Xona: What comes after GPS: Our $250M Series D

For decades, GPS has been one of the most important pieces of infrastructure in the world. It has given billions of people and devices a common understanding of where they are and what time it is, enabling everything from global commerce and transportation to communications networks and power grids to operate in synchronized harmony.

But the world we're building today looks very different from the one GPS was designed to support. Machines are becoming more autonomous, critical infrastructure is increasingly dependent on precise, trusted timing, and the limitations of today's navigation systems are becoming harder to work around.

We started Xona in 2019 because we believed the answer wasn't to simply recreate GPS with newer satellites, but to build something fundamentally better. Today, we're announcing $250 million in Series D funding at a $2.45 billion valuation, bringing the total capital we've raised to more than $570 million. The round is led by Steve Jurvetson's Future Ventures, with participation from new and existing investors. A longtime SpaceX board member, Jurvetson is an early backer of Xona and has previously backed SpaceX and Planet as they helped transform commercial launch and Earth observation.

This funding comes at an important inflection point for Xona. We've spent the last several years proving that a commercial company can build a fundamentally better satellite navigation system. Now we're moving from proving the technology to putting it into operation, with the capital, team and infrastructure to begin delivering service and rapidly scale toward global coverage.

From proving the technology to deploying the network

When we started Xona, satellite navigation was still a capability reserved almost exclusively for the world's largest governments. Traditional navigation spacecraft cost hundreds of millions of dollars, took years to develop and launch, and were designed for architectures that are difficult to improve once deployed. We believed that by moving navigation into Low Earth Orbit and rethinking the spacecraft, signal and ground systems together with a customer-first perspective, we could deliver dramatically better performance at a fraction of the cost.

Last year, Pulsar-0 gave us the opportunity to prove that architecture on orbit. Since then, we've conducted more than 500 transmissions, demonstrated positioning accuracy better than two centimeters, shown how much better Pulsar performs in challenging environments where traditional GNSS struggles, and proven that existing commercial receiver hardware can be upgraded to use our signal without physical modifications.

Earlier this week we launched six additional Pulsar satellites, beginning deployment of our commercial navigation network. Four of these spacecraft will begin providing service to customers in 2027. The other two are the first satellites designed and manufactured entirely in-house by our team in Burlingame, built around an architecture optimized for navigation performance and manufacturing at a cadence of multiple satellites per week.

Together, these spacecraft represent the beginning of a fundamental change in satellite navigation. We're beginning to deliver useful service to customers while simultaneously building the capability to manufacture, deploy and continuously improve the network as it grows. Navigation capabilities can no longer afford to evolve on the timescales of traditional government satellite programs. It needs to improve at the pace of the commercial users who depend on it, and this is exactly what we are delivering

Building for scale

Proving a new navigation architecture works is one challenge. Building hundreds of spacecraft, operating a global network and delivering a reliable service to billions of potential users is an entirely different one.

Over the past year, we've built out our spacecraft manufacturing capability at our now operational factory in Burlingame, expanded our manufacturing and operations footprint , and received first-of-its-kind FCC authorization for our commercial navigation constellation. We've also been growing the teams and systems required to move from individual technology demonstrations to repeatable production and service operations.

This new funding gives us the resources to accelerate that transition, scaling our manufacturing capacity, deploying more satellites, and investing in the systems required to operate Pulsar as a global service. It also gives us the ability to keep improving the technology as we deploy it. Our goal isn't to build a constellation that looks the same twenty years from now. Requirements will change, threats will evolve, and our users will need capabilities we can't fully predict today. Owning our technology and manufacturing processes gives us the control to respond to those changes directly, and to do so efficiently enough to keep the service accessible to users around the world.

Unlocking a new era

When combustion engines replaced horses, we didn't build mechanical horses. We built cars, and fundamentally changed what transportation could become. The same principle applies to navigation. The goal shouldn't be to replicate what GPS does today, but to enable what comes next.

Autonomous vehicles, robots, drones and other intelligent machines will need to operate and coordinate in ways that go far beyond human capabilities. That requires more than knowing approximately where something is. These systems will need precise, trusted positioning and ultimately a shared understanding of the physical world around them, including things they cannot directly see.

This is the foundation of the next generation of physical technology: a universal, real-time model of the world that enables machines to operate and coordinate with an entirely new level of precision and awareness. Pulsar is the first step toward making that possible, providing a common source of precise location and time that can be accessed by billions of existing devices today and the next generation of autonomous systems tomorrow.

We've made an incredible amount of progress since starting Xona solving challenges that most of the world told us was impossible. As we step into the next chapter of the company the "impossible" challenges are only going to grow. This makes them just that much more exciting to solve. If being part of a team that is hell-bent on solving "impossible" technology problems sounds exciting, we'd love to hear from you as we continue building the organization and infrastructure to deliver the global navigation service that the world needs today and will rely on in the future.

And ultimately, one that will enable technologies and capabilities we haven't even imagined yet.
