No, submission is not mandatory.However, we encourage you to submit your work - judges might see potential you don’t!

This is required for both evaluation and ownership clarity.

A mentor is an expert who supports participants by sharing knowledge and experience during the hackathon.

Mentors help with both technical and business-related questions, support idea development, and guide teams when they get stuck.

They also help teams gain a broader perspective and refine their solutions.

Simply fill out the application form, describe your expertise, and tell us how you can support participants.

Mentors will be available on-site in a dedicated mentor zone.

You can also reach them via Discord - in task channels or through direct messages.
Mentors are marked with “MENTOR |” and a special role.
