The Quandt family ranks among Germany’s wealthiest families, with approximately $40 billion in collective wealth derived primarily from their controlling stake in BMW Group. Susanne Klatten and Stefan Quandt, the children of Herbert Quandt, together own approximately 47% of BMW, one of the world’s most valuable automotive manufacturers. Herbert Quandt is credited with saving BMW from near-bankruptcy in 1959 by investing the family’s capital when other shareholders were prepared to sell to Daimler-Benz.
Investment Strategy
The Quandt family’s investment strategy extends well beyond their BMW anchor holding. Both Susanne Klatten and Stefan Quandt have built substantial independent investment portfolios through separate holding companies, diversifying into chemicals, technology, industrial services, and financial assets.
Susanne Klatten is one of the most active investors in the Quandt family. Beyond her BMW stake, she holds approximately 50% of Altana AG, a specialty chemicals company that generates over $3 billion in annual revenue. Her investment firm, SKION, manages a diversified portfolio that includes direct investments in technology companies, renewable energy, and German Mittelstand businesses. SKION has invested in companies across biotechnology, fintech, and mobility, reflecting Klatten’s interest in innovation and industrial transformation.
Stefan Quandt manages his investments through Delton AG, a holding company based in Bad Homburg. Delton’s portfolio includes logistics companies, industrial services, and technology investments. Stefan’s approach tends toward traditional German industrial investments, with long holding periods and a focus on operational excellence in core businesses.
Both siblings sit on BMW’s supervisory board and are actively involved in the company’s strategic direction, including its transition to electric mobility. The family’s commitment to BMW is not passive shareholding; the Quandts view themselves as stewards of one of Germany’s most important industrial companies and take an engaged approach to governance.
Private Markets Approach
The Quandt family’s private markets activity reflects the German family office tradition of building and holding industrial businesses over multiple generations. Susanne Klatten’s SKION has been particularly active in growth equity and venture capital, investing in German and European technology companies at the growth stage.
SKION’s investment areas include renewable energy, digital health, advanced materials, and mobility technology. Klatten has positioned SKION as a bridge between traditional German industry and the emerging technology ecosystem, providing capital and industrial expertise to companies that are transforming established sectors.
Stefan Quandt’s Delton AG focuses on direct ownership of operating businesses, including Logwin (international logistics) and various industrial service companies. Delton operates with a buy-and-hold philosophy, building long-term value through operational improvement rather than financial engineering.
Both family members have also invested in real estate, though these holdings are modest relative to their industrial portfolios. The family maintains properties in Bavaria, Hessen, and other German regions.
The Quandt family’s philanthropic activities include the Herbert Quandt Foundation, which supports education, intercultural dialogue, and social responsibility initiatives. The foundation reflects the family’s broader commitment to responsible ownership and the German stakeholder model of corporate governance, which balances shareholder returns with employee welfare, environmental responsibility, and community engagement.
