Cowboy Space Corporation

Cowboy Space Corporation, previously known as Aetherflux Inc., is an American renewable-energy and space-technology company based in San Carlos, California. The company was founded by Baiju Bhatt, the co-founder and former co-chief executive officer of Robinhood, and is focused on commercializing space-based solar power. Its central concept is to collect solar energy in orbit and deliver usable electricity to Earth, potentially providing power in locations where conventional terrestrial generation or grid connections are difficult to establish. The company’s proposed architecture uses solar panels mounted on satellites in low Earth orbit. Rather than transmitting energy through the microwave systems commonly associated with earlier space-solar concepts, Cowboy Space Corporation plans to use infrared lasers to send power toward receivers on the ground. This design is intended to support compact receiving infrastructure and flexible deployment. The company has described initial receivers as larger than 10 meters in diameter, while indicating that future engineering could reduce their size to roughly five to 10 meters or potentially smaller. The first target applications are specialized rather than mass-market electricity supply. The company has identified possible uses in United States military operations, remote scientific or research stations, and isolated mining sites. These environments can face high costs, logistical limitations, fuel-supply risks, or a lack of reliable grid access. Space-based generation could, if technically and economically validated, provide an additional source of power without requiring extensive terrestrial transmission construction. Bhatt’s interest in space technology was influenced by his father’s work as a scientist at NASA’s Langley Research Center. After leaving his leadership role at Robinhood in March 2024, Bhatt began working on the venture that later became public as Aetherflux. In October 2024, the company announced its operations and reported a team of approximately 10 people. It acquired a satellite bus from Apex, a satellite company in which Bhatt is an investor, and began developing the solar-power payload. The company stated that it intended to conduct an initial mission and space demonstration in early 2026. The business has also pursued government and commercial partnerships. It joined the Commercial Spaceflight Federation in October 2024, and the United States Department of Defense’s Operational Energy Capability Improvement Fund approved its space-solar program for support toward a proof of concept for transmitting power from low Earth orbit to Earth. In 2025, reporting described a $50 million Series A round and total funding of $60 million, with participation from venture firms, technology investors, and individual backers. These figures relate to the company’s private financing and do not represent public-market capitalization or revenue. In December 2025, the company announced the Galactic Brain project, an effort to develop an orbital data center powered by its space-based solar infrastructure, with a stated commercial-operation objective in the first quarter of 2027. This initiative broadened the company’s proposed scope from supplying power to terrestrial customers toward supporting energy-intensive computing in orbit. The company remains an early-stage venture whose long-term commercial prospects depend on launch economics, satellite durability, laser power transmission, receiver deployment, regulatory approval, orbital safety, and the ability to demonstrate reliable energy delivery at a competitive cost.

The technological premise behind Cowboy Space Corporation belongs to the long history of space-based solar-power proposals. The general idea is to place solar collectors above the atmosphere, where sunlight is available without the interruption caused by night, weather, or atmospheric absorption, and then transmit the collected energy to Earth. The concept has appeared in science fiction and engineering studies for decades. One early cultural precedent cited in connection with the company is Isaac Asimov’s 1941 short story “Reason.” The company’s former name, Aetherflux, was associated with older ideas about aether theories. The company emerged from the transition of Baiju Bhatt, a co-founder and former co-chief executive officer of Robinhood, from financial technology into space and energy. Bhatt left his Robinhood leadership role in March 2024 to focus on a new venture. His interest in space was partly shaped by his father’s work as a scientist at NASA’s Langley Research Center. The venture was publicly introduced in October 2024 under the name Aetherflux Inc., before later being identified as Cowboy Space Corporation. At launch, the company described a technical approach that differed from many previous government and university studies. Instead of relying on large geostationary platforms and microwave transmission, it proposed a constellation of comparatively compact satellites in low Earth orbit. Solar panels on the spacecraft would collect energy, while infrared lasers would direct power to receivers on Earth. The company has described receivers initially larger than 10 meters in diameter, with the possibility of reducing their dimensions through further development. This architecture is aimed at applications where a dedicated and flexible power source could be more valuable than immediate deployment for general utility-scale electricity. The company initially identified United States military activities, remote research facilities, and remote mining operations as potential users. These environments may have limited access to electrical grids and may depend on fuel transported over long distances. A space-based power system would need to demonstrate reliable pointing, atmospheric transmission, receiver safety, orbital persistence, and favorable economics before such applications could become practical. During its initial operating period, the company reported a team of approximately 10 employees. It purchased a satellite bus from Apex, a satellite company in which Bhatt is an investor, and began designing the payload intended for its first mission. The company stated an objective of conducting an early mission and space demonstration in 2026. It also joined the Commercial Spaceflight Federation in October 2024, aligning itself with a broader commercial-space industry group. Later that month, Daniel M. Gallagher, Robinhood Markets’ chief legal officer, became an advisor. The company’s development received additional private and government backing. In April 2025, reporting described a $50 million Series A round co-led by Index Ventures and Interlagos, with additional investment from Breakthrough Energy Ventures, Andreessen Horowitz, New Enterprise Associates, Robinhood co-founder Vlad Tenev, Daniel Gallagher, artist Jared Leto, and watchmaker François-Paul Journe. The reported financing brought total capital raised to $60 million. Separately, the United States Department of Defense’s Operational Energy Capability Improvement Fund approved the company’s space-solar program for funding toward a proof of concept demonstrating transmission of power from low Earth orbit to Earth. In December 2025, the company announced Galactic Brain, an orbital data-center initiative. The project proposed using the company’s space-based solar infrastructure to power artificial-intelligence computing in orbit, with an objective of commercial operation during the first quarter of 2027. This represented an expansion from supplying power to remote terrestrial users toward building energy infrastructure for orbital computing. As an early-stage company, Cowboy Space Corporation’s future depends on proving its hardware and transmission system, securing regulatory and launch approvals, managing orbital risks, and establishing a commercially viable customer and revenue model.
