INDEPENDENT ASSESSMENT
Mare Liberum Critical Technologies Fund I, LP is a verifiable 2025 Delaware pooled investment fund whose September 15, 2026 SEC Form D reports an indefinite offering with $25,805,500 sold to 17 investors after a first sale on August 31, 2026. The fund relies on Rule 506(c) and Section 3(c)(1), offers pooled investment fund interests, reports a technical $0 minimum investment, $0 estimated sales commissions and $0 finder's fees, and states that its management company will receive management fees based on the amount of securities sold. 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, Rear Admiral Lorin Selby and Vrushank Vora appear in the related-person chain. BHA Select Network, LLC, CRD 168883, is listed as a sales-compensation recipient for solicitation in Florida, Massachusetts and New York even though Item 15 currently estimates $0 commissions. The unusual part is not simply that this is another defense-tech fund; Mare Liberum has built a narrow thesis around the maritime domain, where autonomous vessels, subsea systems, satellite connectivity, naval modernization, shipbuilding and maritime AI are treated as critical infrastructure rather than as isolated venture categories.
The fund's legal structure is only one part of a rapidly expanding Mare Liberum capital stack. A separate Mare Liberum Critical Technologies Fund LLC filed in July 2026 with a fixed $150 million offering and reported $60.35 million sold to 10 investors under Rule 506(b), while Mare Liberum Advanced Manufacturing Fund LLC filed in August and was later amended in September with a $15 million offering. That means the sponsor is not operating one single flagship vehicle; it is building multiple related sleeves around critical technologies, advanced manufacturing and maritime-security exposure. The September Fund I filing is also legally distinct from the earlier $150 million Critical Technologies Fund LLC: different issuer, different CIK, different exemption and different investor count. FilingDossier should therefore avoid adding $25.81 million, $60.35 million and the Advanced Manufacturing fund's amounts into one synthetic AUM number without the manager's organizational chart. The more useful question is why the sponsor is separating exposures across a 3(c)(1) Rule 506(c) Fund I, a separate Rule 506(b) Critical Technologies LLC and an Advanced Manufacturing sleeve, and whether those vehicles invest pari passu, target different investor groups or hold different asset pools.
THE UNIQUE STORY: MARE LIBERUM IS BUILDING A MARITIME-SPECIFIC DEFENSE TECHNOLOGY PLATFORM, NOT A GENERIC DUAL-USE FUND
Mare Liberum's official website is unusually explicit about what it believes the market is missing. The firm says it invests at the intersection of critical technologies and the maritime domain, arguing that oceans are infrastructure because they support global trade, energy flows, undersea communications and national security. Its thesis is organized around three structural shifts: emerging ocean platforms such as deep-sea exploration and satellite-linked maritime systems; national-security modernization through low-cost unmanned maritime platforms; and global trade realignment away from China. The portfolio examples reinforce that narrow focus: Saronic Technologies for autonomous surface vessels, REGENT Craft for electric seagliders, Epirus for directed-energy electronic warfare, Windward for maritime-domain awareness, and a stealth AI-data-center investment tied to sovereign national-security infrastructure. This is materially different from a broad defense-tech fund that happens to own one naval company. Mare Liberum's entire brand, advisory board and investment thesis are built around preserving freedom of the seas and modernizing maritime capabilities.
The leadership and advisory network deepen that specialization. Mare Liberum lists Marc Baliotti, Erik Bethel, Rear Admiral Lorin Selby and Vrushank Vora as General Partners, while its Board of Advisors includes former U.S. Secretary of the Navy Kenneth Braithwaite, former State Department Undersecretary Paula Dobriansky, former NOAA Administrator and U.S. Navy Chief Oceanographer Timothy Gallaudet, gCaptain founder John Konrad, former Deputy National Security Advisor Matthew Pottinger and former Federal Maritime Commission Chairman Louis Sola. That network does not guarantee returns or government contracts, but it is unusually aligned with the fund's stated domain. It also creates a distinctive diligence issue: investors should understand how the fund manages potential conflicts, information boundaries and government-related relationships when backing companies that may sell to the U.S. Navy, allied militaries, ports, shipyards or national-security agencies. The firm's website also states that Mare Liberum is SEC-registered, while explicitly noting that registration does not imply skill or approval; investors should verify the current adviser entity and Form ADV directly rather than rely only on the website statement.
FINAL ASSESSMENT
Mare Liberum Critical Technologies Fund I has a strong legal and thematic verification profile, but its real differentiation is the sponsor's decision to define maritime security as a standalone private-capital category. The SEC filing confirms $25.8055 million sold to 17 investors, Rule 506(c), Section 3(c)(1), the Mare Liberum management chain and an institutional distribution relationship with BHA Select Network. The broader public evidence shows a fund platform expanding across critical technologies and advanced manufacturing while maintaining a highly specific maritime thesis built around autonomous vessels, shipbuilding, subsea systems, satellite connectivity, electronic warfare and sovereign infrastructure. The central diligence questions are therefore fund allocation, vehicle overlap, government-customer concentration, technology-development risk and how the sponsor separates the new Fund I from its related $150 million Critical Technologies Fund LLC and Advanced Manufacturing Fund. Form D verifies the offering; it does not establish current NAV, portfolio attribution, contract backlog or future investment performance.

CORE INVESTOR QUESTIONS
Why is Fund I structured under Rule 506(c) and 3(c)(1) while the related $150M Critical Technologies Fund LLC uses Rule 506(b) | Do the vehicles invest in the same companies or different opportunity sets | Which Saronic, REGENT, Epirus, Windward or other positions belong specifically to Fund I | What current NAV corresponds to the $25.8055M of securities sold | What management fee and carry apply | What percentage of capital may be invested in one defense or maritime company | How much exposure is dependent on U.S. government procurement | How are opportunities allocated between Critical Technologies Fund I, the separate Critical Technologies LLC and Advanced Manufacturing Fund | Are government-contract rights, export controls or classified work material to portfolio value | What liquidity and follow-on reserve policies apply | What role does BHA Select Network play in the ongoing raise | Are any advisory-board members compensated by the fund or portfolio companies
CORE RISKS
Defense-procurement risk | government-budget dependence | export-control and ITAR risk | hardware and manufacturing execution | long procurement cycles | early-stage technology risk | maritime-market concentration | autonomous-system regulatory risk | geopolitical sensitivity | cross-fund allocation conflicts | portfolio-company capital intensity | small investor base | management-fee terms not public | Form D sales do not equal current NAV | manager-level portfolio names should not be assumed to belong to Fund I.
INDEPENDENT CONCLUSION
Mare Liberum Critical Technologies Fund I is not simply another dual-use technology fund. Its defining feature is a narrow thesis that treats oceans, naval systems, undersea connectivity and maritime trade infrastructure as one integrated strategic market. The SEC filing verifies $25.8055 million sold to 17 investors and a real management structure, while the official portfolio and advisory network show unusually deep alignment with maritime security and national-security modernization.
The main diligence issue is now vehicle architecture. Mare Liberum has multiple 2026 funds with different exemptions, sizes and legal structures, so investors need to know exactly which assets sit in Fund I and how opportunities are divided across related vehicles. The manager's maritime thesis is highly differentiated; the public record still does not establish Fund I-specific NAV, portfolio attribution, fee terms or realized performance.
