Rebellion Defense

What Rebellion Defense does

Rebellion Defense, founded in 2019 and headquartered in Washington, D.C., is a venture-backed U.S. national-security software and sensor company. It sells what it brands as the "world's first SensorOS" - an integrated hardware-to-software stack composed of Argus (a modular, software-defined, multi-band phased-array radar miniaturized to a handheld form factor), Prism (an AI-powered sensor knowledge graph that fuses 40+ onboard and offboard feeds including radar, EO/IR, AIS and ESM into a single authoritative track with claimed 99.7% threat classification accuracy, sub-200ms latency, and tracking of 16,000+ objects simultaneously), and Iris (a multi-domain human-computer vision console for situational awareness and predictive decision support). Adjacent products include Nova (automated adversary-emulation and continuous application-security testing), Iris Extract (data extraction and ingestion for allied customers), and Mission Engineering, a custom software-development service that embeds Rebellion engineers inside customer programs.

Revenue is generated primarily through enterprise field sales of software products (Iris, Nova) on a recurring/subscription model and Mission Engineering professional services to U.S. and allied defense customers. Procurement is conducted through competitive government channels: direct contracts with military program offices (notably U.S. Navy PEO IWS), the GSA Multiple Award Schedule (MAS, awarded in 41 days), and the CDAO Tradewinds Solutions Marketplace, where Rebellion is an "Awardable" vendor. The company holds DISA Impact Level 5 Provisional Authorization for Nova on DoD networks. It operates a wholly owned UK subsidiary, Rebellion Defence, Ltd., and serves almost exclusively national-security customers: the U.S. Navy, U.S. Air Force Cloud One, U.S. Army (PEO C3T), U.S. Indo-Pacific Command, U.S. Special Operations Command, the U.K. Ministry of Defence, the Chief Digital and Artificial Intelligence Office, and the National Nuclear Security Administration, with a nascent Commercial Critical Infrastructure vertical (data centers and energy platforms) as a secondary segment.

Leadership is anchored by defense-acquisition veteran Ben FitzGerald (CEO since January 1, 2024, previously Executive Chair and an early investor since 2019), with co-founder Chris Lynch and former Interim CEO Barry Sowerwine on the Board. The company raised $150M in September 2021 at a $1B post-money valuation, is privately held, operates with 51-100 employees, and in April 2026 entered a strategic partnership with SK Telecom and Arm to co-develop Arm-based AI inference servers and a Rebellion AI chip.

Core offering

Rebellion Defense builds a SensorOS — an integrated hardware-to-software stack combining a miniaturized multi-band phased array radar (Argus), an AI-powered sensor data fusion knowledge graph (Prism), and a human-computer vision decision console (Iris) — for U.S. and allied defense and government customers. The company also sells Nova, automated adversary emulation software for cyber resilience, and provides Mission Engineering custom software development services to defense agencies.

Product overview

Rebellion Defense offers the world's first Sensor OS—a full-stack solution combining hardware and AI-powered software with operational support for defense and commercial needs. The product portfolio consists of: ARGUS (modular multi-band phased array radar for drone/hypersonic detection), PRISM (AI-powered sensor knowledge graph fusing 40+ data feeds), and Iris (human-computer vision console for situational awareness and threat response), complemented by Nova (automated security testing), Mission Engineering (custom software services), and Iris Extract (data processing module). The integrated stack transforms multi-domain sensor data into real-time decision advantage for operators.

• Shield AI: Defense AI company building autonomous systems (Hivemind) and the V-BAT drone for ISR and target recognition — directly overlapping with Rebellion's autonomous detection and battlespace-awareness mission.
• Epirus: Direct counter-UAS and counter-electronics peer; its Leonidas high-power microwave system addresses the same drone-swarm and emerging-threat problem set as Rebellion's Argus radar and Prism fusion.
• Skydio: Autonomous drone manufacturer with deep DoD adoption for reconnaissance and short-range situational awareness, competing for the same defense-AI and battlespace-awareness dollars as Rebellion's Iris/Prism stack.

Broad incumbents

• Palantir Technologies: Incumbent defense-AI / data-fusion giant (Gotham, AIP) with deep entrenchment across DoD C2 and intelligence programs — overlapping with Rebellion's Prism fusion and Iris decision-console offerings but at vastly greater scale.
• L3Harris Technologies: Major defense prime with broad portfolio in radar, sensors, and electronic systems — competes for the same sensor-fusion and integrated-air-defense program dollars as Rebellion's SensorOS.
• RTX (Raytheon): Defense prime with extensive radar, missile-defense, and sensor portfolios — directly overlapping with Rebellion's counter-drone and threat-tracking mission space at the program-of-record level.
• Northrop Grumman: Major defense prime with deep capabilities in integrated air and missile defense, sensors, and C2 — competing for the same CJADC2 and counter-air funding as Rebellion's Iris and Mission Engineering offerings.

Emerging players

• Primer.ai: Defense-focused AI platform for intelligence and multi-source data analysis, overlapping with Rebellion's Prism knowledge-graph fusion and Iris Extract capabilities for defense and intelligence customers.
