Officers
5
Three of the 5 officer records shown for joint-tec GmbH are current appointments, filed with Handelsregister (Commercial Register). Martin Oeser (appointed 2019-04-08) serves as Geschäftsführer (managing director); Josephine Herzig (appointed 2011-03-04) and Jirka Heiser (appointed 2020-07-15) both serve as Officer. The remaining 2 records shown (Ellen Überall and Matthias Herzig) are former appointments that have since been resigned.
Management authority at joint-tec 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
joint-tec GmbH sits 3 levels below its ultimate parent, AT Beteiligungs GmbH & Co. KG, registered in Germany. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above joint-tec GmbH is OAT Beteiligungs GmbH, holding 27.3% as filed in joint-tec GmbH's own shareholder record with Handelsregister (Commercial Register). AT Beteiligungs GmbH & Co. KG sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. 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 Germany jurisdiction, 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.
