Our goal is to make Bratislava better

The vision of the city of Bratislava is to be a resilient and sustainable city that provides its residents with a pleasant place to live. As part of the Climathon challenge, the city is trying to improve the efficient functioning of the city's infrastructure and create services that support the city's climate resilience. Innovative solutions are based on live city data and valuable data from partners, which can only be accessed during the Climathon event.

Frequently asked questions

What is Climathon Bratislava 2022?

Climathon Bratislava is the largest innovation event that brings together hackers, mentors, city exerts, data scientists and business leaders from Slovakia.

What if I don't have a team?

You can still register as a solo hacker and we will try our best to match you with other solo hackers who are looking for a team. 

On October 6, 2022 at 17:00, a Kick off event will be held for Climathon participants and interested individuals. At this short event, you will get a unique opportunity to learn more about the Climathon challenges directly from the experts, get recommendations or inspiration for the direction of your solutions and ask your additional questions. At the same time, you will have the opportunity to meet other "hackers" and build or expand your team for the event. Register for Kick off here.

You can register for Climathon as a team until October 17, 2022 or until the capacity is full.
