For leaders who already have a business or product up and running.
Outgrowing your no-code tool? We rebuild it in code without stopping your business.
Already paid twice for the same work? Here, a costed scope first, then a demo every sprint.
Code nobody understands? We audit it, keep what holds up and rebuild the rest.
Typing the same data five times? Your tools finally talk, and the rest runs itself.

“We're going to talk about AI, development, digitalization, but I think we shouldn't forget the human aspect and that's what I found with PeakLab. This proximity, this human support. I needed advice, not just an executor.”

We get to know each other, we understand your business and your project. By the end of the call, you know whether we can help you. And so do we. No pitch, no pressure.
The foundation of the project: we break down your processes, your constraints and your 2-year vision to produce precise, costed and actionable specifications, even if you decide to hand them to someone else. It's a service in its own right, billed as such, on quote.
Sprint-based development with a test environment available at all times. You follow progress in real time and test with your real data. One meeting per week, a direct channel with the team.
Production launch, video training, complete documentation, 30-day guarantee. Then we grow the application with you, brick by brick, without ever rewriting everything.
Can't find your question?
Ask Lucien, PeakLab's CEO, directly during a free discovery call.
We tell you the truth from the scoping phase: what's feasible within your deadline, what isn't, and what we can break down to deliver the essentials first. A schedule that holds beats a promise that fails.
The right time is before your current tool breaks, not after. If your business is growing and your processes are barely keeping up, waiting costs more than starting. And a scoping phase can be planned now for a development in 2 or 3 months.
Great: we don't throw anything away on principle. We audit what exists, keep what holds up, and rebuild only what needs to be. Taking over code is a separate, scoped and quoted mission, not a surprise along the way.
That's exactly what we build it for. Architecture designed to handle increasing load, documented code, and features added brick by brick without rewriting everything. We grow the application at the pace of your business.
We know: a good share of our clients arrived burned. That's why we work in co-construction: a test environment available at all times, documented code, full ownership from day one. You see everything, all the time. Trust isn't promised, it's observed.
Every project starts with precise scoping: scope, budget, deadlines, success criteria. You test the application with your real data before production launch, and delivery includes a 30-day guarantee. No black box, no bad surprises.
It's the opposite of our model. Code 100% your property, complete documentation, your teams trained at delivery. You can leave whenever you want. That's precisely why our clients stay.
