## About

Heraeus Holding was founded in 1851 in Hanau, Germany, by Wilhelm Carl Heraeus, a chemist who pioneered the industrial refining of platinum. The firm remains wholly owned by the Heraeus family — now in its sixth generation — and operates as a family office that controls a globally diversified group of technology and materials businesses. The firm's portfolio spans precious metals trading and refining (a major global market-maker in gold and silver), medical technology (dental implants and bone substitution materials via Heraeus Kulzer), industrial catalysts and sensors, and quartz glass used in semiconductor manufacturing. Heraeus also invests in direct businesses focused on additive manufacturing, 3D-printing materials, and renewable energy components. Geographic footprint extends across Europe, North America, Asia, and Latin America, with over 17,000 employees worldwide. Heraeus manages its capital through a single-family-office structure led by CEO Jan Rinnert and a senior management team. The firm has no publicly disclosed AUM or third-party capital, as it allocates the family's wealth entirely. It maintains a separate charitable foundation, the Heraeus Stiftung, which supports science and education. In January 2025, Heraeus announced a partnership with a German university to develop advanced hydrogen-catalyst materials (per company newsroom, January 2025). The structural differentiator for Heraeus is its century-long operational mandate: it is both an industrial conglomerate and a family office, meaning the family's wealth is deployed through wholly owned operating businesses rather than through external portfolio managers. This allows long-cycle investments in materials research and capital-intensive manufacturing that asset managers typically avoid.

## Questions

### Who runs investment decisions at Heraeus Holding?

Investment decisions are made by the Heraeus management board, chaired by CEO Jan Rinnert. The board includes the CFO(Steffen Seemann) and heads of each business division. As a family office, major strategic allocations are also subject to family-shareholder approval (public record).

### Does Heraeus participate in fund commitments or only direct deals?

Heraeus primarily makes direct investments in its wholly owned operating businesses rather than committing to external funds. It has been known to make minority investments in technology startups where strategic fit exists (public record).

### What investment stages does Heraeus typically target?

Heraeus is not a stage-focused investor. Its primary investment vehicle is its operating business portfolio, which spans from early-stage ventures (additive manufacturing, hydrogen catalysts) to mature industrial businesses (precious metals trading, quartz glass).

### Which sectors does Heraeus explicitly avoid?

Heraeus avoids speculative financial assets, pure real estate, and businesses unrelated to its core industrial and technology competencies. It has no disclosed touches on private equity fund management, hedge funds, or pure venture capital.
