Sergi Jansa

Sergi is a product strategist with a background in industrial design and a lifelong passion for trail running, exploring mountains and refining gear since childhood. At On, he’s part of the Outdoor team within Product Strategy, focusing on athlete projects that turn real-world insights into trail footwear innovation. Inspired early on by Kilian Jornet’s journey, he still logs plenty of miles himself, ideally followed by a specialty coffee and a cardamom bun.
