What Aethero does
Aethero is a San Francisco-based space computing startup founded in 2023 that develops radiation-hardened GPU compute modules for orbital deployment, targeting two customer bases: enterprise AI infrastructure customers constrained by terrestrial grid capacity, and space mission operators requiring advanced onboard compute. The company's core product is the NxA-ECM compute module, built on Nvidia's Blackwell-based Jetson Thor architecture, designed to be integrated with third-party satellite buses. Aethero has flown two CubeSat demonstrators — Phobos (~157 TFLOPS) and Deimos (~100 TFLOPS) — and is preparing the Titan mission for an October 2026 launch on SpaceX's Transporter-18 rideshare via a co-development partnership with EnduroSat, targeting a clustered 'space cloud provider' architecture delivering more than 16,000 TFLOPS in orbit.
The business model is forward-looking subscription-based orbital compute infrastructure, delivered to enterprise customers through direct B2B partnerships and platform integrations rather than traditional sales channels. To date, Aethero's only disclosed commercial activity is its June 2025 $8.4 million seed round led by Kindred Ventures and Alumni Ventures (with Giant Step Capital, Neo, SHOR, and O'Shaughnessy Ventures participating), used to fund hardware/software development and additional satellite demonstration missions. The company is privately held, operates with an 11–50 person team led by CEO Edward Ge and CTO/Co-founder Amit Pinnamaneni, and has filed with the FCC in support of its orbital operations. No revenue, ARR, or customer logos have been disclosed; current activity is centered on technology validation rather than commercial compute sales.

Aethero product offering
Product offeringCore offering
Aethero designs and manufactures radiation-hardened compute modules (NxA-ECM) based on Nvidia Blackwell architecture (Jetson Thor processors) for deployment on satellites. The modules are clustered into a space cloud provider architecture that links multiple compute spacecraft into a coordinated orbital data center, enabling high-performance in-orbit computing for AI/ML workloads and advanced space missions. The company has progressed from CubeSat demonstrations (Deimos, Phobos) to a planned Titan mission targeting over 16,000 TFLOPS of in-orbit performance.
Product overview
Aethero is a space-focused startup based in San Francisco developing space-grade hardware and software for in-orbit computing. The company operates a portfolio of compute modules and satellite missions: the NxA-ECM compute module serves as the core technology, which has been demonstrated through earlier Phobos (~157 TFLOPS) and Deimos (~100 TFLOPS) CubeSat missions. The next-generation Titan mission, integrating the NxA-ECM with EnduroSat's FRAME-15 platform, aims to achieve over 16,000 TFLOPS and function as a clustered space cloud provider system enabling distributed orbital data centers at scale.
