Independent research on semi-liquid alternatives.
AltHarbor publishes structured editorial coverage of non-traded BDCs, interval funds, perpetual PE and infrastructure vehicles, tender offer funds, and non-traded REITs — built for advisors, allocators, and researchers who need answers the sponsor websites won't give them.
Our Mission
To make the semi-liquid alternatives market legible. Fund data traces to primary filings and official source documents; editorial may cite public market and media sources when the context is clearly labeled. No ratings. No sponsor relationships. No paywall.
Our Values
Primary-source discipline
Fund data starts with SEC filings, official fund documents, and labeled source dates before it becomes a product view.
Source trail
The useful number is never enough by itself; AltHarbor keeps the filing trail and context close to the figure.
Explain the mechanics
Fees, gates, tender windows, share classes, and marks should read like operating mechanics, not sponsor copy.
No sponsor economics
Coverage is not sold to managers, distributors, or platforms. The product is the research surface itself.
How AltHarbor is built
AltHarbor is an independent editorial project, currently operated by a single editor. There is no sales team, no sponsor desk, and no advisory arm. Coverage decisions are made on the basis of what semi-liquid alternative products exist in the market, not on who pays.
Every numerical claim on a fund page is extracted from public SEC filings — 10-Ks, 10-Qs, N-CSRs, and 424B3 prospectuses. Fee decomposition, portfolio concentration, Level III exposure, capital flows, and liquidity mechanics are parsed directly from primary documents and structured into a consistent schema. AltHarbor does not republish content; it cites and links to the underlying source for every figure.
The site is in active development. Coverage currently spans 36 funds across private equity, private credit, private real estate, and private infrastructure. The Funds command board and Compare tool connect source trails, pressure signals, and fund-level context as coverage expands.
