The funding round will enable EnduroSat to further scale production of its modular satellite buses, with the new facility capable of manufacturing up to two ESPA-class satellites per day.
EnduroSat, a provider of satellite constellations-as-a-service, has announced a new investment exceeding $100m from Riot Ventures, Google Ventures (GV), Lux Capital, the European Innovation Council Fund and Shrug Capital. The funding marks EnduroSat's second major round this year, reinforcing the company's strong market momentum and rapid growth. The announcement coincides with the official opening of EnduroSat's new 188,340 sqft Space Centre, a cutting-edge facility designed to dramatically scale the production of its Frame ESPA-class satellites.
The investment and expansion come amid surging global demand for small and medium-sized satellite constellations, which typically range from dozens to hundreds of satellites -- smaller and more agile than mega-constellations such as Starlink or Kuiper. These adaptable networks are increasingly sought after by governments, commercial organisations and research institutions looking to establish private communications systems and earth observation capabilities.
EnduroSat's latest generation of Frame satellites is designed to meet this demand efficiently. The ESPA-class buses feature a cableless design that enables assembly and testing within hours, significantly improving the speed, flexibility and cost-effectiveness of deploying satellite missions and constellations.
Raycho Raychev, Founder and CEO of EnduroSat, added: "Our mission at EnduroSat is to simplify and streamline access to space, making space data a powerful tool for innovation across all industries. 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."
To meet growing customer demand, EnduroSat's new state-of-the-art Space Center is designed to enable the high-volume production of up to two 200-500kg satellites per day. The facility features extensive labs, including advanced RF labs, Hardware and Mechanical labs, ISO-classified clean rooms and comprehensive space qualification facilities, delivering cutting-edge speed, reliability and cost-efficiency in satellite manufacturing.
Investors in the funding round offered their support for EnduroSat's momentum and vision.
Stephen Marcus, Co-Founder and General Partner of Riot Ventures, said: "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."
Roni Hiranand, Partner at GV (Google Ventures), added: "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 organisations of every size to access and leverage space data at unprecedented scale."
Brandon Reeves, Partner at Lux Capital, stated: "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."
