InfiniG Raises $5.2M to Scale Indoor Cellular Coverage

InfiniG has raised $5.2M in Seed funding to expand Mobile Coverage as a Service, its fully managed platform for multi-operator cellular coverage inside enterprise buildings and campuses. The round was co-led by J2 Ventures and Stormbreaker Ventures, according to InfiniG’s official announcement on August 18, 2026.

The financing matters because indoor mobile coverage still behaves like an exception project in a world that treats connectivity as essential infrastructure. Offices, hotels, hospitals, schools, warehouses, and mixed-use properties can have excellent Wi-Fi while cellular calls and data fail behind concrete, steel, low-emissivity glass, elevators, and underground spaces.

InfiniG’s argument is straightforward: enterprises should be able to procure indoor cellular the way they buy other managed infrastructure. One neutral-host system can support multiple mobile operators, preserve the phones and plans people already use, and give property teams a repeatable model across one building or an entire portfolio.

What InfiniG Announced

The $5.2M Seed was co-led by J2 Ventures and Stormbreaker Ventures. InfiniG said the capital will help scale its Mobile Coverage as a Service platform and bring reliable multi-operator coverage to more enterprise buildings and campuses. The company did not disclose its valuation, security type, full investor syndicate, prior-round totals, or total funding to date.

That disclosure boundary is important. A secondary funding database lists an earlier unattributed investment involving J2 Ventures, but the amount and relationship to the newly announced Seed are unclear. The verified story is the current $5.2M round, the two named co-leads, and the company’s stated expansion plan.

J2 Ventures and Stormbreaker Ventures both already list InfiniG in their official portfolios. J2 places the company within infrastructure, while Stormbreaker categorizes it within private networks and Open RAN. The overlap is not cosmetic: both firms invest around the physical and software layers that let modern applications connect to the real world.

How Mobile Coverage as a Service Works

InfiniG describes MCaaS as a fully managed, cloud-based neutral-host service. The company coordinates mobile-operator onboarding, network integration, emergency-calling support, monitoring, analytics, operations, and ongoing service. Users do not need to change phones, SIM cards, mobile plans, or normal behavior.

The architecture uses shared CBRS spectrum and common infrastructure to support multiple mobile operators. That model targets a stubborn gap between traditional distributed antenna systems, carrier-funded projects reserved for the largest venues, signal repeaters that depend on outdoor coverage, and Wi-Fi calling that shifts part of the reliability burden onto users and local networks.

InfiniG says its systems now cover more than 10M square feet across the United States. That is a company-reported metric, not an independently audited figure, but it indicates the company has moved beyond a laboratory concept. Current company materials describe use across offices, hospitality properties, hospitals, schools, warehouses, campuses, and other enterprise settings.

Why the Founders Built InfiniG

Joel Lindholm, co-founder and CEO, and Fuad Abdelaziz, co-founder and CTO, worked together at Meta before starting InfiniG. The company says they helped design and deploy shared-spectrum indoor cellular infrastructure across Meta’s U.S. campuses, where a practical constraint was impossible to ignore: employees arrived with different carriers, but every phone still needed to work.

That experience shaped both the technology and the business model. Lindholm and Abdelaziz saw that shared neutral-host infrastructure could deliver multi-operator coverage, but the traditional carrier-funded deployment model could not economically reach the broad range of enterprise properties that needed it. InfiniG was created to make the model repeatable and manageable for the enterprise buyer.

The current leadership team also includes Kishore Raja as Chief Cloud and AI Officer, Debra Bradley as CFO, Juan Santiago as VP of Product, and Tom Williams as VP of Global Sales and Business Development. Their backgrounds span wireless networks, cloud systems, carrier sales, private networking, AI, product, and financial operations.

Why This Round Matters

The immediate use case is simple: better indoor calls and mobile data. The strategic value extends further. Reliable multi-operator cellular supports emergency communications, property operations, connected devices, private networks, automation, and physical-AI systems that depend on consistent connectivity outside the tidy boundaries of a Wi-Fi network.

Enterprise ownership is the larger market signal. Property teams increasingly control power, security, access, Wi-Fi, cloud applications, sensors, and operational data, yet indoor cellular has often remained outside that operating model. MCaaS brings cellular closer to the managed-service structure enterprises already understand, with one accountable provider and a common deployment pattern.

That shift also changes how coverage can scale. A one-off project solves one building; a managed platform can create standards across a portfolio. If InfiniG can preserve carrier-grade reliability while simplifying procurement, operations, and expansion, the value is not only better signal strength. It is a new control layer for enterprise connectivity.

The Bigger Infrastructure Shift

The round arrives as the boundary between enterprise networks and mobile-operator infrastructure is becoming more flexible. CBRS opened shared spectrum to new deployment models, cloud management made distributed networks easier to operate, and private wireless created demand for cellular systems designed around enterprise requirements.

InfiniG positions MCaaS as a foundation that can evolve from LTE toward 5G, private networks, analytics, automation, and physical AI. The company is not promising every future workload today. It is arguing that enterprises need indoor cellular infrastructure that can adapt without forcing a complete rebuild each time network requirements change.

That is the bet J2 Ventures and Stormbreaker Ventures are backing with this Seed. The companies building intelligent properties, automated facilities, and connected operations still depend on an older promise that has never become less important: when people walk inside, their phones should continue to work.
