Partners Capital Management

Day-to-day investment leadership is led by Chief Investment Officer William McChesney, who joined in 2006. The investment committee, chaired by McChesney, oversees asset allocation and manager selection. CEO Jeremy Simpson, promoted in March 2025, handles firm strategy and operations (per the firm, 2025).

Partners Capital is an outsourced CIO (OCIO), not a traditional family office. It manages capital for endowments, foundations, pension funds, and select high-net-worth families using a pooled investment vehicle. The firm does not serve a single family's wealth.

Partners Capital uses a proprietary manager research team that conducts on-site diligence and continuous monitoring of underlying fund managers. The firm's scale — $220B in assets — gives it access to managers that may be capacity-constrained or closed to smaller investors. Co-investment opportunities occasionally arise through its relationships with underlying GPs.

The firm primarily makes fund commitments to external managers across private equity, venture capital, and hedge funds. It also completes occasional direct co-investments alongside those managers, typically in larger deals where the firm's capital provides meaningful leverage. The co-investment program is not separately disclosed publicly.

Partners Capital allocates across the full venture-to-buyout spectrum, but has a preference for established-growth and buyout-stage private equity. Within venture capital, it seeks late-stage and growth-stage funds rather than early seed-stage vehicles. The real assets sleeve targets core-plus infrastructure and real estate funds.

The firm does not publicly maintain a formal exclusion list, but its portfolio historically avoids crypto-native venture funds, early-seed deployments, and public-market-only long-only strategies. Sector allocation follows the investment committee's macro assessment rather than a static preclusion.

Partners Capital serves a variety of institutional clients, including university endowments, charitable foundations, pension funds, and family offices. The firm does not disclose individual client names or their wealth sources. Its public reporting focuses on aggregate asset allocation and fund structure.
