Hamburg, 9 November 2026 - RSM Ebner Stolz has supported INVISION VII, a fund advised by INVISION AG, with a financial due diligence in the acquisition of a majority stake in the aTmos Group.

Headquartered in Riedstadt (Hesse), the aTmos Group is a leading provider of planning and execution of complex refurbishment and maintenance projects for commercially and industrially used roof areas and building envelopes. With around 90 employees, aTmos handles complex projects across the DACH region. A particular focus is on technically demanding projects in which ongoing operations must be maintained during refurbishment. Its services range from planning and project design through project management to subsequent maintenance and servicing by its own service technicians.

Since its founding in 1997, INVISION has developed into one of the leading investment firms in the mid-market segment, focusing on companies in the DACH region and the Benelux countries. INVISION has invested more than one billion euros in over 80 companies and pursues sustainable growth through internationalisation, the introduction of new products and services, the digitalisation of business processes and targeted add-on acquisitions. INVISION sees itself as an entrepreneurial partner for founders and management teams.

Together with the existing management team, INVISION intends to further expand aTmos’ market position and drive growth both organically and through targeted acquisitions. The focus is in particular on geographic expansion, growing the maintenance business and the targeted extension of the service portfolio around the current core business.
