Impulse Space raised $150M Series B in 2024 for its high-performance chemical propulsion spacecraft (Mira and Helios) that provide in-space transportation, enabling rapid satellite deployment and orbital transfer.
Impulse Space develops orbital transfer vehicles (OTVs) — spacecraft with high-performance chemical propulsion systems that can transport satellite payloads from launch vehicle deployment orbits to their operational orbits, or maneuver constellations for rapid response missions. The company's Mira vehicle targets LEO and MEO missions while the larger Helios vehicle aims for GEO and cislunar missions.
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.
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.
