Arkion Family Office
Arkion Family Office was established in 2001 by chartered accountant Eric Halff. Grégoire Notz joined as co-founder after prior work at the Notz family office. The firm originated from Halff's fiduciary practice and continues to emphasize cross-border structuring for global families. The firm allocates across fund-of-funds, hedge funds, real estate and early-stage startups. It maintains exposure to AI/ML, digital twins and enterprise software. Confirmed holdings include Breitling, QoQa Services, Alpian and Stoneweg. Operations span Europe, Asia, North America, the Middle East and South America. Arkion co-founded ArkGlobe Limited in Hong Kong in 2014 to address the Chinese market. No public headcount or AUM figure is available. The firm established Arkion Group Holding SA in 2021 as its top-level Swiss entity. Additional offices operate in Dubai and Jackson, Wyoming. Arkion principals sit on boards of Stoneweg Hospitality Holding AG and ACE & Company. No operational event from the last 24 months is recorded for the family office itself. Arkion functions as both asset owner and active shareholder in operating companies and funds. This hybrid posture allows direct board influence at portfolio companies while providing traditional family-office services under one regulated Swiss entity authorized by FINMA.
