INDEPENDENT ASSESSMENT
ISQ Global InfraTech Fund II, L.P. is a verifiable 2024 Cayman Islands pooled investment fund managed through I Squared Capital's Miami infrastructure platform. Its September 14, 2026 SEC Form D/A reports an indefinite offering with $30,000,000 sold to two investors, a first sale on April 22, 2026, Rule 506(b), Section 3(c)(7), equity and pooled investment fund interests, no outside placement agent, $0 sales commissions and $0 finder's fees. ISQ Global InfraTech Fund II GP, LLC is the General Partner, I Squared Capital Advisors (US) LLC is explicitly identified as Investment Manager, and I Squared co-founders Sadek Wahba and Gautam Bhandari appear as executive officers; Bhandari signed the amendment as manager of the sole member of the General Partner. The filing also states that confidential offering materials describe fees payable to the Investment Manager and General Partner. The most important point is that the $30 million figure is cumulative securities sold by this legal vehicle, not the size of I Squared's entire InfraTech strategy and certainly not I Squared's firmwide AUM. The real research story is how a global infrastructure manager is using a dedicated technology fund to invest in companies whose software, AI, satellites, energy systems and industrial technology increasingly behave like infrastructure.
The chronology makes Fund II particularly interesting. I Squared filed the original Form D in August 2025 when the vehicle still showed $0 sold, while the 2026 amendment now records a first sale in April and $30 million subscribed by only two investors. That is a very concentrated early fundraising profile, but it sits inside a manager with far greater institutional scale: an April 2026 public-pension presentation described I Squared as an independently owned infrastructure manager founded in 2012 with more than 300 global investors and approximately $55 billion of AUM as of September 30, 2025. That $55 billion includes multiple infrastructure, growth-markets, credit, InfraTech, energy-transition and co-investment vehicles and should never be presented as Fund II NAV. The contrast is precisely what makes this filing useful: a very small reported Fund II investor base is being launched inside a mature multi-strategy infrastructure organization, so investor diligence should focus on whether the two early LPs are seed institutions, affiliated entities, strategic cornerstone investors or simply the first closings in a much broader fundraising process.
THE UNIQUE STORY: I SQUARED IS TREATING "PHYSICAL AI" AS INFRASTRUCTURE RATHER THAN ORDINARY VENTURE CAPITAL
I Squared's current InfraTech materials define the strategy around growth-stage technology companies that improve the intelligence, resilience and performance of physical infrastructure. The clearest 2026 example is Muon Space: in August, InfraTech participated in the company's oversubscribed $250 million Series C. Muon designs, manufactures and operates complete low-Earth-orbit satellite constellations, and I Squared explicitly argued that its multi-year customer programs, recurring operations revenue, high upfront capital intensity and mission-critical services increasingly resemble the economics of fiber networks, towers and other traditional infrastructure. Muon had deployed 11 satellites across six launches, had more than 50 additional satellites in development and opened a manufacturing facility designed for up to 500 satellites annually by 2027. I Squared also lists other InfraTech investments such as Tomorrow.io, CheckSammy and Fermata Energy, showing that the strategy spans weather intelligence, waste/recycling infrastructure and vehicle-to-grid technology rather than conventional enterprise software alone. This is a genuinely different investment thesis: Fund II sits at the boundary where growth equity, industrial technology and infrastructure ownership increasingly converge.
That thesis also creates unusual allocation questions because I Squared simultaneously operates flagship infrastructure funds, energy-transition strategies, growth-markets funds, credit funds and dedicated co-invest vehicles. A technology company can potentially touch several of those mandates: data-center software may support physical data-center assets, grid technology may overlap with energy-transition investments, and satellite data may serve utilities, transport and logistics businesses already owned elsewhere in the platform. Public records show I Squared was also launching a U.S. AI-inference and edge-colocation data-center platform called Saragon in August 2026 with up to $1 billion of backing, while InfraTech was investing in Muon around the same period. Those transactions should not automatically be attributed to Fund II, but they demonstrate why the Fund II LPA and allocation policy matter. Investors should understand when an opportunity belongs to InfraTech Fund II, a flagship infrastructure fund, an energy-transition vehicle, a co-investment sleeve or a direct platform investment, and how conflicts are resolved if more than one I Squared strategy could reasonably own the same exposure.
FINAL ASSESSMENT
ISQ Global InfraTech Fund II has a strong regulatory and sponsor-verification profile but remains relatively early in its publicly visible fundraising cycle. The September 2026 SEC amendment confirms $30 million sold to two investors, while the manager is part of a roughly $55 billion global infrastructure organization with a broad institutional LP base. What differentiates Fund II from a normal growth-equity fund is I Squared's attempt to identify technology businesses whose economics increasingly resemble infrastructure — recurring services, high switching costs, long-duration customer relationships and direct relevance to power, transport, communications, logistics and physical systems. Muon Space is the clearest current illustration of that thesis, but investors should not assume every publicly listed InfraTech company belongs specifically to Fund II without fund-level attribution. The decisive diligence documents are the current commitment schedule, portfolio allocation, fee and carry terms, Fund I performance, ownership and follow-on policy, cross-fund allocation rules and the list of investments actually held by Fund II.

CORE RISKS
Growth-stage technology valuation risk | hardware execution risk | capital intensity | AI infrastructure cyclicality | satellite and aerospace execution risk | government procurement exposure | energy-policy and regulatory risk | follow-on financing risk | cross-fund allocation conflicts | concentration from a small early LP base | private-company illiquidity | long realization periods | Fund II-specific portfolio not publicly disclosed | $55B firmwide AUM should not be confused with Fund II assets | company financing-round sizes do not equal I Squared investment amounts.
INDEPENDENT CONCLUSION
ISQ Global InfraTech Fund II is a useful example of how infrastructure investing is expanding beyond roads, power plants and data centers into the technology layers that increasingly control those systems. The SEC filing establishes a real Fund II vehicle with $30 million sold to two investors, while I Squared's current investment activity shows the InfraTech strategy moving into satellite constellations, grid technology, weather intelligence and other physical-AI applications.
The distinctive diligence question is allocation, not basic legitimacy. I Squared now has enough infrastructure, energy-transition, credit and technology strategies that a single company can potentially fit more than one mandate. Investors should therefore verify Fund II's exact portfolio, current commitment level, Fund I track record and cross-fund allocation policy before assuming that every public InfraTech investment belongs to this particular legal vehicle. Form D verifies the exempt offering; it does not mean that the SEC approved Fund II, I Squared Capital, Muon Space, any technology valuation or future investment performance.
