Gray Lake Advisors

Matthew Pritzker is the managing principal and makes investment decisions. He is a direct descendant of the Pritzker family, whose fortune was built on the Marmon Group industrial holdings and Hyatt Hotels. Gray Lake serves as his personal family office and does not operate with an external investment committee.

Gray Lake manages Matthew Pritzker's personal allocation separately from Pritzker Group, the multi-branch family office that oversees a larger pool of Pritzker family capital. The Pritzker fortune was divided among heirs during a restructuring in the early 2000s, leading several family members to form independent offices. Gray Lake's investment decisions are made independently of Pritzker Group's private capital, venture, and asset management arms.

No. Gray Lake is structured as a single-family office exclusively for Matthew Pritzker. It does not raise capital from external limited partners and does not market funds. All capital deployed is Pritzker-family equity, which gives the office flexibility to hold assets indefinitely without fund-life constraints.

Gray Lake targets direct private credit opportunities — including real estate bridge loans and structured preferred equity — and control buyouts of profitable lower-middle-market companies. The office does not participate in seed-stage venture or early-growth minority deals. Its real estate strategy focuses on income-producing multifamily and industrial assets rather than ground-up development.

The wealth traces to the Pritzker family's acquisition and growth of the Marmon Group, a diversified industrial manufacturer, and the construction of the global Hyatt Hotels chain. The family sold a controlling stake in Marmon to Berkshire Hathaway beginning in 2007. Matthew Pritzker's share of the distributed family fortune was seeded during the early-2000s restructuring of the dynasty's holdings.

Matthew Pritzker participates in the family's broader civic and philanthropic efforts in Chicago, but Gray Lake Advisors is an investment office, not a philanthropic entity. The Pritzker Foundation and the Pritzker Traubert Foundation operate as separate organizations with their own governance. Gray Lake's investment decisions are not directed by philanthropic objectives.

Gray Lake will co-invest selectively with other family offices and institutional credit funds on real estate debt and private credit transactions. The office does not operate a formal co-investor club, and its participation is typically sourced through long-standing banking relationships in the Midwest. Co-investments tend to be structured as pari-passu direct positions rather than fund-of-fund commitments.
