Quantum-Systems OÜ
Quantum-Systems OÜ is a Private limited company (Ltd.) registered in Estonia under 14949989, and its current status with Estonian e-Business Register (ariregister) is active. The company was incorporated on 9 April 2020 and lists its registered address as Tallinn, Estonia. 1 shareholder is on record for Quantum-Systems OÜ, 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 Estonian e-Business Register (ariregister) and was last updated on 7 November 2026.

Officers
2
One of the 2 officer records shown for Quantum-Systems OÜ is a current appointment, filed with Estonian e-Business Register (ariregister). Villiko Nurmoja serves as Juhatuse Liige. The remaining 1 record shown (Marko Kaseleht) is a former appointment that has since been resigned.
Management authority at Quantum-Systems OÜ 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 OÜ sits 1 level below its ultimate parent, Quantum-Systems GmbH, registered in Germany. 1 subsidiary is recorded beneath it, across 2 jurisdictions. Immediately above Quantum-Systems OÜ is Quantum-Systems GmbH, holding 100% as filed in Quantum-Systems OÜ's own shareholder record with Estonian e-Business Register (ariregister). 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 1 subsidiary spans Estonia, United Kingdom 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.
