Schooner Capital

Schooner Capital

Schooner Capital was established in 1971 by Vin Ryan. Ryan built Iron Mountain into a $30 billion records-management enterprise and later created the firm to manage the resulting private capital. The office remains anchored in Boston and continues to operate from a permanent capital base. The firm invests in private companies and public securities across technology, healthcare, and services. It participates in buyouts, growth equity, venture capital, and seed rounds through direct co-investments and SPVs. Portfolio holdings include companies developing AI-driven industrial optimization, mRNA cell therapies, commercial fusion energy, and vendor risk management software. Positions span North America, Europe, and Oceania. Public equity holdings are global and concentrated in companies with strong returns on invested capital. The team includes multiple managing partners who maintain active involvement with portfolio companies. Schooner lists no additional offices. Profits support The Schooner Foundation, which focuses on human rights causes. Vin Ryan serves on boards including the Carr Center at Harvard Kennedy School and The Nature Conservancy. No operational events from the last 24 months appear in public records. The office maintains an evergreen structure that removes fundraising timelines and allows repeated investment in the same holdings. This architecture stems directly from Ryan's experience building and holding Iron Mountain over decades rather than from a typical limited-partnership cycle.
