Adiuva Capital has entered into an agreement to sell the KONZMANN Group to KLAR Partners. Funds advised by KLAR Partners Ltd. have agreed to acquire the KONZMANN GmbH, one of Germany’s leading providers of technical building services. Completion of the transaction remains subject to the ongoing antitrust review.
The KONZMANN Group employs around 1,100 people at over 30 sites, making it one of the largest providers of technical building equipment in Germany. The range of services includes a complete portfolio of energy and building technology, including heating, air conditioning, ventilation, sanitation, refrigeration and electrical engineering, as well as planning, consulting and energy-related services. In 2024, the Group generated a total output of around 180 million euros.

Adiuva Capital invested in KONZMANN in 2016 as part of a succession arrangement and supported the management team in the company’s transformation and institutionalisation. Starting from its original business area in the Black Forest region, KONZMANN first expanded throughout southern Germany and subsequently nationwide. More than 20 companies have since joined the KONZMANN Group and arranged their succession within the Group.
“We are very proud to have supported the KONZMANN Group in implementing its buy-and-build strategy and to have successfully executed numerous succession solutions together with the management team. Our sincere thanks go to the leadership team under Oliver Rennig for their trusted and collaborative partnership,” said Georg Jacobi, Partner at Adiuva Capital.
Oliver Rennig, Managing Director of the KONZMANN GmbH, added: “Adiuva Capital has been a reliable partner, consistently supporting us on our growth path over the past years. I would like to express my sincere thanks for the close, constructive and, above all, personal cooperation, as well as for the trust placed in us.”
