The Short Version
Every satellite has to talk to antennas on the ground, and there are far more satellites than there used to be: about 3,000 in 2020, and more than 14,000 by the end of 2025.
Northwood, a California startup, just raised $375 million to build a shared network of those ground antennas. Satellite owners can rent time on it instead of building their own, much as most people rent a hotel room rather than buy a house in every city they visit.
The company says it can open a new site in three months and switch on a new antenna within an afternoon of the truck arriving.
Northwood Space Corp., a Torrance, California company that builds and operates satellite ground stations, said on November 2, 2026 that it has closed a $375 million Series C equity round co-led by Andreessen Horowitz (a16z) and DFJ Growth, with participation from Alpine Space Ventures, Washington Harbour Partners, Stepstone Activate, In-Q-Tel and others. A separate multi-year credit facility from HSBC Innovation Banking, of undisclosed size, will support working capital and network expansion.
Northwood said that in the less than nine months since its Series B it has deployed six multi-orbit-capable sites on two continents, demonstrated command of a government geostationary satellite for the U.S. Space Force, launched a high-throughput dish called Prism, and opened a 185,000-square-foot headquarters and factory that expands its manufacturing footprint more than fivefold. It plans to add 400 jobs in Torrance and Washington, DC over three years and to announce further site expansions in the first half of 2027.
Executive Summary
Northwood is raising capital to sell satellite ground connectivity the way the terrestrial network industry sells interconnect capacity: the company owns the antennas, the sites and the scheduling software, and satellite operators book time on the shared network through an API rather than building dedicated ground stations of their own. The $375 million round, plus a bank credit facility, funds the hardware, factory output and site buildout that model depends on.
The announcement matters because the ground segment, the antennas and facilities that send commands up to satellites and bring their data down, has long been treated as bespoke, mission-specific construction. Northwood argues that satellite growth has outrun that model. Its own figures point to a sharp rise in active satellites, from about 3,000 in 2020 to more than 14,000 by the end of 2025.
What the company has shown is real but early: six sites, a Space Force prototype, a software technique that combines small antennas into larger ones, and a factory sized for hundreds of antennas a year. What it has not shown is how much of that capacity is under contract, at what prices, and how fully the shared sites are used. Those numbers will decide whether shared ground infrastructure is a better business than the dedicated stations it aims to replace.
From Owned Antennas to Booked Passes
The core of Northwood’s pitch is a change in who owns the ground station. Traditionally, a satellite operator that needed to reach its spacecraft built or leased a dedicated antenna site, often with significant civil works such as foundations, buildings and access roads. Northwood instead builds standardized, modular antennas in its own factory, ships them by ordinary freight, and installs them on sites that need, in its words, only flat ground, power and fiber. Operators then use a software interface to search, reserve, update and cancel passes, the windows of time when a satellite is overhead and in contact with a ground antenna.
For anyone who works in data centers or networking, the inputs are familiar: land, electricity and a fiber connection are the same three things that determine where a carrier hotel or edge facility can go. The operational consequence is that ground-station siting starts to look like a real-estate and connectivity problem that can be repeated, not a one-off engineering project. Northwood’s numbers back up the speed claim, at least so far: six sites in under nine months, a stated three months to stand up a new site, and three to four hours from truck arrival to a live link for a new antenna.
The beneficiaries of that model, if it works, are operators who would otherwise spend what Northwood describes as millions of dollars on dedicated stations, particularly newer constellation companies that would rather put capital into satellites than into antennas on the ground. The model also puts pressure on any provider whose pricing depends on long build times and scarce site availability. The trade-off for customers is the one familiar from any shared infrastructure: they give up exclusive control of the asset in exchange for lower upfront cost and faster access.
Capacity That Scales by Adding Units
Shared infrastructure only works if capacity can be added in small, predictable increments. Northwood’s answer is software arraying. The company says it combined 10 of its Portal phased-array antennas, flat panels that steer their beam electronically rather than by physically turning a dish, to match the receive performance of a 20-foot dish. If that holds up in operation, a site’s capability becomes a function of how many standard units are installed, much as a data hall’s compute grows by adding racks rather than by building a bigger mainframe.
