Cities must be prepared to adapt to rapid changes and emerging challenges, and they need smart solutions that help ensure a safe living environment, seamless services, and strong communities in all situations.
To achieve this, cities must continuously strengthen their resilience, enhance cooperation, and adopt innovative technologies. The City Resilience Hack brings together fresh ideas and practical solutions that help cities prepare better, respond faster, and support people when they need it most.
The hackathon offers a €75,000 prize fund, with the best teams receiving cash prizes, opportunities to further develop their solutions with cities, and access to test environments and pilot projects.
City Resilience Hack is organized by the city of Tallinn and Tehnopol with partner cities: Valencia, Helsinki, Dnipro and Lviv.
