Northwood Space closed $375 million Series C at $2 billion valuation

Northwood Space closed a $375 million Series C equity round at a $2 billion valuation on Nov. 2, 2026, bringing total capital raised to over $500 million.

Andreessen Horowitz and DFJ Growth co-led the financing. Participants include Alpine Space Ventures, Washington Harbour Partners, Stepstone Activate, In-Q-Tel and others. HSBC Innovation Banking provided a separate multi-year credit facility to Northwood, with the value not disclosed. Katherine Boyle said, “We’ve backed Northwood in every round since seed because we believe ground infrastructure is essential to making space infrastructure more abundant.”

The Series C follows Northwood’s $100 million Series B by less than nine months. Washington Harbour Partners led that earlier round, with Andreessen Horowitz as co-leader and participation from Alpine Space Ventures, Founders Fund, Stepstone, Balerion, Fulcrum, Pax, 137 Ventures and others, according to Northwood’s March 2026 blog post. Katherine Boyle said, “The team brings rare technical depth across hardware, software, and national security programs.”

Northwood designs and manufactures modular antennas in Torrance, California. Portal phased arrays support command and control, and Prism high-throughput dishes carry payload data. Portal is a multibeam phased array system supporting connections across LEO, MEO and GEO — low Earth orbit, medium Earth orbit and geostationary orbit — with electronically steered beams in real time. The company unveiled Prism in June 2026 as a parabolic dish designed for multi-gigabit links.

Northwood arrayed 10 Portal ground antennas to achieve the same performance as a 20-foot dish. Live tests showed command capacity from geosynchronous orbit using a commercial phased array. Northwood demonstrated capability spanning LEO to GEO in a U.S. Space Force prototype, with dedicated satellite command capacity provided to geostationary orbit as a service.

Northwood supports satellite links through an API, or application programming interface, letting satellite operators quickly reserve capacity. Its software combines antennas into larger effective apertures, and the API lets operators search, reserve, update, and cancel passes, guided by Mission Architects.

Northwood hardware can be packed into standard freight containers, shipped worldwide, and turned on hours after arriving. The company can build hundreds of antennas per year at full production, and shipping each system by standard freight needs only flat ground, power and fiber. Building a new site takes three months instead of years, and antennas arrive by truck and reach live links within three to four hours.

Since its Series B, Northwood deployed six multi-orbit-capable sites on two continents. Two sites stood ready for operations, five were in build and eight were in progress across five continents when the Series B was announced. Northwood sells its antenna systems directly to select customers, using the same hardware that powers the shared network.

Payload and Venture Capital Tracker date the opening of Northwood’s 185,000-square-foot Torrance, California facility to August 2026, while Northwood’s PR Newswire release dates it to September 2026. Annually on dedicated production lines, the headquarters and factory will output hundreds of antennas along with other components.

Northwood now has more than 140 employees and intends to add 400 jobs spanning Torrance and Washington, DC across three years in RF engineering, manufacturing, software and site operations. Bridgit Mendler said Northwood plans to reach and surpass the hundreds of sites operated by today’s largest ground networks, adding, “We plan to reach that and surpass that.”

Northwood secured a three-year $49.8 million contract with the U.S. Space Force in January 2026 to support the military’s Satellite Control Network. The company achieved a three-month turnaround from contract execution with the Space Force to communication links ready for operations. Payload says Northwood has been delivering GEO ground links under the deal.

Active satellites grew from about 3,000 in 2020 to more than 14,000 by the end of 2025, with tens of thousands more projected by 2030. Northwood aims to standardize the entire network stack around ground stations so companies and defense users can benefit from shared, expandable infrastructure.

Prism and Portal will support global coverage, with sites capable of 100+ Gbps in high-demand regions by the end of 2027. Northwood plans site and network expansions for announcement during the first half of 2027. The Series C funds will expand Northwood’s team and deploy antennas at more ground stations worldwide.

Northwood’s first Portal iteration successfully ran TT&C, or tracking, telemetry and command, operations with Planet Labs in October 2024. In June 2025, the company demonstrated a second, higher-power Portal iteration delivering one kilowatt of transmit power and receiving sub-picowatt signals within the same face. In December 2025, Northwood hit production volume of eight Portal units in a single month, building and testing eight full arrays within four weeks.

As of January 2026, Northwood deployed operational Portal units across two continents. At the latest site, arrays were installed and powered in 12 hours, and live contacts began the next day. By end of 2026, Northwood will have capacity to consistently produce over a dozen Portal arrays per month and targets over 82 beams ready for operations across 18 global ground sites.

Northwood designed its technology to deploy quickly, offer greater data links, and use a smaller physical footprint than traditional ground station hardware. Northwood standardizes antennas and makes them modular, so ground sites can expand quickly when capacity needs grow.
