ONE MIND
ONE MIND was established by William B. Stevenson III, whose wealth originated from the technology industry. The family office structures its investment program around direct equity positions and co-investments with external general partners, focusing on healthcare and technology sectors. The firm targets early-stage venture through growth-stage private equity, deploying capital into companies such as those in healthcare services and software. ONE MIND participates in syndicated rounds alongside other family offices and institutional investors. Its geographic footprint centers on the United States, with a concentration on technology hubs. ONE MIND operates with a lean team and does not disclose total assets or professional count. The firm has no publicly listed additional offices beyond its US base. There is no recent publicly verifiable activity within the last 24 months to report; the firm maintains a low public profile and does not regularly issue press releases or announce deals. A structural differentiator of ONE MIND is its low-profile, direct-investment approach — the firm does not manage third-party capital and relies solely on Stevenson's personal wealth. This structure allows for long-duration investment horizons without the liquidity or reporting constraints of a commingled fund.
