## About

The Jarosz Family Fund is a single-family office based in San Francisco, with additional offices in Miami, Los Angeles, and Seattle. The firm was established by the Jarosz family to manage its private wealth, though the specific founding date and identity of the family patriarch or matriarch have not been publicly confirmed. The wealth origin—whether from technology, real estate, finance, or another sector—remains undisclosed. The family office pursues a diversified investment strategy, with public record indications of allocations to private equity, real estate, venture capital, and direct investments. The firm has been linked to deals in technology and infrastructure sectors, though specific portfolio companies or co-investors have not been named in public filings. Its geographic footprint covers at least four U.S. No team size or principal names have been reported, nor has the firm disclosed AUM or annual deployment figures. The multi-city presence may indicate a dispersed team or multiple related entities, but details are sparse. There is no record of adjacent philanthropic foundations or operating companies publicly tied to the fund as of 2026. The firm's structural differentiator lies in its opacity: it has avoided any public profile, media coverage, or regulatory filings that would reveal its leadership, size, or investment approach. This seclusion makes it an outlier among single-family offices, which increasingly use branding and communication to attract co-investment partners or talent.
