Greycourt & Co.
Gregory D. Curtis established Greycourt in 1988, anchoring the firm's identity in the complex wealth-management needs of a Mellon family branch. As chairman and the principal owner of over 25% of the firm, Curtis shaped it into an independent advisory that serves ultra-high-net-worth families and select institutions from its Pittsburgh headquarters. The firm maintains deep ties to the original wealth-creation story while operating as a fiduciary that does not manufacture its own investment products. Greycourt constructs globally diversified, multi-asset portfolios across private equity, venture capital, private credit, hedge funds, real estate, infrastructure, and natural resources. The firm's open-architecture model means it allocates capital externally — through fund commitments, fund-of-funds structures, and direct co-investments — rather than deploying in-house strategies. Confirmed positions include client capital placed with SAC Capital (now Point72) and allocations to the Greycourt Partners Fund, a Pittsburgh-based pooled vehicle. The firm also invests in secondaries. Its geographic focus spans North America. Greycourt maintains an institutional-grade network for sourcing and diligence. The firm is a member of the Family Office Exchange independent advisor network and the Institute for Private Investors. Colony Family Offices engages Greycourt for research, manager due diligence, and asset allocation, illustrating its role as an outsourced investment office to other advisory firms. The firm also operates a real assets arm linked to the mixed-use property Adaptive Commons. Greycourt does not publicly disclose its total headcount or its precise AUM figure. Greycourt's structural distinction is its pure advisory posture: it acts as a fiduciary gatekeeper, not a principal investor. The firm's power comes from its independence from any single asset manager and its multi-decade embeddedness within the Mellon family ecosystem. That governance model — a founder-led shop with a concentrated ownership stake, advising multiple families through a single open-architecture platform — creates a sourcing and due-diligence advantage that balance-sheet investors cannot easily replicate.

Frequently asked questions
Who runs investment decisions at Greycourt?
Founder and Chairman Gregory D. Curtis retains principal ownership of more than 25% of the firm and sets the strategic direction. Greycourt operates an open-architecture model, meaning the investment committee and research team select and monitor external managers across public and private markets rather than making direct stock-picking or deal-underwriting decisions internally.
How does Greycourt source its manager opportunities?
Greycourt leverages its position as a founding member of the Family Office Exchange advisory network and its membership in the Institute for Private Investors. It also acts as an outsourced research and due-diligence provider for other advisory firms including Colony Family Offices. This reciprocal intelligence network provides early visibility into manager capacity and fundraises.
Is Greycourt structured as a single family office or a multi-family office?
Greycourt is a multi-family office. It traces its roots to advising a branch of the Mellon family's banking and industrial fortune but has expanded its client base to include other ultra-high-net-worth families and select institutions. The founder remains the majority owner of the advisory business.
Does Greycourt participate in fund commitments or only direct deals?
Greycourt uses both. The firm allocates to external private equity, venture capital, and hedge funds and also operates the Greycourt Partners Fund, a Pittsburgh-based pooled vehicle. Its investment types explicitly include Fund of Funds and direct co-investments, confirming it accesses opportunities through multiple structural paths.
Does Greycourt maintain philanthropic structures, and how are they separated?
Founder Gregory Curtis was instrumental in organizing the Family Foundations Section at the Council on Foundations, and Greycourt advises clients on governance and strategic planning that includes philanthropic capital. The firm itself does not operate a separate private foundation, though the principals have ties to the Laurel Foundation and the Pittsburgh Foundation.
What asset classes does Greycourt explicitly invest in?
Greycourt constructs multi-asset portfolios covering private equity, venture capital, private credit, hedge funds, real estate, infrastructure, and natural resources. The firm also participates in secondaries. It focuses on North American opportunities and does not claim direct public-equity stock-picking; public-market exposure is generally obtained through external managers.
Does Greycourt accept outside institutional capital?
Yes. While ultra-high-net-worth families form the core client base, the firm serves select institutions. Its structure is that of an independent registered investment adviser, not a private trust company, which permits it to manage assets for non-family clients including foundations and endowments.
