What's the endgame? EnduroSat wants to bring mass production to the satellite industry, building standardised craft in large volumes rather than as one-off projects — an approach it compares to drone manufacturing. It plans standardised units weighing 200kg, 500kg, and between 1 and 5 tonnes.
The company aims to cut the cost of space data to $1 per gigabyte, a level it says would make the data affordable for small and medium businesses. Founder and chief executive officer Raycho Raychev said the goal is to "make space data accessible to more people and companies" (translated from Bulgarian).
By the numbers: EnduroSat has already put 103 satellites in orbit and delivered more than 200 craft for missions worldwide. The round ranks among the largest late-stage deep-tech deals to come out of Bulgaria, sitting in the 96th percentile of comparable rounds.
Why now? The raise follows a string of recent moves. EnduroSat pulled in €43 million in May 2025 in a Founders Fund-led round, then a further $104 million months later from backers including Riot Ventures, Alphabet's GV, and Lux Capital.
The expansion: Days before the round, EnduroSat signed a cooperation memorandum with France's ArianespaceDealroom has a profile for this one.

Part of the new capital will go toward a high-capacity production base in the US, while the company builds what it calls the EU's largest space and defence centre in Bulgaria.
The signal: EnduroSat is betting that standardisation and cheaper access to space data will drive the sector's next phase. If it delivers, the satellite industry moves closer to a manufacturing model — and Europe gains a serious homegrown player in orbital infrastructure.
