Lucien a commencé à développer sur iPhone en septembre 2011, alors fraichement diplômé de l’EFREI. Il a travaillé pour 2 startups avant Yubo, toutes 2 spécialisées dans la création musicale. Durant ces expériences il a pu sans cesse évoluer et apprendre à maitriser l’ensemble l’écosystème iOS.

Aujourd’hui, chez Yubo, il transmet son expérience à son équipe afin de rendre l’app iOS la plus plaisante possible pour les utilisateurs de Yubo.

Passionné par les sciences et les langues dès son plus jeune âge, Arthur obtient un bac S section Polonais et Mathématiques avec mention très bien au lycée international de Saint Germain en Laye. Il enchaine avec une prépa Mathématiques et Physiques au lycée Louis Le Grand où il découvre les joies de l’informatique. C’est au cours de ses études d’ingénieur à l’école Centrale Paris qu’il rencontre Sacha et décide en collaboration avec Jérémie de créer leur startup à la fin de leurs études. En tant que CTO de Yubo, sa vision est de définir et mettre une infrastructure technique robuste pour accompagner la croissance de l’entreprise tout en permettant à chaque membre de l’équipe tech de se développer et grandir conformément à la stratégie et la culture de l’entreprise.

Sacha a toujours voulu entreprendre. Avec Jérémie, il lance sa première application à l’âge de 18 ans, en parallèle de ses études à Dauphine. Il intègre ensuite Centrale Paris, où il fait la rencontre d’Arthur, qui les rejoint pour la création d’une deuxième app. Passionnés par les app consumer et toujours avec l’envie d’améliorer les interactions et les connexions entre les gens, ils créent tous les trois yubo en octobre 2015.

En tant que CEO, le rôle de Sacha est de piloter la stratégie globale de l’entreprise en d’en définir la vision.
