## About

Hassium Asset Management was established in 2006 by Yogesh Dewan. The firm began by serving two entrepreneurial families and has since broadened its client base to additional high-net-worth households. Dewan previously spent ten years at Goldman Sachs advising wealthy clients. The firm deploys capital through private equity, fund-of-funds vehicles, direct co-investments and hedge fund allocations. Confirmed geographic exposure covers Europe, North America and Africa. Investment stages include early-stage opportunities, with sector emphasis on AgriTech & FoodTech alongside indicated activity in FinTech and Digital Health. No specific portfolio company names appear in public records. Team size and additional office locations remain undisclosed. In October 2025 Turicum Private Bank, a Gibraltar-based institution, acquired a majority stake in the firm, establishing a UK footprint. The transaction was reported across multiple wealth-management publications that month. Hassium maintains a direct-deal capability alongside fund commitments and operates a philanthropic allocation sleeve. Governance now reflects the influence of its new majority owner while preserving the original discretionary mandate structure for client families.
