About Helsinki · September 2026
Helsinki is in a builder-heavy pre-Slush stretch, with Aaltoes running back-to-back hackathons through September. The Prompt Marketing Hackathon on Sep 26 and DAWN FALL '26 on Sep 28 are both Aaltoes-run and worth the trip if you're in town. The main event arrives Nov 18: Slush 2026, the densest founder-investor matchmaking conference in Europe, with 20,000+ pre-booked meetings and 3,500 investors across two days.
