The call for challenges of the 5th edition of Ocean Hackathon® is now open. More than 200 challenges are expected. You have a simple idea coming from a need of sea users? You have a more mature project that needs a boost or special expertise? Submit your challenge as a natural person or legal entity in one of the 19 cities organising the event. Once your challenge accepted, participate to the 5th edition of Ocean Hackathon® from 9th to 11th October and perhaps be chosen to represent your city during the international final contest. Ocean Hackathon® is a unique opportunity to experience an idea around the sea by the access to a variety of digital data, the presence of coaches who will help in developping your project, and the motivation of your team members working 48h in a studious but relaxed atmosphere.
