What clients say
“Very clean, well-documented integration, attention to detail, great autonomy and good communication, with a real ability to understand what is at stake and even challenge the initial ideas with new proposals. A clean and solid result.”
“The scoping of the project was clear, the discussions simple, natural and above all very effective. It is clearly the kind of collaboration that saves time and brings peace of mind.”
“No waffle, no vague recommendations. A deliverable you open and execute.”
“Very professional and attentive to my needs, Visionlab delivered very precise work on my website. The ideas they proposed and brought in were essential to the creation of this website.”

03 · How we work
A scoping workshop with your teams. We learn how the business really runs, and you leave with a roadmap.
Two-week sprints. Each one ends with a demo of a working version, and a test environment stays open to you in between.
We put the product in production, host it and watch over it. Your teams are using it, not waiting for it.
Maintenance and new sprints as needs appear. Or a full handover of code, documentation and training: you are never locked in.
04 · Who we are
One senior lead, a crew of AI agents and a network of specialists: Visionlab moves at the pace of a full team, with a single point of contact.
We build what established companies are missing: business applications, AI wired into the tools you already use, SaaS products and websites. You do not need a tech team of your own. We are that team.
AI agents write, test and review under the direction of a senior engineer, who answers for everything that ships. When a project calls for it, trusted independents join in: designers, developers, content and data specialists.
01
Agents do the heavy lifting, a senior makes the decisions. You see a working version every two weeks, not a status report.
02
A direct line to the person who designs and builds. No account manager, and nothing lost between the brief and the code.
03
We host, maintain and grow your product for as long as you want. The day you prefer to take it over, the code, the documentation and the training are yours.

05 · Before you ask
Your project never depends on one person being there. The code lives in your own repository from day one, it is documented and tested as it is written, it only uses mainstream technology, and a senior developer from our network can take it over.
Read the full answer →Agents write fast, but they do not decide. Architecture and security choices are made by a senior engineer, every feature is covered by automated tests that run at each change, and a dedicated security review comes before every release.
Read the full answer →You get a global quote before the project starts for everything that can be estimated, and a provisional budget for what cannot. A two-week sprint costs around €5,000 on average, and you can ask for a financial update at any time, or get one at every sprint.
Read the full answer →Count two to three months for a first version in production. You will not wait that long to see it, though: a working version is demonstrated every two weeks, and a test environment stays open to you from the start.
Read the full answer →Sometimes you should not, and we will tell you when an existing product does the job. But AI and modern development have changed the cost of custom software so much that there are few reasons left to keep bending your business around a tool made for someone else.
Read the full answer →No technical skills at all. We need one person who knows how your business really runs, available about half a day a week to answer questions and try what we build. The technical side, from architecture to hosting, is ours.
Read the full answer →We host, maintain and keep improving your product for as long as it suits you. And because the code, the documentation and the training are yours, you can take it over or hand it to someone else whenever you choose.
