One of the 4 officer records shown for Boiler Berlin Sauna GmbH is a current appointment, filed with Handelsregister (Commercial Register). Marcel Ketzenberg serves as Geschäftsführer (managing director). The remaining 3 records shown (Guido César and Tim Vogler) are former appointments that have since been resigned.

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.
