INDEPENDENT ASSESSMENT
Mare Liberum Critical Technologies Fund I, LP is a verifiable 2025 Delaware pooled investment fund whose new September 15, 2026 SEC Form D reports $25,805,500 sold to 17 investors following a first sale on August 31, 2026. The fund uses Rule 506(c), relies on Section 3(c)(1), offers pooled investment fund interests, has an indefinite offering amount, reports a technical $0 minimum investment and shows $0 estimated sales commissions and finder's fees in Item 15. Mare Liberum Critical Technologies Fund I GP, LLC is the General Partner, Mare Liberum Capital Partners, LLC is the management company, and Erik Bethel, Marc Baliotti, Vrushank Vora and retired Rear Admiral Lorin Selby appear in the related-person chain. The filing also states that the management company will receive management fees based on the amount of securities sold. The distinctive story is much larger than the $25.8 million SEC number: Mare Liberum announced earlier in 2026 that a critical-technologies fund had received a green-light letter from the U.S. Small Business Administration and the Pentagon's Office of Strategic Capital under the SBIC Critical Technologies program, creating a path to as much as $150 million of low-cost government-guaranteed leverage if the fund completes the required licensing and program steps.
That government-capital pathway materially changes how the vehicle should be understood. The Form D itself records private securities sales, not federal leverage, and the $25.8055 million sold should not be combined with the potential $150 million SBICCT leverage and presented as current fund size or NAV. Mare Liberum's March announcement described the vehicle as its second fund and said it was raising equity commitments from institutional investors after receiving preliminary program approval; the announcement did not state that the full $150 million had already been drawn. The distinction is critical: an SBA/OSC green-light letter can support a future leveraged capital structure, but investors still need to verify final SBIC licensing, the amount and timing of any leverage actually available, matching private-capital requirements, borrowing terms and restrictions on eligible investments. The new September Fund I LP filing appears inside the same Mare Liberum critical-technologies ecosystem, but public evidence does not fully reconcile every 2026 legal vehicle, including the separately filed Mare Liberum Critical Technologies Fund LLC and Mare Liberum Advanced Manufacturing Fund LLC, so those entities should not be casually treated as one pool.
THE UNIQUE STORY: "MARITIME DOMINANCE" IS THE PORTFOLIO FILTER, NOT JUST A DEFENSE LABEL
Mare Liberum's official site gives this fund a sharply differentiated thesis. The manager says it invests at the intersection of critical technologies and the maritime domain and frames oceans as strategic infrastructure supporting global trade, energy, communications and national security. Its three stated themes are emerging ocean platforms, national-security modernization and global-trade realignment. The public portfolio currently highlights Epirus for directed-energy and high-power microwave electronic-warfare systems, Windward for maritime-domain awareness using AI and multi-source vessel data, and a stealth AI-data-center initiative aimed at sovereign national-security infrastructure. This is not simply a broad defense-tech portfolio: the strategy is organized around technologies that can reshape maritime power, logistics, undersea awareness, autonomous systems and the resilience of supply chains and communications. The manager's March 2026 announcement further said the SBICCT strategy is expected to support AI, robotics, advanced manufacturing and autonomous systems, which creates a coherent bridge between the official portfolio and the government critical-technologies mandate.
The management team is also unusually aligned with that thesis. Erik Bethel previously served in senior U.S. government and international-finance roles; Marc Baliotti is a General Partner focused on the maritime investment thesis; Vrushank Vora is a General Partner; and retired Rear Admiral Lorin Selby, a former senior U.S. Navy officer, gives the platform direct operational naval experience. The advisory board includes former Navy Secretary Kenneth Braithwaite, former State Department official Paula Dobriansky, former NOAA leader and Navy oceanographer Timothy Gallaudet, gCaptain founder John Konrad, former Deputy National Security Advisor Matthew Pottinger and former Federal Maritime Commission chairman Louis Sola. That roster is not proof of investment performance and should not be used as a substitute for portfolio diligence, but it is directly relevant to a strategy whose competitive advantage depends on understanding naval procurement, maritime operations, critical infrastructure and national-security adoption pathways. The Department of Defense's own 2025 directory of defense-oriented investors also listed Mare Liberum Capital Partners among venture firms active in the sector, independently confirming the platform's defense-tech positioning.
