INDEPENDENT VERDICT
Okeanos Venture Partners is one of the clearest examples in this research batch of a private-investment platform that should not be analyzed as one conventional venture fund. SEC records show Okeanos Venture Partners I, LLC alongside a very large number of separately numbered Series, followed by Okeanos Venture Partners II, LLC with the sequence continuing beyond Series 180. The latest reviewed vehicle, Okeanos Venture Partners II LLC-Series 181, filed on August 4, 2026 and reported a fully sold $323,684 offering to eight investors only days after its July 28 first sale. Another recent vehicle, Series 174, had reached $609,500 sold to 33 investors by July 31. Those deal-sized offerings sit beside the original Okeanos Venture Partners I, LLC, which reported approximately $17.11 million in its 2023 Form D. The distinctive story is therefore scale by repetition rather than scale by one giant fund: Okeanos Venture Management LLC acts as manager across a broad series architecture, while Mark Dumas, Aaron Berkey, Jason Parikh and Shap Bashar recur throughout the filings.
THE "FUND" IS REALLY A FACTORY OF SEPARATE SERIES
The legal architecture is unusually explicit. Okeanos Venture Partners I, LLC was formed in Delaware in 2023, but the SEC filing package simultaneously identifies numerous separately numbered Series beneath that master structure—Series 3, 8, 10, 11, 19, 26, 27, 28, 38, 50, 59, 68, 71, 78, 88, 97 and others. The second-generation platform, Okeanos Venture Partners II, LLC, was organized in 2022 and continued the numbered sequence well past 100, including Series 114, 115, 136, 137, 147, 149, 166, 168, 169, 174, 180 and 181. Each Series has its own CIK and can file its own Form D, meaning each is a separate SEC issuer rather than simply a share class inside one pooled vehicle. The filings repeatedly identify Okeanos Venture Management LLC, or OVM, as manager of the issuer. This makes the correct investor question highly vehicle-specific: "Which Series am I actually buying, and what underlying asset does that Series own"
SERIES 181 AND 174 SHOW HOW SMALL, FAST AND FULLY SUBSCRIBED THESE VEHICLES CAN BE
Series 181 is a strong example of how the platform operates. The issuer was formed under the Okeanos Venture Partners II umbrella, filed on August 4, 2026, classified itself as a private equity fund, relied on Rule 506(b) and Section 3(c)(1), and reported a July 28 first sale. The total offering was exactly $323,684, the full $323,684 had already been sold, nothing remained, and eight investors had participated. Aaron Berkey signed the filing as manager of Okeanos Venture Management LLC, acting as manager of the issuer. Series 174 followed the same legal pattern but was larger: by July 31, 2026 it reported a $609,500 offering fully sold to 33 investors after a March 23 first sale. Neither filing reported sales commissions or finder fees. These numbers are far below the size of a traditional institutional venture fund and are much more consistent with transaction-specific SPVs or syndicated private-company opportunities.
THE ORIGINAL $17.1M VEHICLE IS A DIFFERENT LAYER FROM THE SERIES SPVS
The October 30, 2023 Form D for Okeanos Venture Partners I, LLC reported approximately $17,109,496 and identifies Okeanos Venture Management LLC as manager and promoter. The management roster includes Mark Dumas, Aaron Berkey, Jason Parikh and Shap Bashar. That larger master-level vehicle should not be treated as the sum of every later Series or as proof that each numbered Series is diversified. The legal pattern instead suggests a platform where a master or flagship entity can coexist with many deal-specific issuers. Some Series raise only a few thousand dollars, others hundreds of thousands or more than $1 million. For example, Series 71 was reported at only $7,998, while Series 166 initially raised about $1.636 million before a small 2026 amendment. The dispersion in offering size is a major clue that numbered Series are not simply identical annual fund vintages.
MANAGEMENT CONTINUITY IS STRONGER THAN PUBLIC WEBSITE TRANSPARENCY
The best identity evidence comes from the SEC management chain rather than from a heavily marketed public website. Across the recent Series filings, Okeanos Venture Management LLC is consistently identified as manager. Mark Dumas is described as a manager of OVM, Aaron Berkey as a manager of OVM, Jason Parikh as a manager of OVM and Shap Bashar as a manager of OVM. The telephone number 703-929-0784 persists from the earlier Great Falls, Virginia filings to the newer Norfolk, Virginia address at 440 Monticello Avenue, Suite 1802 PMB 98895. That continuity across people, manager entity and phone number is stronger evidence than a name match alone. FilingDossier did not find enough public website disclosure to independently map each numbered Series to an underlying portfolio company, so the website layer remains secondary to the SEC record for legal-entity verification.
