Co-production in public administration is essential for increasing societal participation in shaping impactful public policies. This chapter delves into the evolution and impact of the new research and innovation arrangements program (NAPI) in Paraná, Brazil. NAPI, an innovative approach, fosters networks for co-producing knowledge and innovation to address state challenges, rooted in the common principle. At the core of NAPI lies the iAraucária digital platform, harnessing artificial intelligence to streamline resource coordination among stakeholders in regional innovation systems, thereby nurturing research and innovation projects aligned with regional needs. Since its inception, NAPI has spurred the formation of over 60 arrangements, involving more than 4,000 participants in collaborative networks. Noteworthy outcomes include increased precision in research and innovation funding, the cultivation of stronger ties among ecosystem actors, and risk mitigation in public policy co-production, all making substantial contributions to Paraná's sustainable development.
