Starcloud raised a $250M Series A extension (bringing the round to $420M and valuing the company at $2.3B) to build larger manufacturing capacity and its Starcloud-3 orbital AI data center, while securing launch capacity as SpaceX phases out Falcon 9 and Starship faces delays. Investors include Manhattan West Ventures, Nvidia (which invested $25M), Cisco and others; Starcloud operates Nvidia H100 GPUs in orbit and plans to fly Nvidia's Vera Rubin Space-1 chip by late 2028.

Starcloud raises $250M extension to March Series A, valuing company at $2.3B to build Starcloud-3 and expand manufacturing

Space startup Starcloud extended its March Series A with a $250 million addition, bringing its valuation to $2.3 billion and funding expansion of manufacturing and its Starcloud-3 orbital data center planned to fly on SpaceX’s Starship. The round, led by Manhattan West Ventures with participation from Nvidia and Cisco, will also help secure launch capacity amid tightening rocket availability.

Starcloud raises $250M Series A extension led by Manhattan West, valuing company at $2.3B

Orbital data center startup Starcloud raised an additional $250 million in a Series A expansion led by Manhattan West, bringing total Series A proceeds to $450 million and valuing the company at $2.3 billion. The funding will expand manufacturing, engineering with Nvidia, and launch access as Starcloud pursues an 88,000-satellite constellation and has already placed an Nvidia H100 GPU in orbit running Google’s Gemini.

Starcloud Raises $250M Extension, Valued at $2.3B to Build Starcloud-3 and Orbital AI Data Centers

Starcloud raised an additional $250 million in a Series A extension, bringing its valuation to $2.3 billion after a prior $170 million raise, to build larger satellites and an orbital AI data center. The company plans to scale production of its Starcloud-3 spacecraft, secure launch capacity (including SpaceX Starship flights), and has applied to the FCC to operate 88,000 spacecraft.

Starcloud Raises $250M Series A Extension, Valued at $2.3B to Build Orbital AI Data Centers

Redmond-based Starcloud raised a $250 million Series A extension, valuing the company at $2.3 billion and bringing total funding to $450 million to build orbital data centers for AI. The round was led by Manhattan West and includes new strategic investors such as Nvidia and Cisco Investments, continuing a collaboration that began when Starcloud launched an NVIDIA H100 GPU to orbit in November 2025.

Starcloud raises $250M at $2.3B valuation to scale space-based AI data centers, led by Manhattan West

Starcloud raised $250 million in a Series A extension at a $2.3 billion post-money valuation to expand its space-based data centers, fund manufacturing, engineering with NVIDIA, and secure future launches. The company — which launched an NVIDIA H100 on Starcloud-1 in November 2025 and has run AI models in orbit — plans a constellation targeting 88,000 satellites and 20 GW of orbital compute.

Starcloud adds $250M to Series A, now valued at $2.3B, to build orbital data centers and secure launches

Starcloud raised a $250 million extension to its March $170 million Series A, valuing the company at $2.3 billion, to expand manufacturing and develop its Starcloud-3 orbital data center amid tightening launch availability. The startup plans rideshare launches of two 8 kW Starcloud-2 satellites in 2027 and is securing capital and launch contracts as major rockets like Falcon 9 phase out.

Seattle’s ‘Third Act’: VCs Say Local Superstars Are Deep-Tech Startups Building Rockets, Geothermal Plants and Autonomous Vehicles

Two Seattle venture capitalists argue that the city’s next wave of superstar startups are already here but focus on deep tech—intelligent machines and physical products like rockets, geothermal plants and autonomous off-road vehicles—rather than pure software. They frame this shift as Seattle’s "Third Act," building on maritime/aerospace roots (Act I) and the software/cloud boom (Act II) to combine hardware and software using local infrastructure and talent.

Starcloud Raises $170M, Pioneers AI GPU Satellite in Race for Space-Based Data Centers

Starcloud, a startup valued at $1.1 billion, has launched a GPU-powered satellite into orbit and raised $170 million in Series A funding, aiming to build an 88,000-satellite constellation for AI data centers in space. The company leads a competitive race against giants like Google, SpaceX, and Blue Origin to establish orbital AI infrastructure before launch costs decrease.

Starcloud raises $170M Series A at $1.1B valuation to fund two satellites for orbital data centres

Starcloud raised $170 million in a Series A led by Benchmark and EQT Ventures at a $1.1 billion valuation to fund its next two satellites and advance orbital data-centre development, bringing total funding to $200 million. The Redmond startup already operates an Nvidia H100 GPU in orbit, trained the first AI model in space, and is building Starship-class spacecraft to make orbital data centres cost-competitive with terrestrial facilities.

Aetherflux, Founded by Robinhood's Baiju Bhatt, Expands to Seattle for Solar-Powered Orbital Data Center Satellite Development

Aetherflux, a space startup founded in 2024 by Robinhood co-founder Baiju Bhatt, is expanding to Seattle to develop solar-powered orbital data center satellites aimed at supporting AI energy needs, with a commercial launch planned for 2027. The company joins a growing aerospace community in Seattle, focusing on leveraging space-based infrastructure to overcome limitations of ground-based AI computing resources.

Bellevue Startup Lumen Orbit Raises $2.4M to Launch 300 Satellites for AI Data Processing in Space
