Hackathons have successfully been run in the last years, getting relevant stakeholders together working on concrete city challenges. From a financial perspective these initiatives have been quite weak, and this needs to be improved. This can be achieved by working on decreasing costs and at the same time increase external funding and support by alternative funding sources and sponsoring. Hackathons also hold a great potential in terms of publicity value which has also the prospective to leveraged. Alternative outputs may also be video material describing targeted challenges etc. justifying part of the cost. We welcome proposals that over time aim for creating increased value and decreased EIT funding needed.
