RSBG SE is the future-oriented, reliable and strong investment partner for innovative and successful medium-sized companies.

By means of strategic shareholdings, we invest in high-growth future markets, sectors and industries that are being shaped by global technology trends and megatrends. This is how we achieve continuous value growth in a diversified investment portfolio that encompasses the following areas:

  • Digitalization solutions, cloud computing, media and communications technology
  • High-tech manufacturing
  • Industrial automation and robot technology
  • Infrastructure and engineering services
  • Pharmaceuticals and life sciences
  • Service robotics

RSBG SE is a wholly-owned subsidiary of the RAG-Stiftung. Our shared roots lie in the coal mining industry. The RAG-Stiftung is a foundation primarily tasked with financing the perpetual obligations left behind by the German hard coal mining industry. Through our equity investments, we make an important financial contribution to the financing of these tasks by the RAG-Stiftung. In this way we contribute to the successful transformation of the former mining regions.


The companies of RSBG SE benefit from the expertise of an experienced partner and investor who specializes in the acquisition, and expansion, internationalization and succession planning of medium-sized companies.
