WP1 developed the SRMS and a list of 26 socially responsible indicators for investment in STEM start-ups. We applied (RRI), lean start-up approach (LSA) and Quadruple Helix (QH) principles to the context of start-ups; this led to the definition of the contextualized RRI model for STEM startups and impact investment based on a processual model of 4-helix collaborations, including the RRIstart indicators, and the common methodology to implement RRI model for impact investment in STEM. WP2 developed the Social Lab-based pilot methodology executed within the 3 pilots, namely, the Social Lab-based methodology for pilots and the template for assisting Social Lab facilitators. The 3 pilots researched on the feasibility and effectiveness of the SRSM by testing its ability to institutionalise RI in early-stage STEM start-ups, and to guide impact investment. WP3 set up the necessary tools so that the SRSM could be applied by STEM start-ups and investors and to create a facilitating support network. It also released Guidelines on Governance Settings for the adoption of a responsible approach by STEM Start-ups, Recommendations for Investors on the use of the SRSM, the Exploitation Business Plan. WP4 focused on the release of the Communication, Dissemination and Training Plan, and: a) promoted the project and its results through all communication channels, b) delivered the training workshops produced which included a theoretical introduction to the SRSM and hands-on learning activities, c) submitted academic papers based on project results for review and publication, d) organised and delivered the final project conference in Rome, which included workshops and a hackathon developed with major industrial actors. WP5 ensured the implementation of the activities by proposing the internal Quality Plan, the DMP, setting up the AB and communication with it, arranging face-to-face and virtual meetings between the consortium partners (8 project general meetings, and overviewed the organisation of other 37 development meetings in the other WPs), and the official project reporting towards the EC.WP6 studied and defined the ethics requirements for the project. The main delivered result describes the procedures for obtaining ethical approval for human participation in project activities, the use of informed consent, and the anonymization procedures that have been put in place.
