Sonion
Sonion is the family office of the founders of Sonion A/S, a Danish manufacturer of miniature components for hearing aids and other acoustic devices. The firm was established after the family divested their industrial holdings, with the office now structured to manage and grow the family's wealth through diversified investments. The family office allocates capital across real estate, infrastructure, private credit, and healthcare services, with a stated focus on direct investments and co-investments alongside institutional partners. Geographically, Sonion invests in North America, Europe, and the Middle East. Notable portfolio exposures have included commercial real estate in the US and infrastructure projects in Europe, though specific transaction details are not publicly disclosed. Sonion maintains offices in Chevy Chase (Maryland), Dubai (UAE), and Roskilde (Denmark). The firm does not publicly disclose its team size or AUM. It operates as a single-family office, with no known adjacent philanthropic foundations or operating companies disclosed separately. In late 2023, the firm was reported to have increased its allocation to direct private credit investments in the US mid-market. The office's structural differentiator is its evolved geography: rather than operating solely from a single European or US hub, Sonion maintains a tri-continental presence that allows it to source and manage investments across the US, Europe, and the Middle East — a spread uncommon among single-family offices of its size and origin.
