Prototype
€12k — €25k ex VAT
To test an idea, run an investor demo, validate a feature. No systematic tests, minimal documentation. We move fast, we learn.
Estimate
How much will your project cost?
No rigid packages. Every project is custom-quoted after a one or two week technical scoping. Here are the ranges to get the conversation started.
Innovation Tax Credit (CII)
Studio approved by the French government under the CII scheme. Project eligibility and tax treatment must be confirmed with your tax adviser.
Three engagement levels
From prototype to product that lasts.
We quote case by case after scoping. Here are three orders of magnitude depending on what you want to ship — not packages, just reference points to start the conversation.
MVP
€35k — €70k ex VAT
To launch a real product to your first users. Basic tests, prod-ready, 1-month post-launch warranty. The minimum viable to ship to the stores with confidence.
Scalable
€80k — €160k ex VAT
For a product designed to evolve, scale and remain transferable over time. E2E tests, full monitoring, a design system and stronger documentation.
Our process
How we estimate.
01
Technical scoping
One to two weeks billed at our daily rate. We identify the real risks, validate the target architecture, document the decisions.
02
Detailed quote
Itemised quote, schedule, architecture. No commitment until you sign. If we're not the right team, we'll point you elsewhere.
03
Build
Weekly demos. Reviewed PRs. Automated tests. CI/CD. Monitoring in production from day one. 1-month post-launch warranty included.
Daily rate
€750 ex VAT per day. No surprise.
This rate is the basis for scoping and time-based engagements. The quote sets out the scope, estimated days and any infrastructure or licence costs.
Evolutive maintenance
Without regular updates, an application gradually becomes exposed to compatibility issues, vulnerabilities and incidents. Our recurring contracts organise that ongoing work.
