About us
Our ambition is to turn our clients into Media Owners by scaling up tools, messages, services & audience interactions.

Since 2013 our sole focus has been to deliver solutions that help brands speed up their engagement strategy transformation for workforces (improving employee engagement thanks to internal communication) and clients (driving sales thanks to in-store communication).
We started with offline communication on screens placed in offices or in stores (Digital Signage) and increased the reach of their communications, adding an online layer to our customers.

Our 60+ people company is located in France (Toulouse (Headquarter), Paris, Saint-Etienne, and Tunis).

Our culture is ultra strong and oriented around:
● The Champion’s league mindset (we are always looking for being better individuals and achieving better results) for our team but also through our solutions
● The Concern for others (we care about our employees, altruist, mutual respect and listening are musts)
● The Client and service focus (we don’t want to be solution provider, we want to team up with our customers and are eager to better understand how they are using our solutions to improve it and help them achieve better results)
● The Assertiveness (the feedback culture is essential, we challenge with confidence, and we value initiatives)
