About EnduroSat

EnduroSat is a Bulgarian space technology company founded in 2015 in Sofia, offering shared satellite missions, satellite platforms, and space-as-a-service (SaaS) for commercial and institutional customers. The company is one of Europe's fastest-growing small satellite companies and a pioneer in the shared satellite model.

EnduroSat's core offering is its CubeSat platform lineup — from 1U to 16U form factors — built with commercial-off-the-shelf (COTS) and space-qualified components. Their platforms have flown on missions for research institutions, startups, and national space programs. Subsystems include OBCs (on-board computers), UHF/S-Band radios, ADCS, EPS, and propulsion modules.

The company's shared satellite service allows customers to fly payload modules aboard EnduroSat-operated satellites, reducing the cost and complexity of reaching orbit for technology demonstrators, Earth observation experiments, and communications payloads. EnduroSat operates a growing in-house constellation providing data services and payload hosting.

EnduroSat has delivered satellites for customers in over 20 countries and has partnered with ESA, NASA, and commercial operators. The company's rapid iteration approach, low costs, and flexible deployment model have established it as a preferred platform for early-stage space companies.
