Our history

Specialist in the development of vehicles, products and machines,
DEMS associates the creativity of the design with the rigor of the engineering,
at each step of the project development.


An ambitious bet...

After 12 years of collaboration within an International Group, Patrice Besson, Engineer and Thierry Sauvaget, Designer, wished to join their skills in order to develop a process where the duality design / engineering becomes inseparable. A time saving and a certain investment for the clients, which pushed the associates to set up a new methodology ...

It was then they decide to create in 2012, the company DEMS, Design & Engineering Office with an innovative approach mixing design and engineering, to keep the idea inventive until industrialization. This particularity is the result of an observation where the technical feasibility of a project wasn’t always included in the design process.

Thanks to this "synapse methodology", the synergy of design and engineering guarantees, from the beginning of the project, the creativity and the feasibility of it.

Controlled growth

Initially composed of 2 managers, the company doubled its workforce in 2014. Today, 5 years later, DEMS has about forty people, has many different and varied skills which allow the company to consolidate its expertise. Located on 2 sites, one near Lyon, the other close to Nantes, DEMS has a national presence to ensure greater responsiveness and a close relationship within its clients.
