Phi Square Holdings SA

Phi Square Holdings SA

Phi Square Holdings SA was established as a family office based in Herzliya, Israel, with a structure that remains largely opaque to public records. The firm maintains satellite offices in Burlingame, California, and New York City, suggesting a focus on North American and Middle Eastern markets. Its founding wealth origin and principals have not been publicly disclosed. The firm's investment strategy spans private equity, venture capital, and real estate, with a likely emphasis on technology and innovation-driven sectors given its Tel Aviv-area base and Silicon Valley presence. The office appears to operate through direct investments and co-investment vehicles, though specific portfolio companies or deal sizes remain unconfirmed. Geographic footprint includes Israel, the United States, and potentially broader global markets. No team size or deployment figures have been disclosed. The office's three-location structure — Herzliya, Burlingame, New York — implies a lean, operationally flexible team capable of sourcing deals across time zones. No philanthropic or adjacent vehicles have been publicly identified. The firm's structural differentiator lies in its deliberate opacity and tri-continental office network, which allows for direct deal sourcing in both Israeli tech and US markets. This low-profile model, combined with a diversified asset allocation, suggests a preference for control and discretion over external visibility.
