## About

Arbion traces to a 2009 founding but took its current form in 2022 when Carnegie Smyth and Greg Malone completed the management buyout of Signia, the former investment vehicle of Phones4u founder John Caudwell. The firm operates as a multi-family office advising wealthy entrepreneurs and institutions. Arbion allocates across alternative VC models, commodities, digital assets, direct co-investments, distressed situations, fund-of-funds, hedge funds, infrastructure and private credit. It maintains exposure to early-stage opportunities and targets geographies that include Africa, Asia, Europe and North America. Investment types also encompass AI/ML, consumer tech, enterprise software, ESG, military and Web3 themes. The firm runs three IFSL-branded funds focused on balanced, global and sovereign opportunities. Marco Pabst serves as Group Chief Investment Officer. Robert Lee and Matthew Barnes co-head fixed income and manage the Sovereign Opportunities Fund. No additional offices are disclosed. Arbion's structure stems from the 2022 MBO executed via Holdings29 Limited, separating it from prior single-principal ownership while retaining continuity in mandate and team.
