Gillson Capital
Gillson Capital is a multi-family office based in San Francisco, founded in 2005 by Glenn Gillson.
Gillson Capital
Glenn Gillson founded the firm in 2005, naming it after himself and his family. The firm describes itself as a private investment office, though it structures some co-investment vehicles for a limited number of families and institutions. The underlying wealth origins of the Gillson family are not publicly documented. Gillson Capital's strategy spans real estate, private credit, and venture capital. The firm targets direct investments rather than fund-of-funds positions. In real estate, Gillson Capital has been associated with both debt and equity transactions in the US West Coast market. In private credit, it structures senior and mezzanine debt deals. Venture investments appear concentrated in early-stage technology companies, though specific portfolio names are not widely reported. Geographic focus is primarily the United States, with some exposure to Western Europe. The firm operates from a single San Francisco office. Team size is not publicly disclosed, but public filings suggest a small group of investment professionals. No separate philanthropic entity or adjacent operating company has been identified in public records. Gillson Capital's structural differentiator is its lean, direct-deployment model. Unlike many multi-family offices that allocate capital primarily through external funds, Gillson Capital leads or co-leads direct transactions, maintaining control over deal structures. The firm has not disclosed any succession plan, which — given the founder's length of tenure — may become a governance question for co-investors.
