Headlinker est la plateforme qui permet aux recruteurs professionnels d'accélérer leurs placements complexes et de valoriser enfin leur base de candidats. En pleine expansion 🚀 Au-delà de la plateforme, on accompagne la profession sur deux fronts : 🤖 Formation à l'IA « Le pied à l'étrier » — en 2 demi-journées, en direct, je forme les recruteurs à créer leur propre assistant IA, branché sur leurs outils (ATS, CRM, LinkedIn…) et sur leur méthode. Pas une formation théorique : ils repartent avec un système installé qu'ils savent faire évoluer seuls. Déjà 5 cabinets accompagnés, avec des retours qui parlent d'eux-mêmes : « Claude m'a dit : tu as échangé avec un candidat la semaine dernière, il correspond parfaitement, il faut que tu le proposes. Il ne s'était pas trompé. » — Pascal Rebora, ATLas Recrutement « Avec le second cerveau, toute l'information que l'on traite est concentrée au même endroit, et vraiment réutilisable. Ça crée un actif, et ça dépersonnalise le cabinet : notre expertise n'est plus seulement dans ma tête. » — François-Marie Delétoille, Capstone Conseil 🤝 Le Business Club Headlinker — une communauté triée sur le volet : 1 500 recruteurs rencontrés, 430 membres sélectionnés qui partagent missions, candidats et bonnes pratiques pour faire plus de business ensemble.
