The DoD budget exceeds $850B annually. Even a fraction of defense procurement shifting to commercial startups creates enormous TAMs. OTA (Other Transaction Authority) contracts have made it faster for startups to win government business — removing the DFARS/FAR compliance bottleneck.
The Russia-Ukraine war proved that commercial drones, satellite imagery (Starlink, Maxar), and AI-powered targeting outperform legacy defense systems at a fraction of the cost. This shifted Pentagon thinking dramatically — Anduril and Shield AI are direct beneficiaries.
The best defense tech companies build dual-use technology — products that serve both commercial and government customers. Palantir's Foundry platform serves hospitals and banks as well as DoD. This reduces customer concentration risk and improves valuation multiples.
The DoD's Replicator initiative aims to field thousands of autonomous drones by 2026. This represents an unprecedented procurement signal for drone startups — Shield AI, Joby, Skydio, and Anduril are all positioned to capture significant contract value from this program.
Defense tech (or defense technology) refers to startups building technology for national security, military, intelligence, and dual-use applications. This includes autonomous drones (Shield AI, Anduril), AI decision systems (Palantir, Primer), space technologies (Rocket Lab, True Anomaly), cybersecurity (IronNet, Dragos), and next-gen munitions. VC investment in defense tech has grown from under $1B annually in 2018 to over $30B in 2023–2024 globally.
Global VC investment in defense and dual-use technology exceeded $30B in 2023 and $35B+ in 2024, according to PitchBook and DCSA data. US-focused defense tech startups alone raised over $20B in 2024. The sector has attracted a new wave of dedicated defense tech funds including a16z's American Dynamism, Founders Fund, 8VC, and Lux Capital, alongside traditional defense contractors spinning up corporate venture arms.
The most-watched defense tech startups in 2025 include: Anduril Industries ($28B valuation, autonomous systems), Shield AI ($5B, autonomous fighter pilots), True Anomaly ($500M+, space domain awareness), Slingshot Aerospace ($1B+, space situational awareness), Sarcos ($700M, robotic exoskeletons), and a wave of drone companies including Joby Aviation, Skydio, and L3Harris-backed startups. AI-native defense companies are seeing the fastest growth.
Defense tech startups typically enter government via three paths: (1) OTA (Other Transaction Authority) contracts — faster, lighter compliance burden, used widely by SOCOM and DARPA; (2) SBIR/STTR grants — small business R&D grants from DARPA, AFWERX, NavalX, and similar programs; (3) Prime contractor partnerships — teaming with Lockheed, Raytheon, or Northrop as a sub to access existing contract vehicles. Getting a cleared CTO or BD head with existing government relationships is often the fastest entry point.
