Hairiss Hierso is a French karate athlete from Besançon with a proven competitive record across European, French, World Championship, and Série A events. He brings an authentic performance-sport audience, strong France-based relevance, and visually engaging, fashion-conscious content that fits brands looking to connect with ambitious, disciplined young athletes.
Hairiss Hierso est un athlète international de karaté, alliant avec brio des études exigeantes en informatique et une carrière sportive de haut niveau. Son palmarès parle pour lui : 3ème aux championnats du monde, champion d'Europe, medaillé d'or et d'argent à la youth league, et 2 fois vainqueur des championnats de France. À seulement 18 ans, il a déjà marqué le karaté par ses performances et incarne pleinement les valeurs portées par les arts martiaux tels que la discipline et la persévérance. Physiquement, Hairiss possède une beauté et un charisme naturel, avec un look moderne et un teint métissé, ce qui correspond parfaitement aux marques cherchant à toucher une génération dynamique, connectée et soucieuse de performances. Malgré une exposition actuelle sur les réseaux sociaux encore relativement modeste, son potentiel de croissance est énorme, car il incarne des valeurs d'excellence et de diversité qui résonnent avec le public.

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics? It is the question brands ask us most, and it came up again when I joined Massimo Marinelli on the Berkida Ventures Podcast.
