Our focus areas

EVENTS

Whether they are for wider public (stands, open days), targeted (press releases) or internal (seminars), our priority is to make a lasting impression. It is not because an event is ephemeral that it should be forgotten!

SPACE DEVELOPMENT

Prosigma’s historic spearhead. After more than 25 years designing and making stands and exhibitions, this area of activity has no secrets for our teams.

GRAPHICS

Creating visuals completes and finalizes the handling of your event. To illustrate and explain your messages as well as to forge your identity, the creation of visuals remains predominant in all types of communication.
