What Hemeria does

Headquartered in Toulouse with five industrial sites across France, Hemeria is a privately held aerospace and defense company founded in July 2019 as a sovereign-focused carve-out from NEXEYA. Its Space division designs and manufactures nano/microsatellite platforms (SPECTRA-L40, SPRINT-L60, SPARTA-G70), stratospheric balloons (open, pressurized, and the maneuvering BalMan system developed with CNES), and satellite equipment including composite structures, electrical harnesses, multi-layer insulation, and solar arrays. Its Defense division produces electro-optical tracking systems (HYPERIA VT, HYPERION multi-sensor EOTS), tethered aerostat surveillance systems (Jackdaw, Eagle Owl, Condor), drone airships, secure on-board electronics, power conversion systems, and through-life-support services covering PAR-NG radars across 17 systems and ILS installations at 21 French military airbases and 13 civil airports. Industrial footprint includes 4,000 sq-m of clean rooms at Toulouse and 9,500+ sq-m of lighter-than-air manufacturing capacity at Ayguesvives.

Hemeria sells primarily to French and European institutional customers, including defense procurement agencies (DGA), national and European space agencies (CNES, ESA), satellite primes and operators (Thales Alenia Space, Airbus Defense and Space, Airbus OneWeb Satellites, ArianeGroup, Astroscale, Redwire Space, KINEIS, PROMÉTHÉE, Latitude, FLYING WHALES), and security operators (Frontex, RTE). It carries France and NATO security clearances, ISO 9001, EN 9100 aerospace quality certification, and compliance with MIL STD, GAM, STANAG, AQAP, ESA/ESCC, and ASF-CNES frameworks, qualifying it for sovereign and classified work.

Revenue is generated almost entirely through negotiated B2B project contracts, long-term framework agreements (e.g., the 4.5-year CNES balloon-envelope framework, 2022-2030 SPACE INSPIRE partnership with Thales Alenia Space, the 2022-2031 VASSCO through-life-support contract covering 700 equipment items, and an 81-satellite IRIDIUM NEXT harness and structures contract worth more than €20M), hardware sales across satellite platforms and aerostat systems, and recurring through-life support and obsolescence management. Go-to-market is direct enterprise sales with two dedicated business-development heads (Space & Sky; Land & Sea) supplemented by presence at Eurosatory, the Paris Airshow, and the SmallSat Conference. The company reported €70 million of annual revenue and roughly 400 staff; in December 2025, FCDE entered exclusive negotiations to become majority shareholder alongside management and historical shareholders, accelerating inorganic and organic growth.

Scale indicators16 records

Recent moves7 records

Expansion highlights7 records

Broad incumbents

• Thales Alenia Space: Joint venture between Thales and Leonardo and Europe's largest space prime (multi-billion euro revenue). Comparable to Hemeria as a customer (SPACE INSPIRE, IRIDIUM NEXT, KINEIS, Stratobus) and a partner, but operates at vastly greater scale across the full space value chain.
• Dassault Aviation: French aerospace and defense prime with a focus on combat aircraft and unmanned systems. Comparable as a French sovereign defense prime and Hemeria's potential customer in air/space platforms, though it operates in a different primary product category.
• Safran Electronics & Defense: French defense electronics prime and Hemeria's June 2026 MOU partner for AI-powered stratospheric ELINT balloons. Comparable in French sovereign positioning and defense electronics scope, but operates at much larger scale across navigation, optronics, and avionics.
• Kongsberg Defence & Aerospace: Norwegian defense prime with space, missile, and integrated defense systems businesses. Comparable in European defense electronics, EO systems, and space subsystems, though with broader portfolio and a different home market.

Direct peers

• Beyond Gravity (formerly RUAG Space): Swiss-headquartered supplier of space structures, mechanisms, thermal protection, and satellite electronics. Direct competitor in satellite harnesses, structures, and MLI, and serves many of the same prime customers (Thales, Airbus).
• OHB SE: German mid-cap space prime (€1B+ revenue) operating in satellite systems, structures, and space equipment. Closest direct peer to Hemeria in terms of size, European positioning, and mix of small-satellite platforms, subsystems, and institutional customers.
• LeoStella: US-based joint venture between Spaceflight Inc. and Thales Alenia Space manufacturing small satellites. Direct competitor in the small-satellite constellation build-to-print and platform integration market that Hemeria serves with KINEIS and JAPETUS.
• AAC Clyde Space: UK-Swedish small-satellite platform manufacturer offering CubeSat and small-sat buses. Direct competitor in the small-satellite platform category where Hemeria sells HP-EOS, HP-IoT, SPECTRA, SPRINT, and SPARTA platforms.

Emerging players

• ICEYE: Finland-based SAR small-satellite operator and manufacturer building its own constellation. Comparable as a vertically integrated smallsat platform builder, though focused on SAR payloads; emerging as a competitor for EO constellation contracts where Hemeria's HP-EOS competes.

Others

• Airbus Defence and Space: European space and defense prime with full-spectrum satellite, launcher, and defense systems business. A Hemeria customer (OneWeb Arrow MLI, various satellite structures), it dwarfs Hemeria in scale and could in-source work packages Hemeria currently supplies.
