Michael Mei serves as Geschäftsführer (managing director); Marc Fischer (appointed 2005-04-20), Ida Zsuzsanna Kozma (appointed 2016-03-08) and Ulrike Wien (appointed 2022-05-06) all serve as Officer.

The register reports 7 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Menlo 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
Menlo Systems GmbH has no recorded parent company — it sits at the top of its own group structure, with 3 subsidiaries recorded beneath it across 3 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 3 subsidiaries span Germany, China, United States 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.
