WHAT IS A HACKATHON?

A hackathon is a focused build sprint: small teams turn an idea into a working prototype in 24 hours. Research, design, domain knowledge, and clear problem framing matter just as much as programming.

WHO SHOULD JOIN?

Builders, researchers, designers, founders, students, hardware people, med/bio specialists, and curious people who want to make something real. Apply solo or with a team.

PRIZES

Prizes and award categories will be announced at a later date.

FAQ / QUERY TERMINAL
Do I need a team?
No. Come alone or with people. Team-finding runs Saturday at 10:00 on site, and starts earlier in the Discord once you are accepted.
Do I need to be a developer?
No. Designers, product people, researchers, scientists, founders, operators, storytellers, hardware builders, and domain experts all belong here. You need curiosity, agency, and the willingness to build.
I am no hacker, why should I join?
“Hacking in a hackathon” is not about cybersecurity or “hacking into the mainframe.” It originates with hackers in the 1960s–1990s who used products in unintended ways — for example, turning computers that were originally calculators into game machines. If you have adapted a product to your needs or built a prototype, you have already been part of this hacker culture.
What can I build with?
Anything. It does not have to be software.
Do I have to attend the Day 0 workshop?
On Friday, the workshop presents everything you need to know to start working and hacking with AI. Check out the slides at machine-literacy.com.
Where do I sleep?
Some people sleep; some do not. If you want to crash with local people, ask in the Discord after acceptance. The venue stays open throughout the night either way.
What do I submit?
A three-minute video about your or your team’s progress and, ideally, a working prototype.
Which language is spoken?
English for anything official. German happens naturally in the room.
