Cowboy Space launches satellite to demonstrate first laser power beaming from orbit to Earth

Cowboy Space Corporation, founded by Robinhood co-founder Baiju Bhatt, has launched Reason-1, its first satellite, to demonstrate laser power beaming from orbit to Earth. The satellite will collect solar energy in space and transmit it to a ground receiver using a kilowatt-class laser. The mission will test optical and thermal technologies for Cowboy's planned orbital data centres. The company designed and built Reason-1's laser systems, optical telescope, and beam-steering architecture in-house. Cowboy is developing a rocket whose upper stage will function as a 1-megawatt data centre in orbit. The company is also collaborating with NVIDIA to deploy computing modules in low Earth orbit. A follow-up mission, Reason-2, is scheduled for launch in 2027. The San Carlos-based company is backed by Index Ventures, Breakthrough Energy Ventures, and other investors.

Aetherflux in talks for $250-350M Series B at $2B valuation led by Index Ventures.

Aetherflux in talks for $250-350M Series B at $2B valuation led by Index Ventures. March 28, 2026 at 11:40 AM - by MLQ Agent Key points. * Aetherflux is in talks for a Series B round of $250 million to $350 million at a $2 billion valuation, led by Index Ventures14. * The company, co-founded by Robinhood's Baiju Bhatt, has raised about $80 million since 2024, following a $50 million Series A in April 2025 that brought total funding to $60 million124. * Aetherflux is pivoting from laser-based Earth power transmission to space-based data centers to address AI energy demands, with its first satellite targeted for 20272. * Previous investors include Index Ventures, Breakthrough Energy Ventures, Andreessen Horowitz, and NEA; the company has U.S. Department of Defense support123. Aetherflux, the space solar power startup co-founded by Robinhood co-founder Baiju Bhatt, is negotiating a Series B funding round of $250 million to $350 million at a $2 billion valuation, led by Index Ventures. The company, which has raised about $80 million since its 2024 founding, is shifting focus to orbital data centers for AI computing needs. Company background and prior funding. Aetherflux, headquartered in San Carlos, California, was founded in 2024 by Baiju Bhatt, co-founder of Robinhood. The startup emerged from stealth in late 2024 and raised $50 million in a Series A round in April 2025, led by Index Ventures and Interlagos, with participation from Bill Gates's Breakthrough Energy Ventures, Andreessen Horowitz, NEA, and others. This brought total funding to $60 million, including Bhatt's $10 million personal investment 124. The funds supported hiring engineers and developing technology for initial missions. Technology pivot and development plans. Initially focused on space-based solar power using infrared lasers to transmit energy to Earth ground stations, Aetherflux aimed for a low Earth orbit demonstration in 2026. The company received funding from the U.S. Department of Defense's Operational Energy Capability Improvement Fund for military applications 123. It is now pivoting to 'Galactic Brain,' a constellation of satellites serving as orbital data centers powered by space solar energy to meet AI computing demands. The first commercial data center node is slated for launch in 2027 2. Investor interest and strategic expansion. The potential Series B would mark a significant jump from prior rounds, reflecting investor appetite for orbital infrastructure amid AI energy challenges. Index Ventures, an existing backer, is leading the talks. Aetherflux has expanded with a new hub in Seattle for satellite development and employs talent from SpaceX, NASA, Robinhood, and the U.S. Navy 2. Valuation jump drivers. The proposed $2 billion valuation for Aetherflux's Series B represents a more than 33-fold increase from its post-money valuation after the $50 million Series A, which totaled around $60 million raised 14. This surge aligns with heightened venture capital flows into space infrastructure, driven by AI's escalating power requirements that terrestrial grids struggle to meet. Aetherflux's pivot from general space solar to AI-specific orbital data centers positions it to tap into a market where hyperscalers like those backed by Andreessen Horowitz face energy bottlenecks 2. Existing DoD funding validates the laser transmission tech for remote and military use, potentially de-risking commercial scalability 13 . Index Ventures' repeat leadership signals confidence in execution, given their early Series A involvement and public endorsement of the energy-to-Earth vision 5. However, the shift from 2026 power demos to 2027 data centers introduces execution risks, as satellite constellations demand reliable power beaming over vast distances. Competition from entities like Caltech, Virtus Solis, and state-backed projects in the UK and China adds pressure, though Aetherflux's AI focus and Bhatt's track record differentiate it 3. Satellite launch timeline. Aetherflux's first orbital data center satellite in 2027 will serve as a critical proof-of-concept for the Galactic Brain constellation, potentially unlocking follow-on funding if it demonstrates reliable solar-powered AI computing 2. Success could accelerate deployments, with the Seattle hub enabling faster iteration amid the regional space talent pool. Regulatory approvals for orbital operations and spectrum allocation for laser transmission remain key hurdles, especially with DoD ties possibly expediting military validations 13 . Broader market adoption hinges on cost reductions in launches and power efficiency, areas where SpaceX alumni on the team may provide edges. If the Series B closes at the high end, Aetherflux could expand its 10-person team significantly, targeting hyperscale AI providers strained by Earth-bound energy limits 24. Investor momentum from this round may spur parallel investments in space-AI infrastructure, reshaping orbital economics by 2030. Further sources.
