You own an exciting company
in the building services sector?
We offer you succession solutions and security for the future of your company!
Many entrepreneurs in the building services sector face the challenge of entrusting their life’s work to trusted hands—whether due to age or the lack of an internal family successor. Here, the KONZMANN Group offers you the opportunity for a stable, value-oriented handover to a corporate group that takes responsibility seriously.
The regulation of business succession is one of the biggest challenges faced by owner-managed companies in the building services sector. The lack of successors not only jeopardizes the future of the company but also the security of employees, customers, and business partners.
A professional succession solution preserves what has been built — while simultaneously creating new perspectives: for the company, the team, and sustainable further development. Within this framework, the KONZMANN Group always aims for 100% ownership to ensure a stable and future-proof integration.
Let us work together to find a solution that secures continuity, maintains stability, and opens up new opportunities.
Our expression of interest is directed at the following companies in the building services sector:
- Entrepreneurs without internal family succession
- Business owners approaching retirement
- Managers wishing to withdraw from operational responsibility
- Small to medium-sized enterprises with high-quality standards
