Developers, project managers and CTOs, trained in AI and embedded in your teams,
backed continuously by our senior engineers and developers. From one person to a full team.
Case study
A GDN team embedded over the long run, which modernised the platform towards an API First architecture while leaving control with the in-house teams.
The team arrives with its own engineering framework: automated tests, a unified error model, auto-generated API documentation. And in Done With You mode, the in-house teams stay able to evolve the system themselves.
150 API endpoints planned and delivered with no break in productionWhat the reinforcement delivered
The same team worked on several successive projects for the group: the consultant management platform, travel expense management and securing access with a second factor.
Your developers know what to do. They simply do not have the time to do it, and the trade-offs are becoming painful.
The need is here now. A hire means several months, a long commitment and a bet on future workload.
A technical lead, or simply someone who steers. Not necessarily full time, but genuinely present.
You compose the mix to suit your need, from a single person to a full team, and the mix changes as your project moves through its phases.
From one developer to a whole team, depending on your workload. Selected, then trained in our AI practices. They work with premium models and coding agents, framed by our in-house framework.
Added capacity
They scope, break down and keep the pace, with AI tooling on specification and quality. The link between your business and the code. Very often part time, and recommended if you have no project manager in house.
Day-to-day steering
Two modes: hands-on in the code with the team, or hands-off on technical direction, architecture and hiring. Often on a fractional basis.
Technical direction
How we work
These are not profiles sent to you one at a time. Every developer, project manager or CTO keeps our AI framework, our standards, our senior engineers and developers behind them. A team arrives, not a temp.
Your tools, your rituals, your stack and how your teams already work. We adapt to you, not the other way round.
People who join your rituals (daily stand-ups, reviews, steering committees), not a remote ticket queue.
Our profiles are selected, then trained in AI on our in-house framework. Once there, they align practices and train your own teams.
Capacity scales up or down with your project phases, with no hiring to carry and no workload plan to absorb.
Development capacity is not delivered the way a project is. What counts is what the people bring with them when they arrive.
When a subject calls for more brains or more hands, the person working with you brings in our senior engineers and developers. You are not paying for a pair of hands: you get access to the whole workshop, with its tools and its reflexes.

View the case studyOur developers, our project managers and our CTOs are our colleagues. We treat them well, as people, and we expect the same from the companies we lend them to.
This is not a stylistic clause. It is what separates a team that invests itself in your product from a team that runs through tickets. In practice: a named counterpart, a seat in your rituals, and the right to say when a request makes no sense.
In return, you get people who stay, who know your business within a few weeks, and who warn you before the problem arrives.
Depending on the workload and how long it lasts, extra capacity is not always the right answer. We will tell you before proposing anything.
