Frequently asked questions
Who runs investment decisions at Seabridge?
Margaret McGrath, the founder and managing partner, leads investment decisions. She built the firm in 1999 after prior institutional portfolio management experience and is directly involved in manager selection and portfolio construction.
How does Seabridge source its hedge fund managers?
Seabridge emphasizes relationship-driven origination and often invests with emerging or capacity-constrained managers before they become widely known. The firm's concentrated portfolio approach — backing a small number of funds rather than a broad index — requires them to find managers with genuine structural edges that may be closed to the broader allocator community.
Does Seabridge invest only in hedge funds, or does it also commit to private equity and venture?
Seabridge's core strategy runs through hedge fund managers spanning long/short equity, distressed credit, event-driven, global macro, and relative value. The firm may facilitate secondary-market transactions and special-situation opportunities for clients, but its primary mandate is not direct private equity or venture capital.
Is Seabridge a single-family office or a multi-family office?
Seabridge operates as an independent advisory firm serving multiple families, foundations, and institutional clients rather than managing the capital of a single wealthy family. Its concentrated portfolio construction model, however, mirrors how an internal CIO would oversee a single-family office's hedge fund book.
What investment stages or strategies does Seabridge explicitly avoid?
As a concentrated hedge fund allocator, Seabridge generally avoids broad retail-oriented long-only equity and fixed-income products that can be accessed passively. The firm does not position itself as a venture capital allocator and has not publicly signaled involvement in direct early-stage technology investing.
Where does the underlying client wealth come from?
Specific wealth origins of Seabridge's client base are not publicly disclosed. The firm serves multiple families and foundations rather than being the dedicated investment office for a single named fortune.
Does Seabridge maintain any philanthropic structures or adjacent vehicles?
There is no public record of Seabridge operating a separate philanthropic foundation or launching pooled investment vehicles under its own brand. The firm's model focuses on custom advisory portfolios for each client rather than commingled proprietary funds.
