About

One Stone Global LLC provides investment advisory services primarily to institutional investors and certain high‑net‑worth individuals, including separately managed accounts and corporate pension and profit‑sharing plans. The firm offers asset allocation, creation and implementation of portfolios tied to public or customized indices, sub‑advisor selection and monitoring, and investment product development.

OSG reports $203.9 million of non‑discretionary assets under management and an additional $235.4 million of implementation assets as of December 31, 2024, reflecting a business model that largely emphasizes non‑discretionary and implementation mandates. Its investment approach combines mathematical passive/smart‑beta/enhanced indexation with a quantitative “active tilt” for frontier and African markets, typically implemented through sub‑advisors, ETFs and customized indices.

Compared with many peers, OSG stands out for its concentration on non‑discretionary implementation work and for serving retirement plan clients such as corporate pension and profit‑sharing plans, which are less common for firms in this category. The firm also formally selects and monitors third‑party sub‑advisors and maintains a material commercial relationship with Old Mutual Customised Solutions (Pty) Limited (OMCS), providing and receiving services in a reciprocal arrangement that is uncommon among similar managers.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.

For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
