COMPANY PROFILE / SPACE INDUSTRY

Starcloud
A young company that wants data centers in space: one 60 kg demonstration satellite so far, and a concept of tens of thousands of satellites at gigawatt scale

AI computing needs huge amounts of electricity and cooling. Starcloud wants to make a business of putting the computers not on the ground but in an orbit where the Sun shines almost all the time. In November 2025 it launched Starcloud-1, a satellite of about 60 kg carrying a data-center-class GPU (the NVIDIA H100). Its white paper and its application to the FCC (the U.S. Federal Communications Commission) describe something on a different scale: up to 88,000 satellites and a 5-gigawatt facility. This profile separates what has already been demonstrated from what is still a concept or an application.

Sources: the company's website and white paper, U.S. SEC (Form D) and FCC public documents, and official announcements by NVIDIA and Crusoe. The space business changes fast, so dates of checking are given. Last updated 17 October 2026.

1. Starcloud in 30 seconds, and where it stands in the space industry

LEGAL NAMEStarcloud, Inc.Formerly Lumen Orbit, Inc. (a footnote in the white paper says it was renamed in 2025)
HEADQUARTERSRedmond, Washington, USA2517 152nd Avenue NE (official site and FCC application)
INCORPORATED2023, DelawareAs stated in its Form D (checked 17 October 2026)
LISTINGPrivateNot traded on any stock market. Revenue is not disclosed
CATEGORY IN THIS FIELDSatellites and in-orbit services
(space data centers)
It builds computers to sit in orbit, not rockets
WHAT IT HAS DEMONSTRATEDStarcloud-1 (launched 2 November 2025)About 60 kg, with one NVIDIA H100 (per NVIDIA and the company)
NEXT SATELLITEStarcloud-2The first commercial satellite. The website says operational by 2027. The date is not confirmed
CONCEPT AND FILINGUp to 88,000 satellites
5 GW class
An FCC application (under review) and a white paper. Realisation is in the future
The one thing to grasp first: a large gap between demonstration and concept

Talk of data centers in space can sound as if huge facilities already circle the Earth. What can be confirmed in orbit today is one test satellite of about 60 kg Sourced. The company's page says that in December 2025 this satellite ran Gemma, Google's open model, and trained nanoGPT, a small language model (the company's own account; this article found no independent verification record).

By contrast, up to 88,000 satellites (the FCC application) and a 5-gigawatt facility with solar arrays about 4 km on a side (the white paper and NVIDIA's blog) are an application or a concept Not yet confirmed. The application had only reached the stage of being accepted for filing by the FCC (13 March 2026), and this article found no record that a licence has been granted. The article keeps the two apart.

2. The logo and how the name is written

A note on names: the company is Starcloud, Inc. Its former name was Lumen Orbit, Inc., and both its January 2025 SEC Form D and its September 2024 white paper were issued under that name. The satellite also remains registered under the alias "LUMEN-1" (SatNOGS DB). A search of the SEC's database also turns up several Form D filings by separate investment vehicles (SPVs, or special-purpose vehicles) with "Starcloud" in their names. This article has not established how those relate to the company itself, so for the company's funding it uses only the filing made in the name of Lumen Orbit, Inc.

3. Where the company sits in the space industry

Four types of company in the space industry The same "space company" label hides different roles in orbit, and so different strengths and challenges Launch Exploration, crewed & lunar Satellites, in-orbit services & manufacturing Parts & systems Carry payloads to space To the Moon and stations Operate and build in orbit Support the spacecraft SpaceX / Blue Origin Rocket Lab / Firefly Axiom Space Intuitive Machines ispace / Astrobotic Astroscale / Varda Synspective / Starcloud Northrop Grumman / BAE Systems / Microchip / Redwire Launch capacity and reuse Reach to the Moon and ISS New uses and markets Track record, reliability Failures, schedule slips Funding and schedule risk Demos, unproven revenue Slow to qualify and ship Starcloud is a "satellite" company that builds computers to run in space, not comms or imaging craft Proven so far: one 60 kg satellite. The 88,000-satellite, 5 GW vision is an FCC filing and a white paper
Fig. 1 The four types of company in the space industry, and where Starcloud sits. The classification is our own, and the companies shown are examples drawn from this series Our calculation. Starcloud's main type is satellites, in-orbit services and manufacturing. It relies on others for launch (Starcloud-1 flew on a SpaceX rocket).
A "satellite", but with a different job from a communications or imaging satellite

A communications satellite relays radio signals, and an imaging satellite photographs the ground. The satellite Starcloud wants to build is one in which the on-board GPUs (chips for AI computing) do the computing themselves. The plan is to link it by laser to other companies' communications networks (Starlink and others) to carry results and data (FCC application; the application says this is "subject to commercial arrangements", that is, depends on deals to be made).

