Željko Hudoletnjak is a Croatian entrepreneur and co-founder of Kupyo, an innovative video-first marketplace that combines elements of social media, e-commerce, and artificial intelligence. Trained as an architect, Hudoletnjak previously gained extensive experience with digital platforms such as Njuškalo, Posao.hr, and Oglasnik, where he led teams and managed major projects.

Kupyo allows users to browse products through videos, featuring integrated AI avatars and personalized recommendations, creating an interactive and authentic online shopping experience.

Kupyo is currently expanding globally, aiming to set new standards in online retail.
