Spire Global

What Spire Global does

Spire Global is a space-to-cloud data and intelligence company that designs, manufactures, and operates its own low-Earth-orbit nanosatellite constellation to deliver weather, aviation, and radio-frequency (RF) data to government and commercial customers. The company's proprietary LEMUR (Low Earth Multi-Use Receiver) platform supports a constellation of 100+ active satellites with 600+ combined years of flight heritage, and the firm runs vertically integrated manufacturing in Glasgow, Boulder, and a new Munich clean room capable of producing 300-400 satellites per year. Differentiated technology assets include GNSS radio occultation profiling, the HyMS hyperspectral microwave sounder, space-based ADS-B processing 300M+ messages daily, single-satellite RF geolocation across VHF to X-band, and the AI-S2S generative AI weather model that independently outperforms ECMWF by 14.2% in the 3-6 week forecast range. Customers span US Federal agencies (NOAA, NGA, NRO, US Armed Forces via Spire Federal), the European Space Agency, NATO-aligned defense customers, and commercial enterprises including Amadeus, Deloitte, Chevron, and Amazon Air.

Spire monetizes through three primary streams: subscription data services delivered via REST APIs and event streams (aviation, weather, RF); multi-year Space-as-a-Service contracts covering Software-in-Space, Payload-in-Space, Solution-in-Space, and Operations-in-Space offerings on the LEMUR bus; and direct government contracts for mission-specific data and satellites. Distribution combines a self-serve developer portal motion with a direct enterprise field sales team organized by region (North America, Europe, South America, Africa, Asia). Pricing is largely quote-based subscription, with billing cadences of monthly for APIs and multi-year for Space Services programs.

The company's strategic positioning has shifted materially following the April 2025 divestiture of its maritime business (built around the 2021 exactEarth acquisition) to Kpler for $238.9M, which resolved an L3Harris dispute and refocused the platform on space-based intelligence for defense, weather/climate, and aviation. In 2026, Spire is executing a defense-led growth strategy anchored on a Munich sovereign manufacturing footprint, partnerships with Schaeffler and Diehl Defence, and an expanded leadership bench drawn from the US military and intelligence community. Headcount sits in the 251-500 range, the company is publicly traded on the NYSE under SPIR with a $675M market capitalization as of June 2026, and 2025 revenue was $71.6M with 2026 guidance of $75-85M.

Core offering

Spire Global designs, manufactures, and operates a proprietary low-Earth orbit (LEO) nanosatellite constellation (the LEMUR platform) to collect space-based data and deliver weather, aviation, RF geolocation, and Earth observation data products to government and commercial customers via APIs and data subscriptions. The company also offers Space-as-a-Service, enabling customers to deploy custom payloads and software on its LEMUR satellite bus through tiered service offerings.

Product overview

Spire Global operates a vertically integrated space-to-cloud data platform providing actionable intelligence through satellite-based Earth observation and analytics. The core LEMUR satellite constellation (100+ satellites with 600+ flight years heritage) supports multiple product lines: Aviation data (ADS-B flight tracking via Flights Live API and Events Stream API), Weather & Climate intelligence (AI-S2S forecasting, DeepVision dashboard, Energy Trading Intelligence), Space Reconnaissance (RF geolocation, signal processing), and Space Services (satellite-as-a-service offerings). Key differentiated products include the AI-S2S generative AI weather forecasting (outperforming ECMWF by 14.2%), HyMS hyperspectral microwave sounding, EURIALO GNSS-independent aviation tracking, and the Constellation Management Platform for customer satellite operations. The company offers public APIs for aviation, weather, and space services data access, with manufacturing facilities in Glasgow, Boulder, and Munich capable of producing 300-400 satellites annually.

Recent moves7 records

Expansion highlights7 records

Emerging players

• GHGSat: Operates a constellation of satellites purpose-built for greenhouse gas and methane detection, with a similar commercial subscription model and oil & gas/utility customers. Adjacent competitor in the satellite-derived emissions intelligence vertical Spire also serves.
• Capella Space: US SAR satellite operator selling on-demand high-resolution imagery to defense, intelligence, and commercial customers. Comparable as a vertically integrated smallsat data business pursuing the same DoD/IC and commercial RF/EO wallet.
• Rocket Lab USA: Public space company operating small launch services and a satellite business (including acquisitions like SolAero and SincLair). Comparable as a vertically integrated small-sat platform provider and Space Services competitor.

Direct peers

• Planet Labs PBC: Public Earth-observation operator flying its own constellation of small satellites to deliver daily imagery and analytics to government and commercial customers. Direct comparable on LEO data monetization, government GTM, and recurring subscription economics.
• Satellogic: Public low-earth-orbit Earth observation company building its own constellation for high-resolution imagery and analytics, targeting government and commercial customers. Closely analogous to Spire on vertically integrated nanosatellite design and asset-light business model.
• BlackSky Holdings: Provides real-time geospatial intelligence through a proprietary small-satellite constellation, with a defense and intelligence focus similar to Spire Federal. Directly comparable in cadence-driven imagery, RF/EO analytics, and government contracts.
• ICEYE: Operates the largest commercial SAR satellite constellation, selling imagery and data subscriptions to defense, maritime, and insurance customers. Comparable as a vertically integrated small-sat operator competing for the same EO and government budgets.

Broad incumbents

• Airbus Defence and Space: European prime contractor with satellite manufacturing, Earth observation, and sovereign space programs. Highly comparable to Spire on European defense RF/sensing opportunities and a direct competitor for Diehl/EU defense contracts.
• Iridium Communications: Public operator of a global LEO satellite constellation providing voice and data services to government, maritime, aviation, and IoT customers. Comparable as a scaled LEO operator with subscription ARR and a strong government/DoD channel.
• Maxar Technologies: Large incumbent provider of high-resolution Earth observation satellites and geospatial intelligence to US and allied governments. Overlaps with Spire on aviation/weather/RF data products but at much higher price points and a slower delivery cadence.
