A hackathon is a 48 hours pressure cooker where teams built solutions to the challenges brought by the launching customers/ sponsors. The hackathon is also a competition between the teams with a chance to win a cumulative €200.000 cash reward.

A track is a focus topic brought up by a partner, which we also refer to as launching customer. Within one track there could be one or more challenges that the partner would like the teams to bring solutions to. Please check the different 2019 challenges here <link to the tracks overview>.

The hackathon is optimized for pre-startups, startups, small businesses and corporate teams with an innovative solution for the outlined challenges. Only team captain with a full team of 5 to 6 people can apply on behalf of the team.

Join our online community, where you can invite people to join your team or show interest to be part of an existing team. The platform is also a great way to ask questions to the challenge-owners and sign up for the upcoming Deep Dives.

Every team needs to have 5-6 members with a diverse set of skills.

Important: make sure your team consists of people that can quickly adapt to change, as during our hackathon you will be experiencing time pressure in a dynamic environment.

front-end developer
back-end developer
UX/ UI designer
Business/ enterprise/ software architect

Business or marketing expert

  1. All team captains have to fill in an application form covering all team roles, clear motivation, great ideas, and plans to incubate and accelerate the solution after the Hackathon.
  2. Odyssey team will curate the applications and invite the captains of best applications for an interview call.
  3. After the interview phase, Odyssey team will select the top 100 teams based on the team’s motivation, ambition, and expertise.

Participation is free. You have to arrange your own travel & accommodation.

The IP of the work that is produced throughout the hackathon belongs to the team ONLY IF the challenge holder does not mention that the codes should be open source. Check carefully the conditions of each challenge beforehand.
