Space networking firm Aalyria has raised $100 million in a Series B round, valuing the Google spin-out at $1.3 billion.

Aalyria is the developer of Tightbeam, ultra-high-speed laser terminals that enable communication between satellites. The company has also built Spacetime, a platform to manage these connections. The firm intends to use the funding to expand the deployment of its products.

The Series B round was led by Battery Ventures and J2 Ventures, with support from DYNE and other investors.

Founded in 2021, Aalyria is a company Google spun out after it decided to shutter its Loon project, a scheme that would’ve seen Internet connectivity delivered wirelessly via a network of balloons. Its technology is based on a decade of research carried out by the search giant and at the Lawrence Livermore National Laboratory, a US federal science and technology research institute.

"We started Aalyria to build what space has been missing: a true communications and networking layer that scales with human and market demand," said CEO Chris Taylor. "Every major infrastructure shift - from railroads to telecommunications to the Internet - required a control plane that could coordinate complexity at scale. Space is no different - nor are the varied businesses and missions that space serves.

“This funding accelerates our path to becoming that ubiquitous control plane: the digital cartilage that connects thousands of independent satellites, aircraft, ships, fiber, and ground stations into a single, intelligent network that can route around failures, optimize for mission priorities, and adapt in real-time. We're not just connecting space systems - we're making space infrastructure as reliable and programmable as the Internet itself.”

Aalyria says it works with commercial and government clients, and that its laser-based network can deliver data faster than terrestrial rivals. It says its systems are already being deployed in support of commercial satellite programs, including next-generation low Earth orbit constellations, as well as missions for the US Government and its allies.

“Aalyria has built an extremely important platform at the intersection of advanced networking, AI-driven orchestration, and national security,” said Michael Brown, general partner at Battery Ventures and incoming board member at Aalyria. “The team’s ability to deliver resilient, software-defined connectivity across complex environments positions the company to play a foundational role in next-generation communications architectures.”
