Auterion, the Swiss-American drone software company behind the open-source PX4 autopilot system, has secured $130 million in Series B funding led by Bessemer Venture Partners to accelerate deployment of AI-powered drone swarms for military operations. The funding round values the Arlington, Virginia-based company at “north of $600 million” according to Bloomberg.
The funding comes as Auterion fulfills a $50 million Pentagon contract to deliver 33,000 AI-enhanced “strike kits” to Ukraine, representing one of the largest autonomous technology deployments to date.
Pentagon backing validates combat-proven drone OS
Founded in 2017 by Dr. Lorenz Meier, creator of the widely-adopted PX4 autopilot standard, Auterion has evolved from an academic drone project at ETH Zurich into a defense technology provider with approximately $100 million in annual revenue. The company’s AuterionOS platform transforms individual drones into coordinated swarms capable of autonomous operations even under heavy electronic warfare conditions.
“We’re software – simple, for everybody,” Meier said in an interview. “Our open approach is what the customer wants and needs.”
Auterion’s technology currently operates in active combat zones across Ukraine, where the company maintains personnel supporting Ukrainian defense efforts. The platform’s combat validation has attracted partnerships with major defense contractors including Rheinmetall and Taiwan’s military.
Open architecture challenges proprietary drone platforms
Unlike competitors that use proprietary systems, Auterion’s approach centers on open architecture interoperability. The company’s Skynode hardware can retrofit existing drone platforms with AI-powered autonomy, swarm coordination capabilities, and jamming-resistant communications.
Bessemer Venture Partners led the financing round, which includes existing Auterion investors Lakestar and Mosaic. The company said it will use the fresh money for both internal and external expansion, planning to add teams and open new offices as well as acquire companies making applications that work with its drone system.
Swarm software enables coordinated strikes
Auterion’s software enables single operators to coordinate multiple drones across different manufacturers’ platforms. The technology allows autonomous navigation, target recognition, and mission completion even when GPS and communication links are disrupted – capabilities proven essential in Ukraine’s electronic warfare environment.
The company, based in Arlington, Virginia, is “close to” $100 million in revenue and has turned cash flow positive, according to CEO Meier. Auterion plans to expand operations across Europe, with contracts with two additional European countries expected to be announced soon.
Meier said the company would announce contracts with two European countries “soon,” without offering details. The startup also announced a partnership with German defense company Rheinmetall AG to develop software for drones, though Meier declined to provide details about the partnership.
DroneXL’s Take
Auterion’s funding success reflects a fundamental shift in military drone strategy – from expensive, specialized platforms toward mass coordination of affordable, AI-enhanced systems. The company’s open-source foundation and battle-tested deployment give it credibility that many defense tech startups lack.
The $600+ million valuation seems reasonable given Auterion’s $100M revenue run rate and proven combat effectiveness. Most intriguingly, the open architecture approach could democratize advanced autonomous capabilities for smaller allied nations lacking resources for proprietary systems.
