City Resilience Hack

September 24-25, 2026

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. Taking place in Tallinn, 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 best teams will have the opportunity to pilot their solutions in one of five participating cities – Tallinn, Helsinki, Valencia, Dnipro or Lviv – with a total funding pool of up to €75,000 available to support implementation and maximise the impact of their solutions.

City Resilience Hack is organized by the City of Tallinn and Tehnopol as part of Estonian Defence Week, in collaboration with partner cities Valencia, Helsinki, Dnipro, and Lviv.
