Project Stage:Development / validation / demonstration: applicants should propose solutions that can be designed, developed, integrated with ODEON components, and validated with users within the programme timeline.
Consortium Requirement and Co-funding
Consortium:Single legal entity applications are expected (the call funds individual third parties). The Open Call targets individual suppliers or users; consortia are not the primary model. Co-funding: funding is granted as a lump sum up to €60,000 per selected project. The Open Call Terms and Conditions and SubGrant Agreement Template specify whether additional co-funding or co-investment is required; applicants should consult the Terms and Conditions for any mandatory co-financing or matching requirements.
Co-funding Requirement:Lump-sum award up to €60,000. Applicants should review the SubGrant Agreement Template for exact financial and reporting obligations.
