Konzmann Gmbh

What Konzmann Gmbh does

Konzmann GmbH (operating as KONZMANN Gruppe) is a German technical building equipment (TGA – Technische Gebäudeausrüstung) platform headquartered in Friedrichshafen, with roots dating to 1921. The group delivers a 360-degree TGA portfolio spanning eight technical disciplines — heating, air conditioning, ventilation, sanitary, refrigeration, electrical engineering, measurement/control/regulation (MSR) building automation, and media supply — complemented by five service pillars: consulting and conception, planning with BIM, energy-related services, technical operations, and maintenance. Project execution is supported by Building Information Modeling (BIM) across HOAI service phases 1–9, enabling coordinated planning of multi-trade installations for commercial, industrial, public-sector, and private customers.

The group operates through 21 independently operating, regionally rooted subsidiaries across Germany that retain their individual identities and customer relationships while leveraging group-wide purchasing, brand, and technical resources. Approximately 1,100 employees serve customers in healthcare, food processing, manufacturing, hospitality, education, and senior living. Revenue is generated through project-based installation work, recurring maintenance and service contracts (including 24/7 emergency service), engineering and consulting fees under HOAI, and energy-efficiency services. Customer logos include Heidelberg University (Center for Organismal Studies), Wild Kartoffelverarbeitung, Gebr. Schwarz, MENetatis Seniorenwohn- und Pflegeheim, Studierendenwerk Karlsruhe, COLDIS Deutschland, and Jetter Firmengruppe, indicating mid-sized, diversified exposure.

Ownership transitioned in October 2025 when KLAR Partners, an investment firm focused on building services and energy efficiency, completed its acquisition of the majority stake from previous sponsor Adiuva Capital. The group has continued an active buy-and-build program, with recent acquisitions including Ingenieurbüro Brundobler (February 2026), Herber & Petzel Gebäudetechnik (March 2026), Weber Haustechnik and Ingenieurbüro Koppe (2025), HAUSCONSULT (2023), and HSV Gebäude- und Klimatechnik (2022). A new CFO was appointed in March 2026, alongside dedicated M&A and post-merger integration staffing, supporting ongoing platform expansion.
