INDEPENDENT VERDICT
Double River US Feeder Funds LP - Double River Emerging Markets has one of the most concentrated capital profiles in this group. Its original August 13, 2025 Form D reported $0 sold and no first sale; the September 10, 2026 amendment now reports $44,101,500 sold to only two investors after a December 1, 2025 first sale. The Delaware partnership is classified as a hedge fund, relies on Rule 506(b) and Section 3(c)(7), and identifies Double River Management Limited as General Partner, with Stuart Orgill and Otso Fristrom serving as directors of that GP. A simple average would put the two subscriptions at roughly $22 million each if evenly sized, although the actual investor allocations are not public. The filing therefore looks far more institutional or concentrated than a broadly distributed private fund, but the SEC record does not identify the two investors or establish whether either is itself a feeder, institution, family office or affiliated entity.
THE REAL STORY IS A MULTI-JURISDICTION FUND ARCHITECTURE, NOT ONE "DOUBLE RIVER FUND"
Double River has built at least two strategy families through parallel U.S. and Cayman access vehicles. The Emerging Markets side includes the Delaware Double River US Feeder Funds LP - Double River Emerging Markets and Cayman-based Double River Feeder Funds SPC - Emerging Markets SP. The Absolute strategy similarly uses Double River US Feeder Funds LP - Double River Absolute alongside Double River Feeder Funds SPC - Absolute Feeder SP. All of these entities use 505 Montgomery Street, 11th Floor in San Francisco, the same 424-327-4837 telephone number and the same Double River Management Limited / Stuart Orgill / Otso Fristrom management chain. The Cayman Absolute vehicle's filing explicitly identifies Double River Management Limited as investment manager, while the U.S. Emerging Markets vehicle identifies it as General Partner. This pattern strongly supports one operating platform using different legal wrappers for strategy and investor type, but the reviewed Form Ds do not identify the ultimate master funds or quantify cross-vehicle ownership. Their Form D amounts therefore should not be blindly added into one Double River AUM number.
THE SEPTEMBER 2026 AMENDMENTS SHOW CAPITAL FORMATION IN THE FEEDERS WHILE A NEW "DEEP VALUE" VEHICLE WAS STILL AT $0
Double River's structure became even more interesting in 2026. On May 4, Double River Emerging Markets Deep Value filed a new Form D from the same San Francisco address with the same Double River Management Limited, Stuart Orgill and Otso Fristrom control group. That vehicle was classified as a hedge fund, relied on Rule 506(b) and Section 3(c)(7), offered participating shares indefinitely and reported $0 sold with no first sale yet. LEI records separately identify an active Cayman vehicle named DOUBLE RIVER FUNDS SPC - EMERGING MARKETS DEEP VALUE SP whose headquarters are care of Double River Management Limited at the same Montgomery Street office. This creates a second layer inside the emerging-markets franchise: a broad Emerging Markets feeder complex that had already accumulated $44.10 million in its U.S. sleeve, alongside a newer Deep Value sub-strategy whose public offering was still pre-first-sale in May. The relationship between the broad Emerging Markets strategy and Deep Value should not be inferred without the offering memoranda.
THE MANAGER'S PUBLIC FOOTPRINT IS THINNER THAN ITS SEC FUND FOOTPRINT
FilingDossier did not independently confirm a dedicated Double River investment-management website with strategy, portfolio, audited performance or team biographies matching the SEC legal entities. The clearest non-SEC branding evidence is a U.S. trademark application for DOUBLE RIVER filed in February 2025 by Stuart Orgill for "funds investment," with the trademark record claiming first use dating to 2016. Orgill also has a public history connected to Double River Investment and later founded circular-chemicals business Encina One, but those outside business activities should not be attributed to the current Double River hedge funds without direct fund documentation. The absence of a developed public website is notable because the regulatory entity network is already substantial: multiple feeder funds, two strategy families and more than $44 million reported in just one U.S. feeder. For investors, the missing evidence is therefore portfolio-level rather than entity-level — current holdings, country exposures, liquidity, prime brokerage, administrator, auditor and valuation procedures are not visible from the Form Ds.
FINAL ASSESSMENT
Double River Emerging Markets is defined by at least five facts that make it highly specific: its U.S. feeder went from $0 to $44.1015 million in reported sales; only two investors account for that amount; a Cayman Emerging Markets feeder exists alongside it; a separate U.S./Cayman Absolute pair uses the same manager and infrastructure; and a newer Emerging Markets Deep Value vehicle appeared in 2026 with the same Orgill/Fristrom management chain but initially $0 sold. The central diligence issue is therefore architecture. Investors need to know which master portfolio receives each feeder's capital, whether U.S. and Cayman investors participate pari passu, whether Deep Value is a separate portfolio or sleeve within Emerging Markets, and how management and performance fees are layered. The September amendment confirms that Double River has attracted meaningful concentrated capital, but it does not by itself reveal the ultimate portfolio or consolidated platform size.

IMPORTANT FORM D NOTICE
The $44,101,500 reported in the September 2026 amendment belongs specifically to Double River US Feeder Funds LP - Double River Emerging Markets. It should not be interpreted as consolidated Double River AUM or automatically added to capital reported through the Cayman Emerging Markets, Absolute or Deep Value structures.

Likewise, the existence of a Form D, CIK, LEI or trademark does not constitute SEC approval, adviser registration, endorsement or verification of investment performance.
