Art-Invest Real Estate has announced a leadership transition at its Berlin branch. Mathias Groß will join the company’s management board in the first quarter of 2026 and assume responsibility for the Berlin office, succeeding Lena Brühne, who is stepping down after 13 years with the firm to pursue new opportunities in the real estate sector.
Groß will oversee a portfolio of projects in Berlin totalling around 300,000 m² and valued at more than EUR 2 billion. He joins Art-Invest Real Estate from BAUWERT Aktiengesellschaft, where he served as Head of Acquisitions, Project Development and Sales. Prior to that, he spent nine years as Branch Manager at Pandion Real Estate GmbH in Berlin. He is also an honorary board member of Transiträume Berlin e.V. and holds a degree in business administration from the Berlin School of Economics and Law. With more than 25 years of industry experience, he will take over management of one of Art-Invest Real Estate’s key regional operations.
Brühne leaves the company at her own request. Having joined Art-Invest Real Estate in 2012, she initially held roles in North Rhine-Westphalia and Berlin before establishing and leading the Berlin branch from 2016 onwards. Under her management, the location grew into an important part of the organisation, now employing 35 people. Among the projects carried out under her leadership were the Deutsche Bank Campus on Otto-Suhr-Allee, Macherei Berlin-Kreuzberg, and in the eastern region, Listhaus and Dresdner Hof in Leipzig.
“I am very much looking forward to the tasks ahead at Art-Invest Real Estate in Berlin. The current market phase in particular is opening up numerous exciting opportunities. At the same time, our goal is to further develop the existing portfolio in the best possible way. Together with the dynamic Berlin team at Art-Invest Real Estate, I would like to take on this challenge and contribute to the realization of further architecturally outstanding and innovative real estate projects,” said Mathias Groß.
Reflecting on her departure, Brühne stated: “The past 13 years have been characterized by entrepreneurial responsibility and a passion for creating lasting value. From establishing the Berlin office to large-scale projects, we have proven together that strategy and success arise from dialogue with the right people. I would like to thank the entire team for this formative time. As I now turn my attention to new perspectives, I would like to express my special thanks to the shareholders for their trust. I remain on friendly terms with Art-Invest Real Estate.“
Art-Invest Real Estate’s leadership expressed appreciation for her contribution and support for the incoming head of the Berlin office. “We would like to express our sincere thanks to Lena Brühne for her many years of trustful cooperation and wish her all the best for her future. At the same time, we are delighted to welcome Mathias Groß, an expert in the Berlin real estate market, as her successor at the Art-Invest Real Estate Berlin branch and wish him every success in his upcoming tasks,” said Dr. Markus Wiedenmann, CEO, and Dr. Ferdinand Spies, COO of Art-Invest Real Estate Management.
