We’ve got you covered! During the night, there will be a dedicated sleeping room where you can rest undisturbed. We recommend bringing a sleeping bag or blanket for maximum comfort.
Do I need a team to apply?
Not necessarily! While we encourage you to form a team before the event (it’s great if you already know your teammates), you can absolutely apply as an individual.
We’ll help you find teammates at the event during our team-finding session after the opening ceremony, where individuals and partial teams can pitch their ideas and connect with others.
Remember: Each project must be submitted by a team of 2-4 participants.

All teams must consist of 2, 3, or 4 people.
Each attendee must be a member of exactly one team at the Hackathon. You cannot work on multiple projects or be part of multiple teams.
I am under 18. Am I allowed to attend?
Yes, you can attend if you will be at least 16 years old at the time of the event.
However, if you are under 18 during the Hackathon, we will need your parent’s or legal guardian’s written consent. Once you confirm your invitation, we will send you a consent form to be signed and submitted at registration.
By hacking, do you refer to breaching security?
Definitely not! Hacking is a slang term for creative coding and building tech solutions.
From Wikipedia: “The word ‘Hackathon’ is a blend of the words ‘hack’ and ‘marathon’, where ‘hack’ is used in the sense of exploratory programming, not its alternate meaning as a reference to breaching computer security.”
Unleash your creativity in a high-energy, 24-hour Hackathon surrounded by 150+ brilliant minds, industry leaders, and endless inspiration. Compete for amazing prizes, receive expert mentorship, and turn your boldest ideas into reality!
