Quantum-Systems GmbH
Quantum-Systems GmbH is a Private limited company (Ltd.) registered in Germany under HRB 217004 München, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Gilching, Germany. 5 shareholders are on record for Quantum-Systems 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.

Shareholders
5
Five shareholders are currently on record for Quantum-Systems GmbH, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG.
The largest of these is Quantum Founder Holding UG (haftungsbeschränkt), holding 12.3% — the largest recorded stake — followed by Quantum Founder Holding UG (haftungsbeschränkt) at 10.7%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 55 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Geschäftsführer (managing director) of Quantum-Systems GmbH currently on record is Florian Seibel; five officers are currently on record for Quantum-Systems GmbH, filed with Handelsregister (Commercial Register).
The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Quantum-Systems GmbH sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Quantum-Systems GmbH has no recorded parent company — it sits at the top of its own group structure, with 19 subsidiaries recorded beneath it across 6 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 19 subsidiaries span Germany, Lithuania, Australia, Estonia, United Kingdom, Poland jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 19 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
