Adria Hack Sarajevo '26 - The Overnight

Adria Hack is a curated 24-hour startup hackathon. Around 50 selected builders from across Europe and the wider EMEA region build continuously overnight, on-site, in one room and demo what they made the next day. No streaming in from home. No week-long submission window. The region has never been short of talent. What it has not had is the room: a place where the most ambitious builders are put together, given serious tools, and pushed to ship something real in one sitting. That is what this is. Adria Hack is the first event of Adria Tech Arena, a regional platform launching from Sarajevo and expanding city by city.
