Account Management

The firm does not publicly disclose its investment committee or officers. John B. Hess, Leon Hess's son, is the public steward of the family's operating and investment interests through his role as long-time CEO of Hess Corporation, but the investment office operates with a separate management structure that has remained unlisted in any public record or news report. This deliberate opacity is central to its operating model.

Two major liquidity events have shaped the family's investable asset base. In 2014, Marathon Petroleum acquired the Hess retail network for $5.3 billion, converting the downstream operating business into investment capital. In October 2024, Chevron completed its $53 billion acquisition of Hess Corporation, delivering Chevron stock worth approximately $5 billion to the Hess family trust, which is managed alongside existing assets (per Chevron public filings, October 2024).

Based on public fund-tracking records and transaction reports, the firm allocates across long-only public equities, hedge funds, private equity fund commitments, and private credit. It tends to favor manager selection over direct investing, with the notable exception of real estate assets tied to the family's legacy energy footprint in the Bakken shale region and Gulf Coast logistics corridors.

No. The firm is structured exclusively for the Hess family and its trusts. It does not solicit or accept external capital. However, it does participate in co-investment vehicles alongside a small circle of peer family offices, typically through fund-of-one structures where the investor base remains private.

The Hess family channels charitable giving primarily through the Leon Hess Foundation and the Hess Philanthropic Fund, which have deployed hundreds of millions of dollars in grants to healthcare institutions, educational programs, and Jewish community organizations. These foundations are governed separately from the investment office, with independent boards and no commingled staff, walling off grantmaking from portfolio management.
