Starcloud is a US deep-tech company building data centers in orbit. By placing GPU clusters in space, it taps near-continuous solar power and passive radiative cooling to run AI training and inference without the land, water, grid-permitting, and energy constraints that bottleneck data centers on Earth. In November 2025 its Starcloud-1 satellite became the first spacecraft to train a large language model in orbit using an Nvidia H100 GPU; its $170M Series A in March 2026 made it the fastest unicorn in Y Combinator history.
Loft Orbital is a San Francisco-based space infrastructure company that flies customer payloads on standardized satellites - selling space access the way AWS sells compute. Customers skip the spacecraft-building part and ship hardware, software, or on-demand data tasks to orbit on Loft's YAM satellites.
Muon Space is a Mountain View-based end-to-end space systems company that designs, builds, and operates mission-optimized satellite constellations for climate, defense, and Earth intelligence customers. Its Halo platform pairs the modular MuSat spacecraft bus with MuOS middleware and the MuSim digital twin, anchoring high-profile programs like Google's FireSat wildfire constellation and a $44.6M U.S. Space Force environmental monitoring agreement.
Pierre-Damien Vaujour is the co-founder and CEO of Loft Orbital, the San Francisco-based company that turned satellite deployment from a multi-year aerospace engineering odyssey into something closer to provisioning a cloud server. A French aerospace engineer by training — ISAE-SUPAERO class of 2008, master's from University of Michigan — he cut his teeth at ESA, NASA, the Google Lunar X PRIZE, and was among the first hires at Spire Global before co-founding Loft Orbital in 2017 with Alex Greenberg and Antoine de Chassy. Under his leadership, the company reached unicorn status in January 2025 with a $170M Series C, surpassed $500M in cumulative bookings, and is now building the default AI execution layer for orbital infrastructure.
Astro Digital designs, builds and operates small-satellite systems delivered as turn-key 'Mission-as-a-Service' offerings - covering spacecraft bus, payload integration, launch, ground network and mission operations - for earth observation, communications, science and in-orbit demonstration customers from LEO to GEO.
Ignacio Belieres Montero is the founder and CEO of Epic Aerospace, a Los Altos, California-based company building orbit transfer vehicles and space tugs that move satellites from one orbit to another. A Stanford aerospace engineering graduate and Y Combinator S19 alum, he started building rockets at 16 and founded Epic Aerospace in 2017. The company's CHIMERA LEO 1 launched aboard SpaceX Transporter 6 in January 2023, and CHIMERA GEO 1 launched on SpaceX's Intuitive Machines-2 mission in February 2025, reaching 53 million kilometers from Earth. Epic Aerospace reached $4.2M in annual revenue in 2024 with a 28-person team, pioneering non-toxic hypergolic propulsion technology for cost-effective in-space transportation.
