15 years
of science communication

Agent Majeur is a science communication agency founded in 2008. Since then, the research landscape has transformed. Scientists are under increasing pressure to publicise their activities, seek out funding, forge partnerships, and so forth. To navigate these tasks, they must cultivate their communication.

value and communication

‘Adding value to science.’ Why would a science communication agency choose such a slogan? Research and innovation bring value to institutions but also, on a grander scale, society. Yet for this, funding is often needed, as is time for the integration of the solutions they provide. By putting research and scientific breakthroughs under the spotlight, Agent Majeur helps to add even more value to projects.


At the office or in the shower, we put our heads together and brainstorm with clients, to come up with ideas (almost) 24 hours a day.


When faced with a problem, we ask ourselves the right questions, in the right order. Because that’s how you come up with the right answers!


Because science certainly doesn’t work on approximations, we do background research on the subjects we work on.


We consider ourselves lucky to be in a fantastic line of work, finding ideas that engage minds with lasting impact.

The history
of Agent Majeur

Our story begins with an epiphany . Alexia Youknovsky is focused on inventing her dream job, one that will allow her to merge her different skills. With a degree in chemistry, experience in research and consulting, and after working for 6 years as a comedian, this unusual career inspires her and something clicks. She elects to create a new type of company, a science communication agency.

Swaying the market

Being a pioneer is not easy, especially not at first. « Why help scientists to communicate? They do it all the time! » This question returns constantly when Alexia undertakes this entrepreneurial venture. As it turns out, Alexia’s insight was spot-on and she steadily wins over her market.

Getting a head start

But being first has its perks, including getting a head start. Agent Majeur is familiar with the research community, its actors, how they work and they communicate. Our agency has always known what works in our field, and we keep a close eye on new trends.

Making the right decisions

Nowadays, the question our team must now answer is not « Why? », but « How? ». How can we promote activities in research and innovation? Effective communication has become essential. Thanks to our expertise and our support, our clients are able to make the right choices.
