Cube 5 supports cybersecurity spin-offs from Horst Görtz Institute for IT-Security at Ruhr-University Bochum and fosters new business models. A special feature is the entrepreneurship education program for it-security students. Professional help is given to the teams by technology and business experts within the Cube 5 partner network. We furthermore provide work places. The project is sponsored by the German Federal Ministry of Education and Research (BMBF).
