The Oeri family, through SANOSTRO, manages wealth originating from one of Europe's largest healthcare fortunes. The firm is headquartered in Switzerland and does not publicly disclose its investment team or AUM. The investment strategy of SANOSTRO AG is understood to span public equities, fixed income, real estate, and private equity, consistent with the diversification typical of large European family offices. The firm is believed to make direct co-investments alongside external managers and participate in fund commitments. Geographic focus appears to be global, with a European and North American lean. SANOSTRO's team size and professional composition are not publicly detailed, adding to its reputation for discretion. The firm maintains no known philanthropic or operating-company vehicles that have been separately disclosed.

Frequently asked questions
Who runs investment decisions at SANOSTRO AG?
SANOSTRO AG does not publicly disclose its investment leadership or professional team. As a Swiss single-family office for the Oeri family, key personnel are private. The firm likely employs a board or investment committee with family representation and external advisors, but no names have been made public.
Is SANOSTRO AG a single family office or does it operate more like a multi-family office?
SANOSTRO AG operates as a single-family office, primarily managing capital for the Oeri family branch of the Roche founding family. It does not appear to serve external families or institutional clients, typical of Swiss SFOs focused on wealth preservation.
What investment stages does SANOSTRO typically target?
Based on limited public data, SANOSTRO AG likely operates across a broad multi-asset mandate, including public equities, fixed income, real estate, and private equity. It probably makes direct co-investments in private companies and fund commitments, favoring later-stage and mature assets over early-stage venture capital.
Does SANOSTRO participate in fund commitments or only direct deals?
SANOSTRO AG is expected to engage in both fund commitments and direct investments, a common structure for large European family offices. The firm likely commits capital to external private equity and real estate funds while also pursuing direct co-investments alongside trusted partners. Public records of specific commitments are unavailable.
Where does the underlying wealth for SANOSTRO come from?
The wealth managed by SANOSTRO AG originates from the Oeri family's stake in Roche Holding AG, the Swiss pharmaceutical giant founded by Fritz Hoffmann-La Roche in 1896. The family's fortune is among the largest in Europe, built on the company's blockbuster drugs and diagnostics.
How is SANOSTRO related to other family offices linked to the Roche founding family?
SANOSTRO AG is specifically tied to the Oeri branch of the Hoffmann-Oeri family. Other branches, like the Hoffman family, maintain separate structures (e.g., Hoffman Family Office). SANOSTRO functions independently, managing the Oeri share of the Roche fortune, and is not known to co-invest with sibling family offices.
Does SANOSTRO maintain philanthropic structures, and how are they separated?
SANOSTRO AG's primary vehicle is the family office. The Oeri family also supports philanthropic initiatives through separate foundations, such as the Oeri Foundation, though these are distinct from the investment office. SANOSTRO focuses on asset management and wealth preservation, not grant-making.
