Sophia Space, a startup focused on space-based computing and orbital data centers, has raised $10 million in seed funding to demonstrate a new generation of passively cooled space computers. The funding will support development of its innovative TILE modular computing system, designed to process massive volumes of satellite data directly in orbit.
With backing from investors such as Alpha Funds and partnerships with Nvidia, the company plans to test the technology on a satellite by 2027–2028, potentially transforming how AI and data processing work in space.
As space companies race to deploy high-performance chips and AI processors in orbit, one critical engineering challenge continues to stand in the way: how to keep those powerful processors cool in space. While outer space is extremely cold, it lacks something essential for traditional cooling systems—airflow. Without air, heat cannot dissipate easily, making thermal management one of the biggest barriers to building space-based data centers.
This challenge was highlighted by Nvidia CEO Jensen Huang, who recently explained that despite the cold environment of space, heat can only dissipate through conduction, making efficient cooling systems crucial for orbital computing.
To tackle this problem, Sophia Space has secured $10 million in seed funding from investors including Alpha Funds, KDDI Green Partners Fund, and Unlock Venture Partners. The startup plans to demonstrate a new passive cooling approach for space computers, first testing it on Earth and later deploying it on a satellite built by Apex Space. The in-orbit demonstration is expected by late 2027 or early 2028.
Unlike traditional designs being explored by companies such as SpaceX or Google—which rely on large radiators to cool processors—Sophia Space is pursuing a radically different architecture. The company’s concept originates from a Caltech research initiative focused on developing orbital solar power systems capable of transmitting electricity to Earth.
During that research, engineers created a thin, flexible sail-like structure that differed significantly from conventional box-shaped satellites. While using these structures for space-based power generation proved difficult due to technical and regulatory hurdles, Sophia Space’s team realized the design could be ideal for powering and cooling computers in orbit.
Building on this concept, Sophia Space—an Nvidia partner—developed modular computing units called TILES. Each TILE integrates solar panels and processors in a compact 1-meter-by-1-meter module just a few centimeters thick. This ultra-thin design allows processors to sit directly against a passive heat spreader, eliminating the need for complex cooling systems.
As a result, the company expects up to 92% of generated power to be used for computing, a major efficiency improvement over traditional satellite designs. However, achieving this efficiency requires a highly advanced software management system capable of balancing workloads across processors in real time.
With its innovative architecture and fresh funding, Sophia Space aims to demonstrate that efficient, passively cooled computers can operate directly in orbit, potentially paving the way for next-generation space data centers and AI processing in space.
Sophia Space Raises $10M Seed to Demo Novel Space Computers
Why Is Computing in Space So Challenging?
Imagine satellites collecting terabytes or even petabytes of data every few minutes, but discarding much of it because they lack the computing power to process it in orbit. That’s a major challenge facing the modern space industry.
Even though space is cold, cooling powerful processors in orbit is surprisingly difficult because there’s no air to carry heat away. Traditional systems rely on large radiators or bulky cooling solutions that add weight and complexity.
To tackle this issue, startup Sophia Space has raised $10 million in seed funding to build and demonstrate a new type of space computer designed specifically for orbital environments.

What Makes Sophia Space’s Technology Unique?
1. The TILE Modular Computing System
At the core of Sophia Space’s innovation is a technology called TILE.
Key specifications:
- Each TILE measures about 1 meter by 1 meter
- Only a few centimeters thick
- Integrates solar power and computing hardware

2. Passive Cooling Instead of Fans
Unlike conventional computers, Sophia’s system uses passive cooling through thermal conduction.
Benefits include:
- No moving parts
- Lower energy consumption
- Reduced system complexity
This approach solves one of the biggest engineering challenges in space: heat dissipation without airflow.
3. Higher Processing Efficiency
According to the company, up to 92% of generated power can go directly toward computing tasks, a major improvement compared to traditional satellite systems.
That efficiency could enable real-time data analysis in orbit.
Why Space-Based Computing Matters
Space computing is becoming critical as satellites generate massive datasets from sensors and cameras.
Applications include:
- Earth observation satellites
- Defense and missile tracking systems
- Climate monitoring
- Global communications networks
- AI edge processing in orbit
Processing data directly in space reduces:
- Latency
- Bandwidth requirements
- Data transmission costs
This means faster insights and real-time decision-making.
Sophia Space’s Long-Term Vision
The company isn’t just building satellite computers—it aims to create large orbital data centers.
Future plans include:
- A 50m × 50m space computing structure
