Severin Zemp is Stark Jiu-Jitsu’s head coach. He is a 5x IBJJF European Championship medalist (2x gold at brown, 2x silver at black, 1x bronze at brown) and received his black belt from the Brazilian 12x world champion Caio Terra in 2022. 

Sevi has on multiple occasions traveled around the world to train jiu-jitsu including at the Caio Terra headquarters in San Jose, Carpe Diem and Triforce in Tokyo, Bali MMA in Bali, and Gordo, Terrere, Checkmat Copacabana, and Blackbelt Academy (with Felipe Costa) in Rio de Janeiro.

Sevi is a seasoned BJJ Globetrotters participant and has taught classes at many of its camps (Austria 2023, Estonia 2023, Austria 2024, Austria 2025). He spent the last 7 years as a head coach in a different Zurich-based gym before branching out on his own in 2023. 

As a light featherweight, Sevi’s teaching emphasises precision and is technique-based rather than force-based. He aims to teach excellent jiu-jitsu that will work for all individuals (hobbyists and competitors alike), with a strong emphasis on—above all else—having fun.
