What Steinbeis does

Steinbeis Holding GmbH is a privately held German family office headquartered in Munich (Joseph-Wild-Str. 13) with a registered seat in Brannenburg, operating as a GmbH under commercial register HRB 6018. The company manages the entrepreneurial assets of the Steinbeis family, a multi-generational industrial lineage with roots traceable to the 19th century in timber, forestry, and paper production, and applies a long-term, no-exit investment mandate focused on sustainability-oriented businesses in environmental technology lead markets.

The portfolio is organised around three business areas — circular economy, green energy, and ecological paper production — executed through wholly-owned operating subsidiaries. Key holdings include Steinbeis Papier GmbH (described as Europe's most advanced ecologically integrated recycled paper mill), EBS Concept (low-carbon substitute fuels from municipal and commercial waste), AP Concept (waste paper disposal and processing), Steinbeis Polyvert (high-quality plastic recyclates), Steinbeis Neue Energie GmbH/ST-UEN (combined heat and power), Biomasseheizkraftwerk Papenburg (carbon-free biomass electricity), and four solar and wind installations totalling approximately 23 MW across Bavaria, Rhineland-Palatinate, and Baden-Wuerttemberg.

The business model is that of a patient-capital family office: Steinbeis Holding provides equity, equity-equivalent instruments, and subordinated loans to mid-market SMEs and earns continuous income from participations alongside sustainable value appreciation, without pursuit of liquidity events. Distribution is conducted via direct investment engagement rather than external channels, and the holding leverages brand association with the separately incorporated Steinbeis Foundation (founded 1971) and Steinbeis GmbH & Co. KG für Technologietransfer (founded 1998) for knowledge and technology transfer resources, while remaining operationally independent from those entities.
