At the age of 14, Hojac discovered his passion for the mountains during a language stay in Lower Valais.
The culmination of this three-year training period was an expedition to the Tian Shan Mountains in China, where the team completed several first ascents.
This project was documented by Swiss television and later aired as the documentary "Hoch Hinaus - The Expedition Team" on SRF 2.

In July 2021, Hojac featured in the film The Soloist VR, where he assisted Alex Honnold in free solo climbs across the Alps and Dolomites.
