Relativity Space vs Apex Space
Side-by-side comparison of AI visibility scores, market position, and capabilities
Relativity Space is building the world's first fully 3D-printed rocket, using autonomous robotic manufacturing to reduce production time from years to 60 days. HQ: Long Beach, CA.
About
Relativity Space is an aerospace company pioneering a new approach to rocket manufacturing through large-scale 3D printing and autonomous robotics, with the goal of building a fully vertically integrated launch company that can design, manufacture, and launch rockets at a fraction of traditional cost and time. Founded in 2015 by Tim Ellis and Jordan Noone, former SpaceX and Blue Origin engineers, Relativity uses its proprietary Stargate metal 3D printing system — the world's largest metal 3D printer — to fabricate rocket structures from aluminum alloy, reducing part counts from 100,000+ (traditional rockets) to under 1,000.
Apex Space raised $400M across Series C and D rounds in 2025, achieving a $1B+ valuation, as the first manufacturer to offer productized 100–500kg satellite buses at high production rates for commercial and government LEO constellation customers.
About
Apex Space is a spacecraft manufacturer founded in 2022 that produces productized, configurable satellite bus platforms ranging from 100 to 500 kilograms, designed for rapid delivery and scalability to serve the growing demand for commercial and government space missions. Unlike traditional satellite manufacturers that build fully custom spacecraft for each customer, Apex offers standardized bus platforms that dramatically reduce lead times and per-unit costs, enabling customers to deploy constellations at production scale.
