The businessman Petr Němec, whose development company Sebre built the DRN office building has become a shareholder in Nano Energies, a tenant in that building. He joins an elite group of shareholders, having acquired a 37.5 percent share together with Petr Zahradník, who’s involved in companies such as Qminers and Iterait. Hospodářské noviny reports that Nano Energies founder Petr Rokůsek also has a 37.5 percent share, while Tomáš Janeček (brother of the billionaire co-founder of the RSJ financial group) holds a 25 percent stake. “It was the technological quality of the solution that convinced me,” he told HN. “We’re going to invest systematically into the development of existing platforms, people and development – that’s how we’ll add further quality to energy and through that into our lives or the environment in which we live,” said Němec.
