Oligo Space
Oligo Space is a Hawthorne, California startup building an AI-first stack for designing and manufacturing payload-centered spacecraft. Its software engine, Zenith, turns raw mission requirements into flight-ready ESPA-class spacecraft using generative design, constraint solving and physics-based optimization - compressing work that once took teams of specialists months into a process that runs in minutes and manufactures in under eight months. Founded in 2024 by MIT AeroAstro graduate and former NASA JPL engineer Jacob Rodriguez, the company plans to fly its first spacecraft, Chimera-1, aboard SpaceX's Transporter-15 mission in 2026.
Epic Aerospace
Epic Aerospace builds Orbit Transfer Vehicles - small chemical space tugs that pick up satellites from crowded rideshare drop-offs and ferry them to their actual working orbits, from LEO to GEO and beyond. Founded in 2018 by Ignacio Belieres Montero, the company runs its engineering and manufacturing out of Argentina with a U.S. headquarters, and put its first GEO-class vehicle, CHIMERA GEO 1, into space aboard SpaceX in early 2025.
Starcloud
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
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
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.
Astro Digital
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.