Our series explainers on orbital computing, low-Earth-orbit constellations and optical inter-satellite links cover the mechanisms in detail.

4. Scale (private, with little disclosed)

Starcloud is a private company and publishes no audited accounts or annual securities reports. The table shows only what could be confirmed from the company's own materials and its SEC filing (Form D) Sourced.

ItemWhat could be confirmedCategory
IncorporationIncorporated in 2023 as a Delaware corporation (Form D). Located in Redmond, WashingtonSourced
Officers (as listed in Form D)Philip Johnston, Ezra Feilden and Paul Adrian Oltean (each an Executive Officer and Director), and Morgan Beller (Director)Sourced
Founders (official site)Philip Johnston (CEO), Ezra Feilden (CTO) and Adi Oltean (Chief Engineer). Their backgrounds are on the websiteSourced
HeadcountNot disclosed (the Team page lists names and backgrounds, not the total)Not disclosed

Funding (statutory filing)Form D (filed 13 January 2025): sales began on 5 December 2024; total sold US$14,137,498; 65 investors; no sales commissionsSourced
A caution

A Form D is a notice that a private company files when it raises money in certain private placements. It is not a financial statement. The amount above is the total for that one offering, not everything the company has raised.

The company is reported to have announced further funding in 2026, but this article could not open the announcement text (on a wire service), so it gives no amount, investors or company valuation for it Not yet confirmed. Figures from press reports and databases are not used.

5. Resources committed to space

The table shows, for four items (people, money, outside investments and acquisitions, and contracts with public bodies), whether primary sources confirm them. "Not in the record" is itself a finding.

No record of a licence could be confirmedApplication (under review)References 6 and 7
A materials engineer's view: the materials that matter for cooling and powering a data center in space

In space there is no air, so radiation (emitting infrared) is the only way to shed heat. The white paper calculates that a black plate at 20 °C with an emissivity of 0.92 radiates about 770 W from its two faces, and after subtracting absorbed sunlight and Earth's heat can shed about 633 W per square metre Sourced (the company's estimate; the emissivity and absorptivity are values it takes from NASA documents). The design therefore turns on coatings and surface materials with high emissivity that absorb little sunlight, and on radiators that are light and can unfold over a very large area. Our explainers on thermal-control materials and radiative cooling, and on spacecraft thermal control, are relevant.

On the electrical side, the white paper envisages silicon solar cells thinner than 25 µm (more than 1,000 W per kilogram) that are rolled up for launch and unrolled in orbit. It says radiation damage heals by annealing at moderate temperatures, even without cover glass (the company's claim). The same paper also says that storage and power-delivery parts are sensitive to radiation and need shielding.

All four items are plans of the company or its partners, not things that have been achieved Not yet confirmed.

What could not be confirmed

None of the following appears in the primary sources checked for this article Not yet confirmed.

A fixed launch date and launch vehicle for Starcloud-2 / the specifications of Starcloud-3 and -4 / the power and GPU count of a single satellite / contracts with public bodies / investment in manufacturing sites / independent verification of Starcloud-1's results. Figures that appear only in press coverage (satellite power, amounts raised, valuations) are not used.

8. What the company is aiming for in space

This section includes things the company has not said directly. They are inferences within what the primary sources support, given with their grounds.

What can be read from the recordPrimary-source basisCategory
The end goal is a gigawatt-scale AI computing base that avoids the limits of ground power, cooling and permittingThe white paper's summary (5 GW, solar arrays about 4 km on a side) and the FCC application (up to 88,000 satellites, and its references to limits of the terrestrial grid)Sourced (company's goal)
The near-term revenue is more likely to come from processing data that is generated in orbit than from AI training for the groundThe Starcloud-2 page lists in-space users (such as Earth-observation data) first and ground users second. NVIDIA's blog also names Earth-observation analysis as the first useInference
88,000 is probably a ceiling reserved for the review, not a target to buildThe application says "up to 88,000" and describes testing in low orbits first. The attached Schedule S (draft) has only two orbital planes with one satellite each, and its relation to 88,000 is not explainedInference
Scaling up depends on the launch price of large reusable rocketsThe white paper's estimates assume future prices such as US$5 million for 100 tonnes. The FCC application also refers to fully reusable Starship-class rocketsInference
It will keep its computing chips centred on NVIDIAThe H100 on board, the Blackwell consideration (NVIDIA's blog) and the mention in NVIDIA's releaseInference
One inference in more detail: is 88,000 a number of satellites to be built?

The FCC application describes a constellation of "up to 88,000" satellites placed in sun-synchronous orbits at 600 to 850 km, in thin shells no more than 50 km deep Sourced. It also says the first satellites will be tested at low altitude, so that any that fail early fall into the atmosphere and burn up, before being raised to the operating orbit.

