BH-27AI HACKATHONBRATISLAVA SK
Never done one? Most of the room hasn't.
A hackathon is a weekend where a small team turns an idea into something that works, then shows it to people who build for a living.
- Saturday morning
Pick a brief
Three companies each set a real problem. Choose one, find your team, and argue about what to build.
- Saturday afternoon to Sunday noon
Build it
Use any AI tool that gets you there. Mentors from industry are in the room the whole way through.
- Sunday afternoon
Pitch it
Every team presents to a judging panel. The best in each track pitch again on the main stage.
The whole event, on eight pins.

Questions, answered.
Students
I have never coded. Can I come?
Yes. No coding experience is required. AI tools do a lot of the heavy lifting, and mentors sit with teams all weekend.
Do I need a team?
No. Everyone signs up alone. Teams of 2 to 5 form on Saturday morning, and you can join up with friends then.
What does it cost?
Nothing. Meals, snacks and drinks are included on both days.
Are AI tools allowed?
Yes, building with AI is the point. Projects must be built during the event, and personal data about real people never goes into an AI tool.
Parents and schools
Who is responsible for the students?
Every school group comes with a responsible adult, about one for every 5 to 8 students, with signed consent from parents and the school.
Who runs BratHacks?
BISB is the official host. It receives sponsor funds, signs supplier contracts and holds registration data in line with GDPR. The organisers are four BISB alumni.
Where do students sleep?
Local students can go home. Out-of-town students stay at BISB if the school approves, or in a nearby hotel, with adults present all night.
What safety measures are in place?
A named BISB safeguarding lead, a first aider, a code of conduct, emergency contacts, and a check-in and check-out log for every student.
Close the circuit. Take a place.
120 places, first come, first served. After that the form adds you to the waitlist.
