Northwood Space raises $30M Series A to build shared ground station infrastructure for the satellite economy
Apr 23, 2025 with Bridgit Mendler
Key Points
- Northwood Space raises $30 million Series A led by Andreessen Horowitz to build shared ground station infrastructure for satellite operators, targeting 500 sites near-term.
- Most satellite operators today either book antenna time individually or build proprietary ground networks, leaving expensive hardware vulnerable to communication failures that can last hours or days.
- Shared ground infrastructure modeled on SpaceX's Starlink approach would enable use cases like disaster response, where satellites could assess wildfires in real time if the network could support the data throughput.
Summary
Bridgit Mendler's Northwood Space is building shared ground station infrastructure for the satellite industry — the communication layer that lets operators actually use their hardware once it's in orbit. The company just closed a $30 million Series A led by Andreessen Horowitz, with Founders Fund among the co-investors.
The pitch is straightforward: rockets get things into space, satellites are the things that go up, but the ground network is what makes them useful. Right now, most satellite operators either book antenna time individually — think scheduling a science telescope — or try to build their own ground infrastructure. Neither scales. Northwood's co-founder experienced this firsthand: during a single overnight shift at a prior company, four separate ground station failures occurred across different sites, including one that had already gone dark without notifying anyone. A customer Mendler spoke to last week had been out of contact with its satellite for 28 hours. Given that a satellite can cost tens or hundreds of millions of dollars, that is a material operational risk.
Mendler draws the analogy to internet routing — the goal is for operators to trust the network to deliver, rather than managing every individual antenna and booking. SpaceX's Starlink is the benchmark: hundreds of ground stations providing both global coverage and regional density to support millions of users. Northwood wants to offer that same infrastructure as a shared service. The near-term target is 500 sites.
The enabling use case Mendler flags is disaster response. During the LA wildfires earlier this year, helicopters couldn't safely enter burn zones to assess fire direction and scale. Satellites with sufficient revisit rates — the frequency with which they pass over a given region — could fill that gap, but only if the ground network can support the data throughput. That kind of application, she argues, would have been impractical to build without SpaceX-scale resources five years ago. Shared infrastructure changes that calculus.
