The Tides Group

The Tides Group is a San Francisco multi-family office, chaired by Eric Brown, with estimated $10B–$20B assets under advisement.

The Tides Group

The Tides Group opened in San Francisco in 1986, founded by Eric Brown alongside a small circle of West Coast families (public record). The firm has never disclosed a single client base or wealth origin, consistent with its deliberately opaque posture. It now operates as a multi-family office for a network of high-net-worth families, with a team of roughly 25 professionals. The firm structures capital across direct real estate and infrastructure deals, alongside a technology venture portfolio that includes early-stage bets in infrastructure software and healthcare delivery. Known co-investment partners include institutional funds and other family offices (per public record). Geographically, it focuses on North America, with occasional allocations to Europe and Asia. The Tides Group does not operate a traditional fund vehicle; all commitments are made through SPVs or direct co-investments tailored to client mandates. With an estimated $10B–$20B in collective assets under advisement (Altss estimate), the firm maintains a single San Francisco office. Its philanthropic arm, the Tides Foundation, operates as a donor-advised fund intermediary, legally separate but mentioned in connection with the same group of families. Recent activity was not available from public sources. The Tides Group's structural differentiator is its hybrid identity: it functions both as a multi-family office and as a direct investment firm, with no fund vehicles or commingled structures. This allows it to preserve client anonymity while aggregating capital for large, illiquid deals — an approach that limits benchmarking but affords flexibility.
