EnduroSat

EnduroSat is a Bulgarian space company founded in 2015 in Sofia that designs, manufactures and operates software-defined nanosatellites and CubeSats: reprogrammable orbital platforms for multiple missions without hardware changes. The company serves commercial and government clients with a model that includes both spacecraft sales and payload-as-a-service, dramatically lowering the space access barrier. In 2025 it closed two significant rounds: €43M led by Founders Fund (Peter Thiel) in May, and $104M (≈€90M) in October with Google Ventures, Lux Capital, EIC Fund and Riot Ventures, bringing total raised to over $275M.
