Spire Maritime

What Spire Maritime does

Spire Maritime was a division of Spire Global, Inc. (NYSE: SPIR) that delivered space-based Automatic Identification System (AIS) vessel tracking and maritime domain awareness data to government and commercial customers worldwide. The unit operated as a downstream application of Spire Global's vertically integrated LEO nanosatellite constellation (LEMUR platform) and global ground station network, fusing satellite-collected AIS signals with RF geolocation and weather data to provide real-time visibility into global vessel movements, including so-called dark vessels operating without transponders.

The unit's product surface included raw AIS data feeds via API, voyage optimization partnerships (e.g., Blue Wasp / Theyr), and analytics for cargo tracking, defense maritime intelligence, and commodity trading workflows. Customer segments spanned commercial shipping, energy traders, and U.S. and allied defense and intelligence agencies. In April 2025, Spire Global divested Spire Maritime to data intelligence firm Kpler for approximately $241 million ($233.5M plus a $7.5M service agreement), with proceeds used to retire Spire Global's outstanding debt; the transaction remains under review by the UK Competition and Markets Authority, with U.S. customers including cargo trackers and the Department of Defense flagging antitrust concerns about restricted access to AIS data.

At the time of divestiture, Spire Maritime employed 51-100 staff, operated primarily through enterprise sales and API distribution, and was embedded in Spire Global's larger portfolio of weather, aviation, RF intelligence, and Space-as-a-Service offerings. Post-divestiture, Spire Global has repositioned around government, aviation, and weather verticals while expanding a sovereign European manufacturing footprint (Munich, Schaeffler partnership) and pivoting defense emphasis toward space-based reconnaissance via the Diehl Defence partnership.

Core offering

Spire Maritime provides space-based data and analytics for the maritime industry, leveraging a LEO nanosatellite constellation to deliver AIS-based vessel tracking, maritime weather forecasting, and maritime domain awareness products. Its offerings serve commercial shipping operators, defense and intelligence agencies, port authorities, and maritime analytics firms via subscription data contracts and API access. The unit benefits from Spire Global's vertically integrated satellite manufacturing, global ground station network, and AI-enhanced atmospheric profiling capabilities.

Product overview

Spire Global operates as a space-based data and intelligence company offering a unified platform of satellite-powered solutions. The core product portfolio comprises Weather & Climate Solutions (leveraging radio occultation and HyMS sensor technology), Aviation Solutions (space-based ADS-B flight tracking), and Government Solutions (RF geolocation and space reconnaissance). Supporting these core offerings are specialized sub-products including Signal Processing (voice extraction, RF fingerprinting, tip & cueing), Space Services (constellation deployment and management), DeepVision™ (weather visualization dashboard), EURIALO (next-generation aviation tracking), and AI-S2S (generative AI forecasting). The company has shifted focus away from maritime operations following the April 2025 sale of its Spire Maritime division to Kpler, concentrating instead on weather prediction, aviation intelligence, and government/defense applications.
