1. Introduction

Are you organizing a series of hackathons across multiple countries?
Or managing local hackathons happening simultaneously under a shared theme?

Managing multiple local events at the same time can quickly become complex: registrations, team formation, local communications, and jury evaluations can all get messy without a proper platform.

In this article, we showcase the  EU Code Week Hackathons 2025 use case, where Eventornado allowed the organizers to run multiple local hackathons simultaneously while keeping everything structured, automated, and professional.

In the EU Code Week Hackathons 2025, young participants aged 15 to 19 competed in local hackathons in Croatia, France, Greece, Italy (Florence and Turin), Lithuania, Portugal, Slovenia, Spain, Türkiye, and Ukraine. Each local hackathon was part of a single, coherent program culminating in an EU-level final.

2. Running multiple hackathons at the same time with Eventornado

Eventornado is designed to scale beyond a single event.

For EU Code Week Hackathons 2025, multiple local hackathons ran across Europe at the same time, all connected to one main program.

This setup allowed:

• One platform for the whole hackathon series
• A single admin dashboard for global oversight
• Local hackathons that operate independently, but under a shared admin dashboard
• Participants and organizers experience a seamless, consistent, and professional workflow, no matter the country.

3. One main registration hub for all the hackathons

All participants registered through one unified registration page, which was simple and professional:

• Young innovators from 12 countries signed up on a single registration hub
• Each participant selected their local hackathon during registration
• The platform automatically organized participants by country

This provided organizers with one clean source of truth, avoiding duplicated forms and simplifying participant management across all local hackathons.

4. Unlimited local hackathon tabs

Each country hackathon had its own dedicated tab, hosting local-specific content,  tailored to local needs, while maintaining a consistent look and feel aligned with the overall program.

Each tab contained:

• Local challenges and agenda
• Mentors and jury information
• Venue or online access details
• Dedicated local hackathon resources

5. Separate Discord servers for each local hackathon

Communication was kept clear and organized.

Each local hackathon got its own Discord server, so participants from one country only collaborated with peers from the same local hackathon.

This ensured:

• No mixed conversations across countries
• Smooth team coordination within local hackathons
• Clear separation of discussions, mentoring, and announcements

Overall, the EU Code Week Hackathons program still benefited from unified administration while participants enjoyed a local-focused experience.

6. Participant grouped by local hackathon

Participants were automatically marked upon registration with their local hackathon group, so organizers could:

• Filter participants by country
• Track teams and progress for each local hackathon
• Export clean reports for local and global oversight

Eventornado makes managing hundreds of participants across multiple countries fast and error-free.

7. Automated team formation rules by country

Teams were automatically restricted to participants from the same local hackathon.

For example, teams in Croatia could not include members from France or Spain

Invitations and join requests were automatically validated by the platform

Organizers did not need to monitor or correct team formation manually

This ensured fair competition and kept each local hackathon independent.

8. Unlimited admins for local hackathons

Each local hackathon can have unlimited administrators.

During the hackathon series:

• Local organizers managed participants, teams, and content for their own country
• Admins saw only their assigned local hackathon, while global organizers kept full oversight
• Collaboration across multiple admin teams was smooth and efficient

This made running 12 local hackathons simultaneously possible without confusion.

9. Local jury panels and parallel evaluation rounds

Each local hackathon had its own jury panel, reviewing only the teams from that country, and each local hackathon admin was able to set up their own local hackathon evaluation round, without interfering with the other local hackathons:

• Evaluation rounds happened in parallel across multiple countries
• Local teams received feedback from their local hackathon judges
• Global organizers coordinated the EU-level finals without mixing scores

10. Conclusions
