Codesphere is a Virtual Cloud Provider from Germany building the future of sovereign cloud infrastructure. Our platform gives enterprises and governments full sovereignty without giving up modern cloud capability – a vision recently validated by a series of multi-million European government tenders.
Since our founding in Karlsruhe in 2020, we’ve expanded into an international team of 60+ experts. Based in Karlsruhe and Munich and backed by top-tier investors, we are chasing a bold vision.
