KLAR Partners becomes the new majority shareholder of the KONZMANN Group — a rapidly growing platform in the energy and building services engineering sector
The KONZMANN Group is one of Germany’s leading mid-sized providers of energy and building technology and has evolved into a rapidly growing platform in recent years. With the support of KLAR Partners (“KLAR”), the KONZMANN Group will further strengthen its position as a trusted partner and attractive employer in the industry and continue to drive its long-term growth in the German market in a targeted manner.
In recent years, the KONZMANN Group has continued to evolve. Strategic acquisitions, the ongoing optimization of existing business processes, and a corporate culture firmly established from the very beginning form the foundation of this success story. Despite its size, the group continues to be characterized by independently operating, regionally rooted subsidiaries that preserve their individual historical identities and market presence. This concept has proven to be extremely successful. In the 2024 fiscal year, the group achieved total revenue of approximately 180 million euros.
With approximately 1,100 employees across 21 companies, the KONZMANN Group today offers a comprehensive 360° portfolio of services: ranging from core building services engineering competencies such as heating, air conditioning, ventilation, and plumbing to refrigeration and electrical engineering, and building automation. The offering is complemented by consulting, planning, and design services, as well as comprehensive maintenance and repair services. In this way, the group supports private, commercial, and public customers alike on their path toward an energy-efficient, environmentally friendly, and economically sustainable future.
Oliver Rennig, CEO of the KONZMANN Group, emphasizes in this context: “Special thanks go to Adiuva Capital. Together, we have significantly advanced the KONZMANN Group in recent years while successfully preserving our corporate culture. With Adiuva Capital as our partner, we have been able to shape the KONZMANN Group into a remarkable corporate group while simultaneously laying the groundwork for today’s growth. We are very grateful for this.” He continues: “I would also like to extend my special thanks to Georg Jacobi and Arne Doll for their consistently trusting and successful collaboration.”
With this formal change in ownership, Adiuva Capital is now passing the baton to KLAR Partners. Both parties share a commitment to enabling sustainable growth and securing value over the long term.
The choice of KLAR as the new partner was a deliberate one: it is not only KLAR’s international industry expertise that makes the company an ideal partner on the path to further growth. Above all, KLAR’s values-driven corporate culture mirrors the DNA of the KONZMANN Group a good “match” that forms the basis for a trusting partnership focused on security and sustainability.
“With KLAR by our side, we have the best conditions to consistently build on our strengths and tap into new growth opportunities in the German market,” said Oliver Rennig. “I am particularly pleased that we have not only gained a strong, reliable partner, but rather an ally who shares and lives our values-driven corporate culture. This partnership marks a decisive step toward our vision of becoming one of the leading providers of energy and building technology in Germany.”
KLAR is also confident: “The KONZMANN Group fits perfectly into our acquisition strategy. It is a dynamic company focused on future growth, offering a broad portfolio of services and distinguished by its strong local roots,” says Felix Abercron of KLAR. “We look forward to actively supporting the KONZMANN Group in the next phase of its development.”
The transaction is still subject to the usual regulatory approvals.
