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.

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.
