Sephora, Nexity, Sanofi, Total...

We cooperate with agencies on behalf of numerous companies. Our areas of intervention? From simple advice to framing, from monitoring Calls for Tender (development of prototypes / proofs of concept) to facilitating client workshops, to the drafting of functional & technical specifications. We also handle subcontracting, in part or in full, of productions for your client.

Digitalization, dematerialization...

Our goal is to optimize your internal processes, by creating tailor-made solutions to facilitate storage, optimize data flows, save you time, and reduce your costs. After a consulting phase and design workshops, we define together the tool that will best meet your needs: intranet, extranet, CRM, staffing tool, invoicing... and any other imaginable area. We also assist in the installation, server configuration, and hosting, and we organize internal training to facilitate the handling of the created tool.

Smart Contracts, Web3 interfaces

In the complex universe of blockchain, we accompany you up to the live phase of your project. Whether it's developing a private blockchain for a corporate initiative or harnessing existing blockchains through smart contracts, our expertise will turn your vision into reality.

Our area of expertise doesn't stop at blockchain. We also create intuitive web interfaces to make your Web3 projects easily accessible and understandable, transforming complexity into simplicity.