FINAL ASSESSMENT
Mare Liberum Critical Technologies Fund I has a strong legal and thematic verification profile and one of the more unusual capital structures in this recent Form D set. The September 2026 filing confirms $25.8055 million sold to 17 investors under Rule 506(c) and Section 3(c)(1), while the manager's official materials independently document a maritime-focused critical-technologies strategy and a preliminary SBICCT pathway that could provide up to $150 million of government-guaranteed leverage. The central diligence issue is therefore not whether the sponsor exists, but how private LP capital, potential federal leverage and multiple related Mare Liberum legal vehicles fit together. Investors should verify final SBICCT licensing status, actual leverage available or drawn, the relationship among Fund I LP, Critical Technologies Fund LLC and Advanced Manufacturing Fund LLC, management and carried-interest terms, eligible-investment restrictions, current portfolio attribution and the extent to which defense or government customers influence revenue timing and exit outcomes. Form D verifies the exempt offering; a government program green light does not constitute SEC, SBA or Pentagon approval of investment performance.
SEC SNAPSHOT
SEC CLASSIFICATION: Pooled Investment Fund / Other Investment Fund | SECURITY: Pooled Investment Fund Interests | EXEMPTION: Rule 506(c) | ICA EXCLUSION: Section 3(c)(1) | FIRST SALE: August 31, 2026 | OFFERING: Indefinite | DURATION: More than one year.
SALES-COMPENSATION RECIPIENT: BHA Select Network, LLC | CRD 168883 | solicitation disclosed in Florida, Massachusetts and New York | Item 15 estimated commissions: $0.
ITEM 16: $0 estimated related-person use of proceeds, with clarification that the management company will receive management fees based on securities sold.
IMPORTANT CAPITAL DISTINCTION: $25.8055M is cumulative Form D securities sold. The announced potential $150M SBICCT leverage is a separate government-backed financing pathway and should not be added to Form D sales as current NAV or AUM unless actually licensed, drawn and documented.
WEBSITE / ENTITY PENETRATION

CORE INVESTOR QUESTIONS
Has Mare Liberum completed final SBICCT licensing after the green-light letter | How much of the potential $150M leverage is currently available or drawn | What private-capital matching requirements apply | Is the government leverage senior to LP equity and on what repayment terms | How are Fund I LP, Critical Technologies Fund LLC and Advanced Manufacturing Fund LLC related | Are they parallel, feeder, co-investment or separate strategy vehicles | Which current portfolio companies belong specifically to Fund I LP | What percentage of assets can be invested in one company | What management fee and carried interest apply | Does the fund charge fees on committed equity, invested equity or government leverage | What restrictions accompany SBICCT capital | How much portfolio revenue depends on U.S. government contracts | How are export controls, classified programs and foreign ownership restrictions handled | What follow-on reserve is maintained for capital-intensive defense and advanced-manufacturing companies
CORE RISKS
Government-program execution risk | final SBIC licensing risk | leverage risk | defense-procurement timing | customer concentration in government agencies | export-control risk | classified-program opacity | maritime-sector concentration | advanced-hardware manufacturing risk | robotics and autonomy execution risk | long procurement cycles | follow-on financing needs | valuation risk | cross-vehicle allocation complexity | multiple Mare Liberum legal issuers may create confusion | potential $150M leverage should not be mistaken for current fund assets | Form D sales do not equal NAV.
INDEPENDENT CONCLUSION
Mare Liberum Critical Technologies Fund I stands out because the fund combines private Regulation D capital with a potential government-backed leverage channel designed specifically for critical technologies. The SEC filing confirms $25.8055 million sold to 17 investors under Rule 506(c), while the manager's public materials show a focused maritime-defense thesis and a government program pathway that could materially expand deployable capital if final SBICCT requirements are met.
The most important diligence work is structural. Investors need to map Fund I LP against Mare Liberum's other 2026 critical-technologies and advanced-manufacturing issuers, determine which entity is the SBICCT applicant or licensee, verify the amount of leverage actually available, and identify which portfolio companies sit in each legal vehicle. The maritime-security thesis is clear; the remaining question is how the capital stack and legal architecture implement it.
