If you have open data, or an idea of how a dataset could advance science or education, propose a challenge. Your organization gains visibility among young talent across Latin America, receives different approaches to a solution and joins the jury for its challenge. Data must be openly accessible. Challenges are selected for relevance, impact, originality, technical feasibility and clarity. Proposers are expected to participate during the hackathon.
Propose a challengeUnsure whether your idea would make a good challenge? Ask on Discord before filling in the form.
Open to enrolled university students living in Latin America, at undergraduate, master’s or doctoral level, in any discipline. You do not need a team beforehand: registration is individual and multidisciplinary teams form at the start of the event. A support fund is available for connectivity, expenses or other barriers to participation; apply through the same registration form. There will be prizes.
