MBB SE
MBB SE is a registered legal entity registered in Germany under HRB 165458 B Charlottenburg (Berlin), and its current status with Handelsregister (Commercial Register) is active. The company was incorporated on 9 March 2015 and lists its registered address as Berlin, Germany. 5 shareholders are on record for MBB SE, 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 25 September 2026.

Shareholders of MBB SE
Five shareholders are currently on record for MBB SE, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG.

Directors and officers of MBB SE
Two of the 22 officer records shown for MBB SE are current appointments, filed with Handelsregister (Commercial Register). Jakob Ammer serves as Managing Director; Constantin Mang (appointed 2018-07-18) serves as Owner. The remaining 17 records shown (Christof Nesemeier Ph.d., Constantin Mang Ph.d. and 12 others) are former appointments that have since been resigned. Management authority at MBB SE 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
Group structure of MBB SE
MBB SE has no recorded parent company — it sits at the top of its own group structure, with 4 subsidiaries recorded beneath it across 2 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.
- DTS IT AG (Germany)
- HANKE TISSUE SP Z O O (Poland)
- CT Formpolster GmbH (Germany)
- Delignit AG (Germany)
Data availability
Those 4 subsidiaries span Germany, 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. Two of the 4 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
