root and fixed before anything moves forward.

Quality Checkpoints

Every deliverable passes through five independent quality dimensions (safety, quality, delivery, cost, compliance) before it reaches you.

Continuous Learning

Each engagement unlocks new playbooks and sharpens the methodology. The patterns get better every mission. Your data never leaves your stack; only the lessons in the process do.

Proprietary methodology. Battle-tested in-house. Every decision logged, every lesson captured, every build reviewed.

Modern data work ships in weeks, not quarters. The toolchain changed. Our pricing reflects that.

04 · Process

How we work

From a list of problems to a working solution. Four movements, no ceremony.

01

You bring the problems

One call. No jargon. Bring us a list of what's broken or missing, not a single ticket.

02

We map and prioritize

You bring a list, or we build one together in a short discovery workshop. We weigh each item by difficulty and business impact. The ones that move the needle fastest go first. The rest get a clear reason they can wait.

03

We scope in 48 hours

A clear proposal within two working days. Fixed price, defined outcome, no surprises.

04

We build. You watch.

Weekly demos of working code. No status decks. Everything we build is yours. Extend the scope or walk away.

05 · Trust

Four commitments

Senior oversight on every engagement. Human review before anything ships. French-sovereign cloud by default. Code that stays yours, no exceptions.

Senior-Led, Always

Every project is supervised by a senior engineer with 10+ years of experience. Agents handle execution; humans make the decisions that matter.

Reviewed before it ships

Acceleration is on our side. Accountability stays human. Every model, transformation, and line of code passes deterministic tests and senior review before anything reaches your repository.

Your Data Stays Yours

Our stack runs on Scaleway, a French cloud provider operating exclusively on French soil. Your code, your data, your intellectual property stay GDPR-native with zero cross-border transfer.

No Lock-In. Ever.

Start with a one-month pilot. Scale when it works, stop when it's done. We deliver working code you own, no proprietary platforms, no dependency traps.

06 · FAQ

Frequently asked questions

Answers to the most common questions about the q4o model.

Who is actually doing the work, a robot?
Agents handle the heavy lifting: building, testing, documenting. Every decision and every delivery is reviewed by a senior engineer with 10+ years of experience. Think of it as a senior architect with a tireless team that never sleeps.
How are your prices usually lower than a big firm's?
We don't carry pyramid overhead. Every project runs with a senior engineer and a stack of agents that already know how to execute. You pay for shipped work, not ramp-up time. The difference comes from a leaner model, not from cutting corners.
What if the project doesn't work out?
Start with a 1-month pilot on a contained scope. No long-term contract. You keep everything we build: code, tests, documentation. If it works, scale up. If not, walk away with zero sunk cost beyond the pilot.
Is my data safe?
Yes. Our stack runs on Scaleway, a French cloud provider operating exclusively in France. Your code and data stay fully GDPR-compliant and never cross borders. We sign NDAs before any engagement, and you own 100% of what we produce.
I don't have a technical team. Can you still help?
Absolutely. Many of our clients are business leaders without in-house tech teams. You explain the problem in plain language. We handle everything from architecture to deployment. You get a working product, not a requirements document.

Tell us what you're trying to ship.

A 30-minute call. No jargon. We come back with a scoped proposal in 48 hours, free of charge.
