Susanne Klatten

Overview

Susanne Klatten is one of Germany's most consequential industrial shareholders and one of the leading figures in the country's family-office capital ecosystem. She is a co-controlling shareholder of BMW AG through Susanne Klatten Beteiligungs GmbH, the sole owner of specialty-chemicals group Altana AG through SKion GmbH, and the founder and Chairwoman of the Supervisory Board of UnternehmerTUM, one of Europe's leading entrepreneurship and deep-tech centres. She serves on the BMW Supervisory Board (since 1997) and on the BMW Nomination Committee (since 2024), and as Managing Director of SKion GmbH she leads the family office that anchors her industrial and technology portfolio.

Why this entity matters

Susanne Klatten belongs in the Startuprad.io knowledge graph for three converging reasons. First, her SKion GmbH is one of Europe's most influential evergreen family-office capital vehicles and a recurring reference point in Startuprad.io coverage of DACH capital structure, industrial ownership and long-horizon investing. Second, she is the founder of UnternehmerTUM, whose alumni base includes Celonis, Flix, Isar Aerospace and Konux and which is a structural pillar of Munich's deep-tech ecosystem covered across Startuprad.io. Third, her ownership positions in BMW and Altana place her at the intersection of the German automotive and specialty-chemicals sectors that recur in Startuprad.io analysis of DACH industrial capital.

Career, company, or institutional background

Klatten holds a B.Sc. in Business Studies from the University of Buckingham (1985) and an MBA from IMD Business School in Lausanne (1988). Her early career included stints at Young & Rubicam in Frankfurt, Dresdner Bank in London, McKinsey & Company in Munich, Bankhaus Reuschel, and a management-assistant role at Hubert Burda Media. From roughly 1988 to 1989 she completed an incognito traineeship at the BMW plant in Regensburg. She joined the Altana AG Supervisory Board in 1993 and the BMW AG Supervisory Board in 1997. In 2002 she founded UnternehmerTUM with a roughly ten-million-euro endowment, in 2006 she founded SKion GmbH as her primary industrial and technology investment vehicle, and between 2008 and 2010 SKion took Altana fully private via tender offers. From 2013 to 2023 she chaired the Supervisory Board of SGL Carbon. In June 2024 she transferred more than 99% of SKion GmbH ownership to the next generation of the family while remaining Managing Director; the transfer was confirmed to BaFin via an SGL Carbon voting-rights notification on 25 June 2024. She was re-elected to the BMW Supervisory Board in May 2024 (term to 2028) and joined the Nomination Committee that year.

Role in the startup, technology, investment, or innovation ecosystem

Klatten's ecosystem footprint centres on UnternehmerTUM and SKion. UnternehmerTUM, affiliated with the Technical University of Munich, supports more than 100 high-growth startups annually and, together with its affiliated venture fund UVC Partners (more than 300 million euros in AUM), forms the institutional core of Munich's deep-tech ecosystem. SKion GmbH is the anchor of her industrial and technology portfolio, with holdings across Altana AG's four divisions (BYK, ECKART, ELANTAS, ACTEGA), SGL Carbon (largest shareholder at 28.55%), Entrust Inc. (approximately 40%), and the SKion Water platform (Ovivo, EnviroChemie, Paques, ADASA, Enpure, Sanpure, Malmberg, ENWA, FIDO Tech, Inuwat). In 2018 SKion and Altana jointly invested in Landa Digital Printing (exited 2025 to FIMI Opportunity Funds); in 2022 SKion acquired a 20% stake in BMZ Group and took sole ownership of the restructured business in February 2026. Nordex SE was fully exited by 2026. Altana revenue reached 3.17 billion euros in 2024.

Wealth estimates (dated, point-in-time)

In manager magazin's 2026 ranking of the 500 richest Germans, Susanne Klatten and her brother Stefan Quandt are listed jointly in fourth place with an estimated combined fortune of about 33.3 billion euros, down from 36.1 billion euros a year earlier (a decline of about 2.8 billion euros). Listed holdings were valued at closing prices on 15 September 2026. manager magazin publishes no separate figure for Klatten, so the 33.3 billion euros is a joint estimate, not her individual net worth. The estimate moves largely with the BMW share price and is recorded here as a dated observation, not a fixed attribute.

As a co-donor with her brother Stefan Quandt she committed to the 2016 recapitalisation of the BMW Foundation Herbert Quandt and later to Stiftung Charité. Through the Quandt-family ownership structure of BMW she and Stefan Quandt together control the largest voting bloc in the company. She is a Honorary Senator of the Technical University of Munich since 2004 and served on the University Council from 2005.
