About this opportunity
The PESOSE programme funds organisations that are building sustainable, secure open-source ecosystems around research software, hardware, AI models, datasets, and digital infrastructure. Rather than funding individual software projects alone, the programme supports long-term governance, community building, cybersecurity improvements, and translation of research outputs into widely adopted open-source technologies.
