Maxcess International

The capital originates from Cameron Iron Works, a Houston-based manufacturer of oilfield pressure-control equipment and blowout preventers. The Forbes family controlled the company through much of the 20th century. In 1989, Cameron Iron Works merged with Cooper Industries, generating liquidity that seeded the family's investment office.

William Cameron Forbes is the named principal tied to the office. The Forbes family manages investment decisions through a private governance structure that has not historically employed outside chief investment officers or external management firms. Operational details remain tightly held, consistent with a single-family office that does not market to outside investors.

Maxcess International is structured strictly as a single-family office serving the Forbes family. There is no public record of the firm converting to a multi-family office, accepting external limited partners, or offering investment services to other families. It operates outside the registered investment-adviser framework that would accompany third-party capital.

The firm deploys capital across real estate, private equity, and industrial technologies. Real estate investments concentrate on commercial and mixed-use properties in Texas, Oklahoma, and surrounding Sun Belt markets. The private equity book favors hard-tech, energy services, and advanced manufacturing — sectors that align with the family's industrial operating history.

The office is historically connected but operationally independent. Cameron Iron Works merged with Cooper Industries in 1989, and the Cameron brand later moved through Cooper Cameron Corporation and eventual acquisition by Schlumberger in 2016. Maxcess International manages the Forbes family's capital separately from those corporate entities and has no current operational linkage to Schlumberger or Cameron.

The Forbes family maintains philanthropic grantmaking through separate foundation structures. These are legally distinct from the investment office. Grants have historically supported education, medical research, and civic institutions in Texas and Oklahoma, but the foundation entities do not comingle assets with the investment portfolio.

The office is stage-agnostic, writing checks across early-stage ventures, growth-equity rounds, and direct real estate acquisitions. The absence of outside LP capital allows Maxcess to hold positions through full asset lifecycles — including commodity downturns — without the pressure of fund-duration limits or quarterly redemption gates.
