What PAT Holding does

PAT Holding (P.A.T. Holding GmbH) is a German privately-held industrial services group headquartered in Kirchheim unter Teck that specializes in process and plant engineering for power plants and waste incineration (Müllverbrennung) facilities. Founded in 2011 as P.A.T. GmbH by Herbert Appl and Jan Volgmann, the holding structure was established in 2021 to consolidate the operating subsidiary and partner companies under one entity. Today the group is led by co-founder Jan Volgmann (Geschäftsführer) and commercial managing director Robert Krestka, who succeeded founding MD Appl in 2021. The company employs 51–100 staff and operates from four German locations (Kirchheim unter Teck HQ, Bremerhaven, Willich/Düsseldorf, and a Leipzig/Central Germany branch).
