EnduroSat secures €43m investment to scale new Gen3 satellite production

Published: 20-Jun-2025

The Bulgaria-based satellite services company is ramping up manufacturing capacity in Europe and the US, with a new class of software-defined satellites

EnduroSat, a provider of satellite constellations-as-a-service, has announced the successful completion of a €43m investment round, led by Founders Fund, a prominent American venture capital firm. 

The funding, which also saw participation from CEECAT Capital, Morphosis Capital, and other returning investors, will support the company’s plans to scale production of its new generation of larger, ESPA-class satellites.

The new Gen3 satellites, weighing between 200kg and 500kg, mark a significant evolution for EnduroSat, building on a decade of in-orbit experience and customer collaboration. 

These software-defined, modular satellites are designed to support demanding payloads, including hyperspectral imaging, synthetic aperture radar (SAR), broadband, and navigation services.

Equipped with advanced avionics, each platform offers up to 3.5kW of peak power and data rates of 2GBPS.

Central to the new satellite’s design is a cableless bus architecture, developed entirely in-house, enabling assembly and functional testing within hours, a dramatic improvement over conventional satellite production timelines. 

This design approach is particularly suited to large constellations and responsive space operations, where rapid deployment and scalability are critical.

Delian Asparouhov, Partner at Founders Fund and co-founder and President of Varda Space Industries, said: “Raycho and his team at EnduroSat have taken a massive leap by moving away from traditional aerospace supply chains and adopting consumer electronics and automotive supply chain models. This shift gives EnduroSat a market-leading position in terms of cost-efficiency and performance, with a proven heritage of over 3,000 modules currently in orbit. The Gen3 platform positions them to address almost any space opportunity.”

The new investment will also accelerate the expansion of EnduroSat’s European and US operations. 

Notably, the company has commenced work on a 17,500 sqm facility in Sofia, Bulgaria, set to become one of the largest space R&D centres in Europe. 

The new site will house state-of-the-art satellite avionics laboratories, dual assembly lines, anechoic chambers, and expanded cleanroom capacity to support satellite integration, testing, and qualification.

By the end of 2025, EnduroSat aims to produce up to 60 satellites per month from the Sofia facility.

In parallel, EnduroSat continues to develop its US operations, including the construction of a dedicated cleanroom to service commercial and defence sector customers worldwide.

Raycho Raychev, founder and CEO of EnduroSat, said: “Our mission is to make space universally accessible because this fundamentally improves life on Earth. We’re simplifying space missions by providing the infrastructure our customers need, allowing them to focus on innovation in space-based applications. This new investment and our next-generation satellites will open up access to reliable, scalable constellations for a broader range of operators.”
