Spinnaker Capital

Spinnaker Capital, based in Boston with offices in Cambridge, New York, and West Palm Beach, appears to operate as a multi-family office serving a select group of wealthy families. The firm was established prior to 2015, based on public record filings, though its founding year and principals remain undisclosed. The firm's strategy spans private equity, real estate, and venture capital, with a focus on direct investments alongside external fund commitments. Known positions include co-investments in middle-market companies and real estate assets across the U.S. Northeast and Southeast, according to public filings. The geographic footprint covers North America, with emphasis on metropolitan areas. Team size and total assets under management are not publicly disclosed. The firm maintains a low profile, with no named investment professionals or affiliated vehicles appearing in public registries. Recent activity includes a 2023 filing for a real estate joint venture in Florida (per public record, 2023). Spinnaker Capital's key structural differentiator is its multi-family office model combined with a direct investment focus — a hybrid structure rare among East Coast family offices. The firm likely relies on a lean team and co-investment partnerships to access deals without building a large internal staff.
