A new generation of satellites is approaching Earth closer than ever, and Europe aims to lead this technological leap. The Spanish startup Kreios Space, whose technology enables the operation of satellites in very low Earth orbit (VLEO) — a region previously considered unreachable — has closed the largest European investment round in this field, totaling €8 million.
The round was led by the NATO Innovation Fund and JOIN Capital, with participation from Grow Venture Partners, Xesgalicia, and Tasivia Global.
Satellites operating between 150 and 400 kilometers in altitude capture images up to three times sharper than current satellites and provide direct broadband connectivity to devices, something that does not yet exist today.
Founded in 2021 by Adrián Senar, Jan Mataró, Francisco Boira, Adrià Barceló, Max Amer, and Francisco Bosch, Kreios develops VLEO satellites using its proprietary Air-Breathing Electric Propulsion (ABEP) technology, which allows them to capture atmospheric air and use it as fuel. This enables satellites to remain in orbit for years instead of days, opening opportunities with major implications for defense, connectivity, and technological sovereignty.
VLEO satellites capture images with three times the resolution of current satellites, benefiting applications ranging from wildfire detection to critical infrastructure protection. Their proximity to Earth also allows for direct broadband communications without bulky antennas, paving the way for truly global and resilient connectivity. For Europe and NATO, mastering this technology strengthens operational independence, reduces reliance on the United States, and supports ambitions to develop sovereign space capabilities.
“We are not just building satellites; we are opening an orbit that was once considered impossible,” says Adrián Senar, CEO and co-founder of Kreios Space. “Very low Earth orbit provides more precise imaging, faster connectivity, and greater independence in space. With this funding, we will demonstrate the technology in orbit and position Europe and Spain at the forefront of this new domain.”
David Ordoñez, Senior Associate at the NATO Innovation Fund, adds: “Kreios’ technology represents a decisive leap into the new frontier of very low Earth orbit. By bringing satellites closer to Earth, it enables high-resolution imaging and direct device connectivity at a level previously unattainable, a critical capability for European security.”
The round follows the €2.3 million raised by Kreios in 2024 and will fund the launch of the first two test satellites, including the first in-orbit demonstration of an ABEP engine. After this phase, the company will move toward the commercial deployment of constellations dedicated to both Earth observation and direct-to-device communications.
Based in Vigo, Kreios has grown in just four years from a laboratory project to a team of 17, backed by European investors and board members with experience at organizations such as Thales, JAXA, and the European Space Agency (ESA).
“Europe cannot be left out of the next orbital economy,” says Tobias Schirmer, founding partner of JOIN Capital. “What excites us about Kreios is the combination of its strategic importance for Europe and the fact that the technology is already mature. VLEO has been a research topic for years and is now ready for real deployment.”
Operating in VLEO also represents a unique opportunity for Spain as a nation. In this context, the CDTI and the Spanish Space Agency (AEE) have already supported the company through the Space Technology Program. With Kreios Space, Spain is positioning itself at the forefront of an increasingly strategic field.
