INDEPENDENT ASSESSMENT
Mare Liberum Critical Technologies Fund I, LP is a verifiable 2025 Delaware pooled investment fund whose new Form D was filed on September 15, 2026 after a first sale on August 31. The filing reports an indefinite offering with $25,805,500 sold to 17 investors, Rule 506(c), Section 3(c)(1), pooled investment fund interests, a technical $0 minimum investment and $0 estimated sales commissions or finder's fees. Mare Liberum Critical Technologies Fund I GP, LLC is the General Partner; Mare Liberum Capital Partners, LLC is identified as the management company; and Erik Bethel, Marc Baliotti, Vrushank Vora and retired Rear Admiral Lorin Selby appear in the related-person chain. BHA Select Network, LLC, CRD 168883, is named in the sales-compensation section for solicitation in Florida, Massachusetts and New York even though the filing estimates commissions at $0. The fund also states that the management company will receive management fees based on securities sold. This is therefore not an anonymous defense-tech shell: the SEC issuer, management company, named principals and Mare Liberum's public maritime-investment platform all connect directly.
The distinctive story is Mare Liberum's decision to define critical technology through a specifically maritime lens. Its official site says the firm invests at the intersection of critical technologies and the maritime domain, focusing on autonomous systems, advanced manufacturing, electronic warfare, maritime intelligence, satellite connectivity, undersea infrastructure and technologies that protect global trade and national-security supply chains. Publicly displayed investments include Saronic Technologies for autonomous surface vessels, REGENT Craft for electric seagliders, Epirus for high-power microwave systems, Windward for maritime-domain intelligence and a stealth AI-infrastructure incubation. The platform's thesis is unusually coherent: instead of treating defense technology, shipping, subsea infrastructure and industrial resilience as separate themes, Mare Liberum treats oceans themselves as strategic infrastructure. That makes Critical Technologies Fund I materially different from a generic national-security VC vehicle.
THE UNIQUE STORY: PRIVATE CAPITAL IS BEING PAIRED WITH GOVERNMENT-BACKED SBICCT LEVERAGE
Mare Liberum also has a financing angle that very few recent Form D funds share. In March 2026 the firm announced that a second Mare Liberum fund had received a green-light letter connected to the U.S. Small Business Administration and the Department of Defense Office of Strategic Capital's SBIC Critical Technologies program, with potential access to as much as $150 million of low-cost government-guaranteed leverage. Mare Liberum said the capital was intended to support mission-critical technologies spanning AI, robotics, advanced manufacturing and autonomous systems. Fortune separately reported that the facility was structured as an up-to-$150 million loan and that access to the full amount was contingent on the fund raising substantial private LP capital. Investors should be careful, however, about legal-entity attribution: the public announcement refers to Mare Liberum's "second Fund," while the September SEC issuer is legally named Critical Technologies Fund I, LP, and Mare Liberum also has other 2026 critical-technology and advanced-manufacturing entities. The government-leverage program is therefore highly relevant to the platform's capital architecture, but investors should obtain the SBICCT licensing and fund-structure documents before assuming that every dollar of approved leverage belongs directly to this exact LP.
The team composition explains why Mare Liberum can credibly market a maritime-national-security specialty rather than simply adopt a defense-tech label. Erik Bethel previously worked in private equity, venture capital and investment banking at firms including J.P. Morgan, Morgan Stanley and Franklin Templeton, later served as U.S. Representative to the World Bank and was a partner at America's Frontier Fund. Marc Baliotti previously worked at AE Industrial Partners and GSO Capital Partners and has experience across aerospace, defense, credit and growth capital. Vrushank Vora's background includes microelectronics, AI and supply-chain technology investing, while Rear Admiral Lorin Selby served as the U.S. Navy's 26th Chief of Naval Research, overseeing approximately 3,800 personnel and a roughly $4 billion advanced-technology portfolio before retiring in 2023. Mare Liberum's advisory board also includes former Navy Secretary Kenneth Braithwaite, former NOAA administrator Timothy Gallaudet, former Deputy National Security Advisor Matthew Pottinger and former Federal Maritime Commission chairman Louis Sola. Those credentials do not establish Fund I returns, but they are directly relevant to sourcing, technical diligence, government procurement and the maritime-industrial ecosystem the fund targets.
FINAL ASSESSMENT
Mare Liberum Critical Technologies Fund I has one of the more differentiated profiles in this filing set because its SEC record can be tied to a narrowly defined maritime-critical-technology strategy, a team combining investing and senior naval experience, visible portfolio-company relationships and a separate government-backed SBICCT capital program at the broader platform level. The September filing confirms $25.8055 million sold to 17 investors only about two weeks after first sale, while Rule 506(c) permits general solicitation subject to accredited-investor verification. The key diligence issue is now legal and economic mapping: investors should determine how Critical Technologies Fund I, the separately filed Mare Liberum Critical Technologies Fund LLC, the Advanced Manufacturing Fund and the SBICCT-backed vehicle relate to one another; whether they share investments; how government leverage is allocated; what priority that leverage has relative to private LP equity; and how fees, carry and conflicts are handled across multiple Mare Liberum vehicles. The public evidence establishes a real and unusually specialized investment platform, but it does not establish current NAV, realized returns or that every public Mare Liberum portfolio company is held by this exact Fund I.

CORE INVESTOR QUESTIONS
How does Critical Technologies Fund I relate to Mare Liberum Critical Technologies Fund LLC | Which legal entity holds the SBICCT license or government-leverage entitlement | Has any of the up-to-$150M facility actually been drawn | What private LP equity must be raised before leverage becomes available | What interest rate, maturity and repayment priority apply to government leverage | Which public Mare Liberum investments are held specifically by Fund I | Are Saronic, REGENT, Epirus and Windward legacy or current Fund I positions | How are deals allocated among Critical Technologies Fund I, Critical Technologies Fund LLC and Advanced Manufacturing Fund | What management fee and carry apply | What GP commitment is required | What ownership and board rights does Mare Liberum seek | What percentage of Fund I can be concentrated in one company | How are export controls, ITAR, classified work and government-contract exposure handled | How are government procurement delays reflected in valuation

INDEPENDENT CONCLUSION
Mare Liberum Critical Technologies Fund I stands out because the manager has built an unusually narrow institutional thesis around maritime security rather than a generic defense-tech mandate. The September 2026 SEC filing verifies $25.8055 million sold to 17 investors under Rule 506(c), while the official platform shows investments across autonomous vessels, maritime AI, directed energy and electric seagliders and a team combining private-capital experience with senior U.S. naval and government backgrounds.
The most important unresolved issue is the fund map. Mare Liberum now has several similarly named critical-technology and advanced-manufacturing vehicles, while its broader platform has also been associated with an up-to-$150 million SBICCT leverage program. Investors should therefore verify precisely which entity owns which investments and which vehicle receives government-backed leverage before combining fundraising figures or attributing portfolio companies. Form D confirms the exempt offering; it does not mean that the SEC, SBA or Department of Defense approved the investment merits, valuation or future performance of Fund I.
