No, the Hackdays are not only for developers.
We welcome designers, analysts, journalists, researchers, energy experts, students, and anyone curious about energy innovation.
You may create your account during the registration process or directly via this link.
Participation in Hackdays is free of charge, thanks to the generous support of our sponsors and partners. We provide all the essentials—including meals (starting with breakfast), electricity, high-speed internet, and workspace infrastructure.
To minimize no-shows and ensure a spot for everyone, a small committment fee is required when reserving your ticket; this will be fully refunded within two weeks after checking-in at the event.
No, that’s not necessary either. It is important that you contribute to the success of your chosen project and discuss with your team when and where you work.
No, this is possible, but not required.
At the beginning of the hackathon, various project ideas and challenges will be presented. You can work on the project idea that inspires you most.
The primary language of the event is English. However, when working in your individual teams, you are welcome to use whichever language your group prefers.
Most importantly: Come with a passion for energy and data!
Please remember to bring your laptop. If you are traveling from outside Switzerland, ensure you have a power adapter (Type J) to stay connected.
We’ve got the rest covered: we will provide all the necessary working materials—including paper, flipcharts, and Post-its—as well as plenty of food and drinks throughout the event.
We want you to have the best possible experience during the event. We will cover the costs for a hotel stay from Thursday to Friday for all active Hackdays participants. Please be sure to book the ticket with overnight stay included.
