Turnstone Group
Turnstone Group was established as a multi-family office in the Isle of Man. It supplies wealth-management, investment-advisory, and fiduciary services to families that hold complex international assets. The firm allocates across distressed and turnaround situations, private credit, real estate, and secondaries. It also covers buyout and growth stages and maintains exposure in Africa, Europe, and North America. Confirmed sector focuses include PropTech and supply-chain logistics. No public data exist on team size, additional offices, or vehicles launched in the last 24 months. The firm publishes no AUM figure. Turnstone separates its investment mandates from its family-governance and succession-planning work, allowing clients to maintain distinct structures for operating companies, trusts, and foundations.
