Lübke Kelber appoints Dr. Karsten Lieser
Lübke Kelber appoints Dr. Karsten Lieser as new CEO, replacing Marc Sahling in 2026, focusing on leadership transition.

Lübke Kelber AG, a prominent German real estate platform, has announced significant changes to its leadership. Marc Sahling, the company’s Chief Executive Officer, will step down on September 30, 2026, at his own request. This marks the end of his tenure, which began in 2019 and saw him become the sole CEO just last year. His departure comes as the company handles a period of strategic evolution, aiming to solidify its position in the competitive German real estate market.
A Smooth Transition
To ensure a seamless leadership change, Lübke Kelber has appointed Dr. Karsten Lieser to its Executive Board, effective August 24, 2026. Dr. Lieser previously served as Managing Director and Chief Investment Officer of Lübke Kelber Investment Partners, the group’s investment management arm. His appointment reflects the company’s commitment to continuity and strategic growth. By bringing Dr. Lieser onto the board ahead of Sahling’s departure, Lübke Kelber aims to avoid a leadership vacuum and maintain operational stability during the transition.
Jürgen F. Kelber, a member of the Supervisory Board, praised Sahling’s contributions, stating, “Marc Sahling has significantly driven this development and provided important entrepreneurial impulses… We wish him all the best for his future personal and professional path.” Kelber’s remarks show Sahling’s role in shaping the company’s trajectory and highlight the board’s appreciation for his leadership and dedication.
Expanding the Board
What sets this leadership transition apart is Lübke Kelber’s decision to expand its Executive Board. The company has finalized agreements to add another senior executive before the end of the year, though details remain undisclosed. This move suggests the company is positioning itself for growth rather than consolidation. Expanding the board during a CEO transition is a bold strategy, signaling Lübke Kelber’s ambition to enhance its leadership capabilities and drive future expansion. The additional executive is expected to bring fresh perspectives and expertise, further strengthening the company’s governance structure.

By raising a CIO to the board, the company emphasizes its commitment to financial discipline and strategic investment.
A Test of Brand Strength

This consistency is key for maintaining investor confidence and operational momentum during the transition. Lübke Kelber’s brand strength, built on years of excellence and innovation, will be tested as it handles this period of change.