Yet the Schedule S (the technical input form) attached to the same application lists only two orbital planes (at 600 km and 850 km) with one satellite each Sourced. The record does not say what that form represents, and this article gives it no meaning. Still, from the word "up to" and the cautious start, this article reads 88,000 as a ceiling to be secured in the review, not a number to be built from the outset Not yet confirmed. The real number has to be checked against whatever plan the company publishes later.

9. Map of space-industry partnerships

Partnerships centred on Starcloud Only ties stated in official materials, FCC documents or the partner's own release. No press-only ties Starcloud Orbital compute Crusoe Cloud from a satellite (plan) Google Gemma run (company's account) NVIDIA GPU (H100) choice, Inception SpaceX Launch of Starcloud-1 (2025) FCC: up to 88,000 satellites applied for (no licence confirmed) Plans and use with a partner Supplier of parts or launch Application or unconfirmed (dotted)
Fig. 2 Partnerships centred on Starcloud. Sources: the company's website, FCC documents, and announcements by NVIDIA and Crusoe. The figure includes only relationships stated in primary sources. The application names Starlink, Amazon LEO, Terrawave, Kepler Communications and others as possible future optical-link partners, but says this is "subject to commercial arrangements" and does not state that any is contracted, so they are not drawn.

10. Technology, products and services

At present only Starcloud-1 is actually in orbit. Everything else is a plan or a concept. According to the Starcloud-2 page on the website, the company expects two kinds of user.

ItemThe company's descriptionCategory
In-space users (expected)Process in orbit the large volumes of raw data that spacecraft and space stations produce every day, cutting the amount that must be sent down. Examples: analysing raw data from Earth-observation satellitesPlan
Ground users (expected)Secure data storage independent of Earth, and a "sovereign cloud" (computing that a country or company controls itself)Plan
Design concept (white paper)Computing "containers" joined to solar arrays and radiators, and added to over time. A dawn-dusk orbit (the Sun shines almost continuously). Heat shed by radiation, communications by laserConcept (company document)
The company's estimate (white paper)"About 22 times cheaper power" (US$0.002 per kWh). It assumes a future rocket carrying 100 tonnes for US$5 million per launch and solar cells at US$0.03 per watt, among other things, so these are not current pricesNot yet confirmed
A materials engineer's view: assumptions to check when reading the estimates, and a simple cross-check

The white paper sizes the solar array for a 5 GW data center at about 4 km by 4 km (cell efficiency 22%, fill factor 90%, silicon cells). Using the solar intensity the paper itself uses (1,366 W per square metre), a simple calculation gives about 4.3 GW from 16 square kilometres Our calculation. That is within the range of "about", but slightly short of 5 GW, and real arrays would also lose output to degradation and wiring losses. It is safest to read the concept's numbers as rounded and dependent on assumptions.

On radiation, the white paper cites research suggesting logic circuits are fairly tolerant, and argues that the share of shielding falls as the compute grows, because shielding mass scales with surface area while compute scales with volume (the company's view). Whether a result from one small satellite carries over to a container of about 100 tonnes can be checked using the approach in our explainers on radiation and electronic parts and on space-grade semiconductors and COTS (commercial off-the-shelf parts).

11. The risks this company carries

RiskWhat it isCategory
The gap between demonstration and conceptWhat is confirmed in orbit is one satellite of about 60 kg. The concept is up to 88,000 satellites and 5 GW. Engineering problems in between (unfolding huge arrays, shedding heat, maintenance) cannot be settled by a one-satellite demonstrationSourced
Dependence on large rockets and their pricesThe white paper's estimates assume future prices for reusable launchSourced (stated assumption)
Review and regulationThe FCC application has only been accepted for filing. It also asks for waivers of five rules. Secure World Foundation has filed comments calling for careful review and phased authorisationSourced
Effects on the orbital environmentA huge increase in satellite numbers raises collision risk, debris and effects on astronomy. Both the company's explanation (testing at low altitude, automated collision avoidance, designs that burn up on re-entry) and third-party concerns are public. This article does not assess the actual effectSourced
Range of datesOn Starcloud-2, the website (by 2027) and Crusoe's announcement (late 2026) are not the same dateSourced
Verification rests on the company's accountThe December 2025 Gemma run and nanoGPT training rest mainly on the company's own page, and this article found no independent verification recordSourced
Finances are opaqueRevenue, headcount and R&D spending are not disclosed. The 2026 funding could not be readSourced / not disclosed
Dependence on chip supply and generationsThe on-board computers centre on NVIDIA parts, so product generations and supply at that company would affect itInference

12. Glossary

Orbital data center
Computers (GPUs and the like) carried on satellites or structures orbiting the Earth instead of in a building on the ground.
GPU
A chip that grew out of graphics processing and is good at parallel computation. The workhorse of AI training and inference.
H100
