## About

Harbourton Enterprises traces to 1990 when Jay Regan established the office following his tenure at Princeton Newport Partners, the quantitative hedge fund he co-founded with Edward Thorp. The firm oversees Regan family capital that originated in statistical arbitrage and later expanded into distressed opportunities. Deployment spans public securities, direct co-investments, private equity, private credit, hedge funds, real estate, infrastructure, natural resources, and digital assets. Confirmed investment stages include early and late stage. Geographic reach covers North America and Europe. The office has recorded exposure to Alameda Research and FTX. The team includes David W. Mills as Managing General Partner alongside family members Amy Regan, Jason Regan, and James S. Regan III. Additional offices operate in New York and Santa Cruz. The Harbourton Foundation serves as the primary philanthropic vehicle, with David Mills holding board roles at the NAACP Legal Defense Fund and QuestBridge. The structure separates investment management at Harbourton Enterprises from grantmaking at the Harbourton Foundation, with the latter maintaining a grantee-centric process focused on food equity and land access.
