Northwood Space’s Bridgit Mendler says ground infrastructure unlocks space economics now

Northwood Space CEO Bridgit Mendler is making a blunt point at Fortune Brainstorm Tech conference in Aspen, Colorado on Tuesday: the “space economy’s next frontier” is not another satellite or rocket. It is the ground infrastructure that links Earth to space, and she says the economics are switching in a way that could pull major parts of the economy into orbit.

Mendler argues that the industry has moved from niche projects into an adoption curve that looks a lot like telecom, because satellites are no longer isolated missions. They are evolving into large constellations of thousands, which means they need network routing, not just hardware. Without that infrastructure, she described a satellites as a “really expensive hump of metal up in space.” In plain terms: you can launch the satellites, but you still need the Earth side to make the network work like a real service, not a science experiment.

That shift is happening fast because two other pieces are scaling up simultaneously. Mendler pointed to massive leaps in launch capacity and spacecraft manufacturing, which are supercharging the space economy by making it cheaper and faster to build and deploy satellites. The result is a boom in low-Earth orbit systems, where global connectivity, sensing, and potentially compute workloads are all chasing throughput.

The competitive landscape is already shaped by this throughput race. SpaceX’s Starlink currently has more than 10,000 operational satellites in low-Earth orbit, while Amazon’s Project Kuiper is racing to launch its own constellation of satellites. Beyond connectivity, companies also hope to eventually launch so-called orbital compute data centers, and the deals reflect that ambition. Fortune’s coverage notes that companies are striking massive multi-billion-dollar deals to deliver AI compute services via space infrastructure. If you zoom out, the common denominator across all of these use cases is data movement. Mendler’s framing is that data is the way that you gather value from the space economy, and the more throughput you can get through space, the space economy directly grows.

Northwood’s thesis is that the missing throughput lever is on Earth. The company is focused on the ground segment, which Mendler described as the networking system linking Earth and space. Her flagship product, Portal, uses a network of smaller individual antennas that work together as a single powerful system designed to replace traditional parabolic dishes. That architecture matters because ground infrastructure is often where operational complexity and costs pile up when you scale from a few missions to thousands of spacecraft. A shared, distributed antenna network can be more adaptable as constellation size grows, and Mendler explicitly positions this as a shared resource.

Her “shared layer” analogy is cloud infrastructure for startups. Mendler’s philosophy is that space networking should be a shared resource, and that providing this layer could drastically shorten the timeline for new space ventures. She also made a time claim during the conference, saying what took industry leaders like SpaceX 20 years to build could soon be achieved in five. Whether or not an individual project hits that exact timeline, the strategic takeaway is that the bottleneck is shifting. If ground networking becomes standardized and widely available, more players can run experiments, launch services, and scale without rebuilding Earth-side infrastructure from scratch.

Capital markets are reinforcing the timing. Northwood recently closed a $100 million Series B funding round led by Washington Harbour Partners and Andreessen Horowitz, signaling investor appetite for the Earth network layer at the same time satellite constellations and launch capacity are accelerating. And the broader space market is poised for additional attention this week, when SpaceX is expected to make its public market debut under the ticker SPCX at a $1.75 trillion valuation. Fortune reports the IPO is expected to raise $75 billion, which would make it the largest IPO in history, surpassing Saudi Aramco’s 2019 debut. Even if you are not directly investing in IPO shares, that kind of spotlight tends to pull more capital, partnerships, and talent into the entire stack, including ground infrastructure.

There is also a human and cultural angle to how Mendler frames her leadership. She is a former Disney Channel actress who appeared in popular TV shows such as Good Luck Charlie and Wizards of Waverly Place. She told the conference she views her Hollywood background as “traditional” for a space CEO because both industries require high risk tolerance and the ability to beat significant odds. While that is not a technical argument, it maps to the operational reality she is describing: in a world where thousands of satellites require reliable routing and throughput, the winners are the teams that can execute under uncertainty, build infrastructure that scales, and make adoption repeatable.

For executives, the second-order implication is that “space” is no longer a monolithic bet. It is a systems bet spanning launch, manufacturing, ground networking, and the software that makes it all usable. Mendler’s core claim is that the economics switching point is driving adoption and market share from major parts of the economy like telecom. If she is right, boards and leadership teams should treat ground infrastructure like a platform category, not an afterthought. The company that owns the shared routing layer, the interoperability story, and the throughput experience could become as strategically important to the space economy as the satellites themselves.
