Firm profile
FINTRXOverview
Third Harbor is organized as a limited partnership and is registered with the SEC in 2026 as an institutional registered investment adviser. The firm’s owner type is listed as an individual and it identifies as a newly formed adviser. Its advisory activity is focused on portfolio management for pooled investment vehicles, and its stated fee arrangements include both a percentage-of-AUM component and performance-based fees. Third Harbor is not designated as a capital allocator and does not report active ESG investing activity. The firm is registered to operate within a single state rather than as a multi-state adviser. That profile and the pooled-vehicle focus suggest a fund-like operating model rather than a traditional multi-client RIA serving retail households.
