24 hours of hacking inside Norrsken House on a climate-action brief tied to the Paris Agreement, bracketed inside Norrsken Impact/Week. Teams of 3-4 (apply solo and get matched) build with AI and open-source tooling, with pitches on October 15 to a jury of impact investors and operators from the main stage. Participants get full access to Impact/Week itself, so you're hacking in the same building as Europe's institutional impact crowd. Travel reimbursement up to €400 per person for selected builders, waitlist opens when the primary slots fill.
Hackathon Tuesday 13 October 2026 · 15:00 · Norrsken Foundation
