Practical Info

The Hackathon will take place onsite on the 9 October 2021
The Hackathon is free of charge.


The EU Code Week hackathon has three distinct rounds
  1. The 24-hour online hackathon. Out of all those competing, only 12 teams will be chosen to remain in the competition. Free online training and mentoring for all 12 teams, during summer 2021.
  2. The final: the physical hackathon. 10 teams will have all received equal training in the second round, but only one will win. Secondary school students aged 15-19 will compete in teams to solve a ‘local challenge’ selected from proposals submitted ahead of the first round.
  3. Each national winner will face-off in a European clash of titans where each winning team will pitch their solution to a European jury during the official EU Code Week 9-24 October 2021.
In 2021, EU Code Week brings six extraordinary hackathons and invites students aged 15-19 in upper secondary school to form teams and use their coding skills to solve a local challenge. After 24 hours of hacking, each team will pitch their ideas to a panel of experts who will choose the 12 final teams. All teams will have the same amount of time, resources, and access to mentors and expertise in order to complete the challenge, but only 12 will get the chance to continue to the next round, develop their prototype, get expert coaching and take part in the final hackathon in the autumn. In the final the teams will battle it out to decide who wins IT accessories and the chance of mentoring and coaching to further develop their prototype.

Your team is not guaranteed a place in the second round even if you successfully solve the challenge. Remember you are in competition with the other teams and the jury will take your method, use of time and quality of the prototype into consideration to select the successful candidates!

If your team is one of the 12 finalists, you can work on your idea over the summer. To assist you, we will offer you free trainings for development and UX Design. Your team will also get the help of a mentor who ensures that you are on the right path.

The 12 finalist teams will meet in a 12-hour hackathon on the 9 October 2021. Here teams will compete to be the nation’s best young hackers and get the chance to win prizes such as cool IT equipment as well as further coaching and mentoring of their ideas.

Congratulations to all the participants of this first edition of the European Code Week hackathon, it was a real pleasure to have you with us. We hope you had as much fun as we did!

Nikos does not like numbers. Numbers are just a result that is easy to come, if people can overcome the concept of “opposite” and move on to the concept of “together”.
In the last 6 years he is living the dream of his life, applying his whole experience, devoting all his energy and enjoying every minute of the day at Lancom as Chief Commercial Officer.
