Europe's biggest hackathon, 48 hours and 2,000 builders at Hype Areena in the Helsinki metro, this year themed "European Tech Renaissance". Tracks span AI, hardware, defence, fintech, health and quantum with partner challenges from Arduino and Lifeline Ventures. Teams ship a working prototype against €100,000 in prizes while mentors, judges and investors from across Europe prowl the floor. Applications close 25 October; worth flying in for if you build, want cofounders, or want to be seen by the people hiring and funding at the next paradigm.
