These startups are building data centers in satellites orbiting the Earth.
1
Rotonium
Country: Italy | Funding: €1M
Rotonium is a deep technology business that focuses on the development of scalable and minuscule quantum computers at room temperature.
2
Starcloud
Country: USA | Funding: $203M
Starcloud offers cloud computing and data relay to satellites in space. The company has already launched a satellite with an Nvidia H100 GPU into orbit, becoming the first to launch a LLM on a powerful Nvidia GPU beyond Earth. The satellite also carries Gemma, Google's open source large-scale language model. This makes it the world's first data center for AI in space.
3
Aetherflux
Country: USA | Funding: $50M
Aetherflux is building a constellation of small LEO satellites to beam solar energy to Earth using infrared lasers. This approach differs from traditional space-based solar power (SBSP) concepts, which rely on massive geostationary platforms transmitting power via microwaves. The US Defense Department has allocated funding for the development of this technology to ensure the energy supply to remote military bases and contested areas. Additionally, the Aetherflux satellites will have an orbital computing node that utilizes continuous solar power and radiative cooling to enable high-performance data processing in space. The node uses optical inter-satellite links and advanced relay networks to ensure continuous availability, consistent with ground-based application servers.
4
Sophia Space
Country: USA | Funding: $13.9M
Sophia Space is building solar-powered, space-cooled, AI-ready orbital computing and data centers. The company's technology is based on a sail-like design that is thinner and more flexible than bulky traditional satellites. Sophia has also developed modular server racks with integrated solar panels, which it calls TILES. This thin form factor allows processors to be positioned close to the passive heat sink, eliminating the need for active cooling. It is expected that 92% of the generated energy will be directed toward data processing. The company plans to first test a new approach to passively cooling space computers on Earth, then acquire a satellite platform from Apex Space and demonstrate its operational capability in orbit by late 2027 or early 2028.
5
SkyServe
Country: India | Funding: $3.2M
SkyServe is an edge computing startup, working with NASA’s Jet Propulsion Laboratory to test artificial intelligence models on a D-Orbit satellite.
6
OrbitsEdge
Country: US | Funding: $250K
OrbitsEdge provides the first commercial access to datacenter-grade computing and analytics in orbit.
7
LEOcloud
Country: USA
LEOcloud is focused on providing space-based edge computing, including data centers in orbit.
8
Thales Alenia Space
Country: France
Thales Alenia Space has designed, integrated, tested, operated and delivered innovative space systems.
9
Madari Space
Country: UAE
Madari builds space data centers. The company claims that placing data centers in space provides an additional level of security, as they are protected from terrestrial threats such as extreme weather conditions and terrorist attacks. Madari offers encrypted data transmission services, ensuring confidentiality and integrity. The company also ensures compliance with industry standards and regulatory requirements. Madari focuses on addressing Earth's environmental challenges associated with excessive energy consumption. Their solution utilizes solar energy and cooling from the space environment.
