This document presents an overview of the collaboration activities undertaken by BBioNets with other EU-funded projects and initiatives. It outlines the strategic approach used to identify and engage with relevant projects, and the series of activities performed to reach its targets. Since the early stages of the project, collaboration has always been a core component of the BBioNets strategy, designed to leverage synergies, foster knowledge exchange across related projects and, thus, maximise their overall impact. The process of identifying relevant projects began during the preparation phase of the BBioNets “D4.1 - Plan for Dissemination and Exploitation including Communication activities”, when all consortium partners provided information on initiatives they considered relevant to the project’s scope and objectives. It was further pursued by conducting a thorough search in the EU Funding & Tenders Portal and recent Work Programmes to discern potentially relevant topics and successful proposals across various destinations. All pertinent information was collected in an excel file to facilitate project selection based on carefully determined selection criteria. Over the first reporting period, BBioNets established partnerships with 29 individual projects and 5 platforms/networks clustering more than 50 projects in total. Its activities focused on joint communication and dissemination, information and data sharing, and co-organisation of events. BBioNets’ key achievements include the alignment of dissemination efforts through coordinated social media campaigns, contribution to and promotion of each other’s newsletters and significant activities, attendance at joint meetings or events, the organisation of several joint workshops, cross-referencing in publications, and involvement or assistance in specific activities. These collaborative actions have contributed significantly to increasing the visibility and reach of both BBioNets and its partner projects, paving the way for a broader uptake of project outcomes. Overall, the results demonstrate the added value of inter-project collaboration in amplifying the impact of EU funding in research and innovation.
