Spire Global
US commercial smallsat operator and space data company, NYSE: SPIR. Operates the LEMUR constellation of 3U CubeSat nanosatellites collecting GNSS-RO atmospheric profiles (weather/climate), ADS-B aircraft positions (aviation), and hosted payloads for third parties (Space Services). Maritime AIS business sold to Kpler in April 2025. Headquartered in Vienna, Virginia; offices across 9 countries.
Spire Global, Inc. (NYSE: SPIR) is a US commercial smallsat operator and space data company headquartered in Vienna, Virginia, incorporated in Delaware in August 2012. The company designs, manufactures, and operates the LEMUR (Low Earth Multi-Use Receiver) constellation of 3U CubeSat nanosatellites in low Earth orbit, having deployed more than 200 LEMUR satellites since inception across 43 or more launch campaigns on ten distinct launch vehicles.[^10k-fy2025]
The LEMUR platform is a configurable nanosatellite bus providing power, pointing, data communications, and onboard processing, enabling multiple sensor payloads to operate from a common infrastructure. Two data collection technologies form the core of Spire's current commercial offering after the April 2025 divestiture of its maritime business.
The Weather and Climate product line uses GNSS Radio Occultation (GNSS-RO): onboard receivers track GPS and GLONASS signals as they refract through Earth's atmospheric limb, producing vertical profiles of temperature, pressure, and water vapor at 50 Hz sampling.[^ecmwf-spire] These profiles are assimilated by major numerical weather prediction (NWP) centres including ECMWF and NOAA's GFS, with demonstrated improvements in tropical humidity forecasts. Complementary GNSS Reflectometry (GNSS-R) yields surface-level data including soil moisture, ocean wind speed, wave roughness, and flooding extent. Spire supplies GNSS-RO data to NOAA under its Commercial Data Buy programme and to NASA under the CSDA programme.
The Aviation product line captures ICAO-standard Automatic Dependent Surveillance-Broadcast (ADS-B) signals from space, providing global aircraft position and status coverage including oceanic areas where ground-based ADS-B is absent. Amadeus selected Spire for real-time aircraft tracking data integration in May 2026.
Space Services constitutes the third pillar, offering third parties a turnkey path to orbit: Spire designs, builds, launches, and operates satellites carrying customer payloads, with access to its proprietary ground station network, cloud infrastructure, and Constellation Management Platform. Commercial customers include Lacuna Space (IoT CubeSat constellation). Government customers include the US Space Force under the STEP 2.0 IDIQ (ten-year, $237M ceiling)[^spire-stepforce] and the Government of Canada under the WildFireSat wildfire-monitoring prime contract (Can$72M, via Spire Global Canada).[^10k-fy2025] A satellite manufacturing facility opened in Munich in May 2026 to serve European sovereign customers.
Spire completed the sale of its commercial maritime AIS business, including exactEarth Ltd, to Kpler Holding SA on April 25 2025 for gross proceeds of approximately $238.9M, using the proceeds to retire all outstanding debt.[^kpler-close] Certain US federal government maritime operations were retained and not included in the sale. As of end-2025 the company had 377 employees across 9 countries, with offices in Vienna (VA), San Francisco, Boulder, Glasgow, Luxembourg, Munich (Taufkirchen), Singapore, and Cambridge (Ontario). Approximately 43% of 2025 revenue derived from three government customers per the 10-K FY2025 filing.[^10k-fy2025]
