Starcloud is taking data centers off Earth and putting them into space.

To support this, the company announced a $250 million Series A extension funding round today. This brings the total raised to $450 million since they started in 2024. Now, the space startup is valued at $2.3 billion. The biggest investors are tech giants NVIDIA and Cisco Investments.

Starcloud has already shown that building data centers in space can work. Back in November 2025, they launched their Starcloud-1 satellite that housed an NVIDIA H100 GPU. They actually trained an AI model up there, ran a version of Google’s Gemini in orbit, and developed general procedures for operating high-performance GPUs in space.

“Last November, we put the first NVIDIA H100 in orbit. Today, this fresh capital empowers us to build the infrastructure to launch many more of NVIDIA’s most advanced GPUs into space,” said Philip Johnston, Co-Founder and CEO, Starcloud.

Starcloud and NVIDIA are now working together on the NVIDIA Space-1 Vera Rubin Module. It is built specifically for the extreme conditions of orbit. Cooling relies on large radiators, and the parts have to survive heavy radiation. Starcloud’s satellites will serve as early test platforms for these space-rated components.

The company wants a constellation of 88,000 satellites delivering 20 gigawatts of computing power. To get there, they are building a 100,000-square-foot manufacturing plant in Woodinville, Washington. This new facility will be used to build their next-generation Starcloud-3 spacecraft.

Cisco Joins the Mission

Adding Cisco brings networking, optical, and AI infrastructure expertise to the table.

“Cisco has long been a leader in secure data center infrastructure and looks forward to bringing that expertise to the emerging world of orbital data centers,” said Aleem Rizvon, vice president, Cisco Investments. “Cisco Investments is excited to invest in Starcloud as they expand data centers into space.”

The new funding will help Starcloud expand its manufacturing operations and continue its engineering work with NVIDIA. It will also help them buy future rocket launches to get their gear into orbit.
