This paper introduces the RIS Synergy project, an Austrian digitisation project that aims to synergise CRIS Systems across a diverse research landscape. The project brings together various Austrian research institutions and funders to collaborate on the development and implementation of open, standardised interfaces and shared services for research information services. In this paper, we present how the project's bottom up approach proves to provide an effective method to manage system interoperability and information exchange in a multidisciplinary consortium. Furthermore, we offer an insight into RIS Synergy's approach to the conception of an Austrian research portal.
