Mehdi Moussaïd's contact route, audience split and rate estimates are ready — members see them in one tap.
Mehdi Moussaïd is a French researcher and science communicator born in the early 1980s. He developed an early interest in how individual actions lead to collective patterns, leading him to pursue a PhD in behavioral biology and cognitive science. Currently based at the Max Planck Institute in Berlin, he dedicates his professional life to studying the spatial and psychological interactions of people in groups.
While already established in academic circles, Mehdi gained widespread public recognition through his YouTube channel, Fouloscopie. His breakthrough came when he began using interactive digital experiments involving thousands of participants to demonstrate social phenomena in real-time. His clear, engaging explanations of historical crowd disasters and collective intelligence puzzles quickly went viral among the French-speaking scientific community.
Mehdi's content is characterized by its high production value and rigorous scientific accuracy. He often posts deep dives into topics like 'Place' experiments, the spread of rumors, and how human traffic flows are optimized. His best-known videos involve large-scale collaborations where he asks his audience to participate in online games to observe how collective decisions are formed.
Beyond his primary role as a researcher, Mehdi is an accomplished author, having published the book 'Fouloscopie: Ce que la foule dit de nous.' He frequently collaborates with educational institutions and public science festivals to promote scientific literacy. While he does not typically engage in traditional commercial brand deals, he works closely with cultural and academic organizations to produce scientific documentaries.
There is no reliable public estimate for Mehdi Moussaïd's net worth. His income is primarily derived from his position as a senior research scientist at the Max Planck Institute and royalties from his published book. Additionally, he generates revenue through YouTube ad programs and speaking engagements at scientific conferences and public events across Europe.
His most significant signature work is the 'Fouloscopie' brand, which spans his YouTube channel and his literary contributions. He has appeared as an expert consultant for various documentaries and news programs discussing public safety and crowd management. His work often serves as a reference for urban planners and event organizers looking to understand human movement dynamics.
Fans can primarily find his long-form educational content on his YouTube channel, Fouloscopie, where he hosts his most detailed scientific investigations. For more frequent updates, behind-the-scenes looks at his research, and short clips of behavioral experiments, he is active on Instagram and Twitter. His professional research papers are also available via academic databases and the Max Planck Institute website.
Mehdi has reached significant milestones in science communication, including surpassing 15,000 followers on Instagram and over 400,000 subscribers on YouTube. His ability to turn niche academic research into a popular media brand is considered a major achievement in the field of vulgarization. He is widely cited in French media as a leading authority on the science of human crowds.

Mehdi Moussaïd is based in France and posts in French. For brands that usually means the core audience follows the same market and language, with a long tail from everywhere else — big accounts rarely stay local.
The content sits in education and tech & science, so the people watching are self-selected for those interests. That is the useful part of a niche profile: a mid-size account inside the right category often beats a much larger general account, because the audience already cares about the subject.
If you need the same audience profile in another market, the country and language lists on CreatorFanBase let you line up comparable creators side by side instead of guessing.
If you are shortlisting Mehdi Moussaïd for a campaign, these are the facts worth carrying into the brief. Everything here is stored data, refreshed on a schedule rather than typed in once.
A practical sequence: check the lead platform matches where your buyers are, check market and language, open the official account to see recent posting frequency, then ask for a media kit and rate card directly.

Mehdi Moussaïd's counts come from the platforms themselves via instagram public profile and are refreshed on a schedule; the most recent check was Oct 16, 2026. When a platform blocks a read, we keep the last verified number and show where it came from instead of filling the gap with an estimate.
Large jumps are treated as suspect: a sudden drop past our safety threshold is held back for review rather than published, which is why the numbers here tend to be lower-drama than screenshots circulating elsewhere.
