scireum GmbH
scireum GmbH is a Private limited company (Ltd.) registered in Germany under HRB 732171 Stuttgart, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Stuttgart, Germany. 3 shareholders are on record for scireum GmbH, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 17 October 2026.
