Public sources do not give a career history for the angel investor in the QuTwo round. Press coverage of QuTwo names him without a biography or employer. This profile therefore makes no claim about companies he founded or ran.
The name is shared with the businessman who owns the Schwarz Gruppe, the parent of Lidl and Kaufland. Nothing we found confirms that this angel is the same person, and we have not assumed it.
The only public angel investment we could confirm is QuTwo. Crunchbase lists one personal investment for a Dieter Schwarzmann, in an angel round at QuTwo, and shows the round as announced on May 5, 2026. It is unclear whether that listing is the same person. Other public details of his angel activity, such as other deals or years active, are not available.
QuTwo is a Finnish AI lab founded by Peter Sarlin. Dealroom reports a €25M pre-seed round that was its first external funding, at a valuation of roughly $380M. TechCrunch lists Dieter Schwarz among the angels in the round, alongside Yuri Milner, Xavier Niel, Nico Rosberg and Niklas Zennström, and founders from companies including Miro, Skype, Supercell and Wolt.
QuTwo's main product is QuTwo OS, an orchestration layer that routes tasks to classical, quantum or hybrid computing architectures. It targets enterprise use cases. The Lounge deals desk records this round as pre-seed, 2026-06.
Public information is too thin to describe a thesis. The one confirmed deal is a pre-seed AI company based in Finland, with enterprise customers. He has made no public statements about what he looks for, and no check size is public. We have left both out rather than guess.
