EnduroSat has announced a $104 million funding round that will expand its satellite production capabilities and fuel the company’s vision of making space data universally accessible. The round includes participation from Riot Ventures, Google Ventures (GV), Lux Capital, the European Innovation Council Fund, and Shrug Capital.
The funding coincides with the grand opening of EnduroSat’s new Space Center in Sofia, Bulgaria—a 188,340-square-foot facility designed to scale satellite manufacturing dramatically. The new center enables EnduroSat to produce up to two ESPA-class satellites daily, each weighing between 200 and 500 kilograms. The complex features advanced RF, hardware, and mechanical labs, ISO-certified cleanrooms, and full space qualification facilities.
This milestone positions EnduroSat as one of Europe’s most advanced small satellite manufacturers, addressing rising global demand for small and mid-sized satellite constellations. With its expanded infrastructure and capital infusion, the company aims to accelerate delivery cycles for constellation operators while maintaining high reliability and cost efficiency.
Founder and CEO Raycho Raychev described the expansion as a defining moment for the company, highlighting its ability to produce satellites at an industrial scale while providing customers faster access to orbit and space data solutions.
KEY QUOTES:
“We are excited to announce a $104 million funding round which will ensure significant production capability for advanced constellation players, accelerating time-to-orbit by enabling the actual production of two ESPA-class satellites per day. We are proud to welcome Riot Ventures, Google Ventures, Lux Capital, European Innovation Council Fund, and Shrug Capital to join us on our mission of streamlining access to space data.”
“This latest investment, combined with the launch of our new Space Center, marks a pivotal moment. It not only validates our strong market traction but significantly accelerates our ability to deliver highly capable, cost-effective satellite constellations at an unprecedented scale, moving us closer to a future where space data will become universally accessible and instantly available.”
Raycho Raychev, EnduroSat CEO and Founder
“EnduroSat is redefining how space infrastructure is built and deployed. Their production capabilities are aligned with the evolving demands of a new generation of satellite operators. We believe EnduroSat is uniquely positioned to empower businesses and governments to leverage the advantages of their own dedicated space assets, and we’re excited to support this vision.”
Stephen Marcus, Co-Founder and General Partner of Riot Ventures
“At GV, we believe the next era of connectivity and exploration will be fueled by scalable, modular satellite platforms. EnduroSat’s technical depth, rapid manufacturing innovation, and customer-first mindset uniquely position them to set a new standard for satellite constellations. We’re proud to support Raycho and the entire EnduroSat team as they unlock new possibilities for organizations of every size to access and leverage space data at unprecedented scale.”
Roni Hiranand, Partner at GV (Google Ventures)
“EnduroSat’s trajectory follows one of the great industrial playbooks of our time. Much like BYD began building battery components before vertically integrating into complete vehicles, EnduroSat started by building best-in-class subsystems for the space industry and has moved up the stack to now building satellites and full constellation solutions. They understand every layer of the technology stack because they built it themselves, and that deep systems knowledge translates into better performance, faster iteration, and ultimately, superior economics.”
