EnduroSat

Manufactures standardized satellite platforms and missions

EnduroSat manufactures standardized, serial-production satellite platforms and provides space services for commercial, government and defense missions. Its products span small to mid-sized satellites, from 8U-16U CubeSats to ESPA-class 200-500 kg systems and up to five-ton Starlink V2 dispenser-compatible platforms. The company operates an end-to-end, fixed-cost service model that covers mission design, payload integration, launch coordination, and in-orbit operations, aiming to reduce cost, risk, and time to orbit. EnduroSat has 100+ satellites in orbit and 450+ customers, with production facilities in Europe, the US, and Japan. It has raised over $350 million in funding (including a $205 million round in September 2026 co-led by Riot Ventures and Atreides Management). Its goal is to be a trusted, scalable partner for customers executing commercial, government, and defense space missions by delivering predictable, turnkey missions from idea to orbit.
