What we do
“Every line of code counts.”
Needs analysis and functional scoping
We start from your business, not from the technology. Through workshops, interviews and flow analyses, we model your needs to build a relevant and sustainable solution.
Software Architecture and Development
Front-end, back-end, database, API… Our developers design robust, scalable, and secure applications. Every line of code is written to serve your purposes.
Product vision and digital strategy
We analyse together the strategic challenges of your business lines to define the priority objectives to be achieved. We then help you build a strategy for the development of your digital tools and the impacts on your organisation

Tailor-made UX/UI
Tailor-made software deserves the right experience. We integrate UX/UI design and accessibility issues from the very first mock-ups in order to promote adoption.
Deployment, maintenance and evolution
We ensure the production launch, technical follow-up and evolutions of your solution. In agile mode, with short cycles and a quick return on investment.
Our approach
User-oriented design
End users are involved from the earliest stages of the project. The software is designed with them, for them.
Facilitation of change
Your organisation evolves over time. We design software that can evolve with your needs. For each project, we systematically adopt a collaborative approach, both within our teams and with all partners.
A.I.
We leverage A.I. to facilitate application development on the one hand and as a block of the solution on the other
Agile methods and transparency
Frequent deliveries, regular returns, controlled budget. You test, validate and manage each stage of the construction for quick results. At the technical level, we are setting up a platform to streamline and make the development work more reliable: CI/CD with automated testing, control of the security and performance of the developed applications, etc.
