Auterion
Auterion makes AuterionOS, a vendor-agnostic drone operating system built on PX4 lineage, now fielding AI swarm and strike-kit software for NATO and Ukrainian forces.
Background
Lorenz Meier and Kevin Sartori founded Auterion in Zurich in 2017, drawing directly on Meier's prior work as the principal author of the PX4 open-source autopilot project.
The company has since relocated its headquarters to Arlington, Virginia, positioning itself inside the U.S. defense procurement orbit while retaining Swiss engineering roots.
The core product is AuterionOS, an open, vendor-agnostic operating system for autonomous drones and robots that handles fleet management, mission planning, and autonomy functions across heterogeneous hardware.
The companion Skynode line provides the edge-computing mission-computer hardware that runs AuterionOS on airframes. The company has layered AI-enabled swarming and targeting software on top of that base, culminating in the strike-kit packages now being delivered to Ukraine.
Auterion goes to market as a software and hardware module supplier to drone manufacturers, defense primes, and government customers rather than building its own airframes.
The company currently employs more than 100 people globally. Partnerships with Rheinmetall and Lockheed Martin signal a deliberate move up the defense prime supply chain.
Financial footing
- $130M Series B (Sep 2025, Bessemer)
- ~$50M DoD contract — 33,000 AI Skynode strike kits to Ukraine by end-2025
- US-HQ'd but Swiss-founded/central to EU-Ukraine drone-software story — transatlantic
- Backers: Bessemer Venture Partners
Auterion raised a $130 million Series B in September 2025 led by Bessemer Venture Partners, pushing total capital raised to approximately $167 million according to PitchBook data cited in 2025 reporting; an earlier profile put the cumulative figure at roughly $140 million, so the range is $140–167 million. The Series B was accompanied by a strategic investment from Rheinmetall, which became a significant shareholder in November 2025.
Post-round valuation was reported at north of $600 million, with one 2025 source indicating the company was exploring a subsequent round at a valuation above $1.2 billion, though that figure reflects a fundraising target rather than a closed transaction. Auterion has disclosed a $50 million Pentagon award as its largest single contract; no broader revenue or backlog figures have been made public. The company remains privately held.
Major customers & contracts
The U.S. Department of Defense awarded Auterion a $50 million contract to deliver 33,000 AI-driven drone strike kits to Ukraine, with delivery targeted by end-2025. The U.K. Ministry of Defence is listed as a confirmed defense customer. The German Bundeswehr is listed as a confirmed defense customer. The Armed Forces of Ukraine operate Auterion-powered systems in active combat.
Taiwan's National Chung-Shan Institute of Science and Technology signed a memorandum of understanding for swarm-technology integration, and a separate deal with Taiwanese firm Thunder Tiger covered software licenses on approximately 25,000 drones. The U.S. Defense Innovation Unit has been cited as a contracting entity, though that attribution comes from secondary profiling rather than Auterion's own disclosures. The German-Ukrainian joint venture Airlogix, co-founded with Auterion, is scaling autonomous drone production for Ukraine and NATO allies.

Competitive position
Against Anduril, Auterion's edge is hardware agnosticism — AuterionOS runs across third-party airframes while Anduril's autonomy stack is vertically integrated into its own Roadrunner and Ghost platforms, limiting ecosystem breadth but giving Anduril tighter hardware-software optimization. Against Skydio, Auterion focuses on open-architecture military swarming and strike applications whereas Skydio's defense work has concentrated on ISR and inspection, giving Auterion a clearer kinetic-use narrative.
Against Quantum-Systems, both are European-rooted drone-software players competing for NATO contracts, but Auterion's PX4 pedigree and larger installed base of third-party integrations give it a wider hardware ecosystem. Against proprietary autopilot stacks from legacy defense primes, Auterion's open-source lineage accelerates third-party adoption but creates IP-protection questions that primes can use against it in classified-program competitions. The broader market for drone autonomy software is fragmented; Auterion's moat is PX4 ecosystem lock-in and the scale of its Ukraine deployment as a live reference program.
Battlefield relevance
Auterion software has been confirmed in active combat operations in Ukraine. Under a $50 million Pentagon contract, the company is delivering 33,000 AI-enabled Skynode strike kits to Ukrainian forces, with the full delivery scheduled by end of 2025. Multiple 2025–2026 reports confirm AuterionOS-powered drones are operational on the Ukrainian front.
Auterion has personnel supporting Ukrainian defense efforts in the field. The Airlogix joint venture, a German-Ukrainian entity co-founded by Auterion, is scaling production of autonomous drones for Ukrainian and NATO use. No other specific combat theaters, unit designations, or operational sortie counts have been publicly disclosed.