Two caveats keep the result in proportion. The milestone as described concerns receive performance, not transmit, and the company has not published how arrayed performance holds up across different satellites, frequencies or weather conditions. The second product line, Prism, is a conventional parabolic dish built for multi-gigabit payload data, the imagery or communications traffic a satellite collects. Northwood’s goal of sites capable of more than 100 gigabits per second in high-demand regions by the end of 2027 is a target, not a delivered figure.
Manufacturing is the other half of the scaling story. The new 185,000-square-foot Torrance facility, opened in September 2026, is designed to produce hundreds of antennas a year at full production. Vertical integration, building the hardware, choosing and building the sites, and writing the scheduling software in-house, gives Northwood control of cost and deployment pace, but it also means the company carries the capital burden of every layer.
Government Demand as the Anchor
In infrastructure businesses, a large, creditworthy anchor customer often underwrites a buildout that is then sold to others. Northwood’s release places U.S. government and allied customers alongside commercial ones, and its most concrete operational milestone is government work: a Space Force prototype that delivered satellite command capacity as a service to geostationary orbit, the high orbit roughly 36,000 kilometers up where satellites appear fixed over one spot on Earth. The demonstration included a full-duplex link, meaning simultaneous two-way communication, to a government satellite from a Portal site, building on earlier demonstrations with satellites in low Earth orbit, which circle only a few hundred to roughly 2,000 kilometers up.
The investor list points the same way. In-Q-Tel is the not-for-profit strategic investor that backs technology of interest to the U.S. intelligence and national security community, and Northwood plans to add jobs in Washington, DC as well as Torrance. Multi-orbit capability matters here because defense users increasingly operate satellites in several orbits at once and want one ground network that can reach all of them.
The tension in this anchor is that national security customers typically demand assurance, isolation and priority access, while a shared network earns its economics by spreading capacity across many users. How Northwood reconciles those requirements, through dedicated antennas within shared sites, priority scheduling or direct hardware sales, which it offers to select customers, is likely to shape both its margins and its appeal to commercial operators.
What the Shared Model Still Has to Prove
The financial logic of shared infrastructure is utilization. A ground site that is booked for a large share of its available passes can undercut a dedicated station on price; a site that sits idle is simply a more distributed version of the same capital expense. The release reports new customers and contracts across government agencies, newer commercial operators and traditional satellite operators, but gives no count, no contract values and no utilization figures, so the economics cannot yet be assessed from outside.
The capital structure is consistent with a hardware-heavy buildout. Pairing a large equity round with a multi-year bank credit facility for working capital and expansion is a common pattern for companies that must manufacture equipment and deploy sites ahead of revenue. The size and terms of the HSBC facility were not disclosed.
Some claims in the announcement deserve to be read as opinion until data supports them. An investor quoted in the release says Northwood has quickly surpassed legacy incumbents; the release does not provide comparative figures on sites, capacity, customers or revenue that would substantiate that comparison. Established providers, including large cloud companies such as Amazon Web Services, already rent antenna time to satellite operators, so Northwood’s differentiation will rest on deployment speed, multi-orbit reach and price, all of which the market will test as the network grows.
Background
Northwood Space is a Torrance, California company co-founded by CEO Bridgit Mendler that builds modular antenna hardware, manufactures it in-house, and operates it as a shared ground network for commercial, U.S. government and allied satellite operators. Andreessen Horowitz has invested in every round since the company’s seed financing, and the Series C follows a Series B raised less than nine months earlier.
The satellite ground segment, the antennas, sites and software that connect spacecraft to terrestrial networks, has historically been built mission by mission, often with long construction timelines. The rapid growth of satellite constellations, particularly in low Earth orbit, has pushed operators toward ground-station-as-a-service models in which a provider owns the antennas and customers pay for contact time. Northwood is one of several companies pursuing that model, distinguishing itself on multi-orbit capability, vertically integrated manufacturing and deployment speed.
