Cara Investment

Cara Investment was established in 2010 by Petra Orenstein in Frankfurt. The firm manages wealth tied to Stephen Orenstein, a billionaire who previously led Supreme Group. It operates as the single-family office for the Orenstein family while maintaining a professional investment platform. The portfolio spans public equities, fixed income, private equity, hedge funds and real estate. Allocations include middle-market buyouts and growth equity in the US and Europe, global macro and long-short equity strategies, and credit instruments such as cat bonds and AT1s. Real-estate activity covers long-term core holdings and value-add projects executed through joint ventures and mezzanine loans up to $50 million. Confirmed positions include the Bank Building in Washington DC, Zero Bond Street in New York, Q-House in Dublin and multiple logistics and office assets in Frankfurt and Stuttgart. Investments are concentrated in Europe and North America. The firm maintains offices in Frankfurt and London. Team size is not publicly stated. Soren assumed the role of Head of Corporate in 2023 after prior C-level positions in operating companies linked to the group. Philanthropic activity runs through the Cara Foundation, which supports reforestation in Germany, school breakfast programs and marine research at the Senckenberg Institute. Cara Investment differs from typical single-family offices through its hybrid structure that combines internal manager selection with direct real-estate execution and recurring mezzanine financing. This setup allows the firm to retain control over both liquid and illiquid sleeves while partnering with external specialists on a deal-by-deal basis.
