Fixed-price engagements, concrete deliverables, zero surprises.
Got an idea? We make it bankable.
No more guesswork. We turn your vision into a solid action plan: mockups, positioning, specs. You walk away with a project ready to fundraise or build.
Support tailored to
your challenges
It's the heart of the matter, so we made it our promise: our pricing is fixed-price and tied to deliverables.

Questions we get asked
No fine print, no surprises.
Why fixed-price and not day-rate?+
Because on a day-rate model, your bill explodes when things get hard — that's your risk. With a fixed-price engagement, we commit to a deliverable and a price. Our interest becomes yours: ship fast and well.
What happens if the scope changes?+
We re-scope and re-quote before touching the code, not after. Transparent, no nasty surprise at the end of the project.
You're CII-approved — what does that change?+
Up to 20% of your eligible spend reimbursed by the French government. We provide the certificate and the elements needed for your file.
Who actually writes the code?+
An in-house team in Paris, no hidden offshore. You talk every day to the lead who writes the code of your product.
Thanks to Zetos for helping us take our product to the next level at a critical stage of our growth. The team was highly responsive and listened carefully to our needs. We're really happy with the result, and we keep trusting them with ongoing maintenance and product optimisation.
