Wondering what kind of hackers are needed to take on the challenges? Find them here, but please don’t forget, the only really important condition for you as a participant: planet earth lover! By the way, in our FAQ we explain in more detail that there are really no requirements to take part at the Climathon.

  • Developer: Programmers who turn thoughts into code. Only the input speed of your keyboard sets you limits.
  • Engineer: With a deep scientific background you build the complex engine room of any technical project.
  • Data Scientist: You and data, it’s a long story. A mixture of data magic and a touch of AI.
  • Maker: Loves tinkering around with hardware and IoT. Your hands start to itch when you hear a great idea.
  • Idea Generator: You spark creation with your original ideas and understand the problem at hand.
  • Superpower: Not techie or a designer, but your magic touch will bring projects to life.
  • Designer: In your skillful hands, dashboards and applications gain clarity and style.

Teams of 3 to 7 people work together on a project idea.

If you don’t have a complete team yet, don’t worry, you can register as an individual participant in the application process and then find teammates before the event in our slack community or during the first day.

Tickets are free of charge. You pay 10€ for the tickets in our ticket shop, but you get 10€ refund in cash when you show up at the event. More information can be found in our FAQ.