THE MAIN RISK IS NOT WHETHER THE PLATFORM EXISTS — IT IS WHAT EACH SERIES ACTUALLY OWNS
A high-volume Series platform can be efficient for investors who want selective exposure to individual private-company opportunities, but it creates a different diligence burden from a blind-pool venture fund. Every Series can have a different underlying company, security type, valuation, ownership percentage, follow-on right and fee structure. Series 181's $323,684 and eight investors tell investors almost nothing about what asset was purchased. The same is true for Series 174's $609,500 and 33 investors. The SEC filings confirm that the Series exist and that OVM manages them, but they do not publicly identify the portfolio company or explain whether the vehicle buys common stock, preferred shares, SAFE notes, convertible securities or another interest. For Okeanos, document-level review of each Series is therefore more important than manager-level AUM.
FINAL ASSESSMENT
Okeanos Venture Partners has an unusually large and internally consistent Form D footprint, with a numbered-Series architecture extending beyond 180 separate issuers and a recurring management chain through Okeanos Venture Management LLC. The latest 2026 filings show active deal creation rather than a dormant platform: Series 174 and 181 were both fully sold, while other 2026 Series continue the same legal and management pattern. The original Okeanos Venture Partners I vehicle provides a larger $17.1 million platform-level anchor, but the hundreds of individual Series should not be merged into one headline fund size or treated as one diversified portfolio.
For investors, the key question is always the exact Series. Public SEC records can confirm the issuer, offering size, investor count, manager and exemption, but they often do not disclose the underlying asset. The most useful diligence therefore concerns the company being purchased, price paid, security class, markup or SPV fee, carry, governance rights and whether the Series has follow-on obligations. Okeanos's regulatory footprint verifies the platform architecture; it does not make each individual Series equivalent in quality, diversification or risk.

FIVE FACTS UNIQUE TO THIS CASE
- Okeanos has created separately numbered SEC issuers extending beyond Series 180 rather than relying on one conventional VC fund.
- Series 181 was fully sold at exactly $323,684 to eight investors only days after its July 28, 2026 first sale.
- Series 174 was fully sold at $609,500 to 33 investors, showing that similarly numbered vehicles can have very different sizes and investor bases.
- The original Okeanos Venture Partners I vehicle reported approximately $17.1 million in 2023 while many individual Series raise only thousands or hundreds of thousands of dollars.
- Okeanos Venture Management LLC, Mark Dumas, Aaron Berkey, Jason Parikh and Shap Bashar recur across the Series filings even as the platform address moved from Great Falls to Norfolk.
CORE INVESTOR QUESTIONS
- What underlying company does the specific Okeanos Series own
- What security type did the Series purchase
- At what company valuation did the investment occur
- Did Okeanos purchase securities directly from the company or from an existing shareholder
- What SPV administration fee applies
- What management fee applies
- What carried interest or performance allocation applies
- Does the Series charge a markup or sourcing fee above the underlying security purchase price
- Does each Series have follow-on investment rights
- Are investors obligated to fund later rounds
- Can Okeanos Venture Partners I invest alongside individual Series
- How are attractive deals allocated among the flagship vehicle and separate Series
- Are liabilities legally segregated between Series
- Who maintains custody or records ownership of the underlying private securities
- What happens to a Series after the underlying company exits or fails
ENTITY-SPECIFIC RISKS
Each Series may represent highly concentrated exposure to one private company. The Form D usually does not reveal the underlying portfolio company. Series numbers provide almost no economic information by themselves. A $0 Form D minimum does not establish the actual subscription minimum. Small SPVs can carry proportionally significant legal and administrative costs. Hundreds of separate issuers increase operational and recordkeeping complexity. Investors need to verify that liabilities are properly segregated among Series. Manager-level history does not establish the quality of a particular underlying deal. A fully sold Series says nothing about the current value of the private-company security. The original $17.1 million platform raise should not be treated as current AUM or combined mechanically with all Series offerings.
PRIMARY EVIDENCE REVIEWED
U.S. Securities and Exchange Commission Form D filed August 4, 2026 for Okeanos Venture Partners II LLC-Series 181. U.S. Securities and Exchange Commission Form D/A filed July 31, 2026 for Okeanos Venture Partners II LLC-Series 174. U.S. Securities and Exchange Commission Form D records for Okeanos Venture Partners I, LLC. SEC filing records for Okeanos Venture Partners I numbered Series. SEC filing records for Okeanos Venture Partners II Series 114, 115, 136, 137, 147, 149, 166, 168, 169 and other related issuers. Public Form D index records confirming recurring Okeanos Venture Management LLC and management personnel.
IMPORTANT FORM D NOTICE
Form D is a notice of an exempt securities offering and does not represent SEC approval, endorsement or verification of Okeanos Venture Partners, Okeanos Venture Management LLC or any underlying private company. In this case, each numbered Series is a separate issuer and may represent a different investment opportunity. FilingDossier therefore does not combine Series-level offerings into one fund-size figure or assume that one Series' economics, portfolio company or performance applies to another.
