Skyryse, an aviation automation company focused on simplified flight controls, said it raised more than $300 million in a Series C round, valuing the business at more than $1.15 billion. The company said it has now raised more than $605 million in equity capital since its founding in 2016.
The Series C was led by Autopilot Ventures alongside returning investor Fidelity Management & Research Company, with participation from a mix of new and returning backers that included ArrowMark Partners, Atreides Management LP, BAM Elevate, Baron Capital Group, Durable Capital Partners, Positive Sum, Qatar Investment Authority, an RCM Private Markets Fund managed by Rokos Capital Management (US) LP, and Woodline Partners, among others.
Skyryse is developing SkyOS, a universal operating system for flight designed to replace conventional mechanical flight controls with an integrated hardware and software system. The company positions SkyOS as a safety-focused platform that simplifies how pilots manage aircraft during normal operations, adverse weather, and emergencies, with applicability across both civilian and defense use cases.
Skyryse said the new capital will be used to accelerate FAA certification efforts and scale SkyOS across additional aircraft platforms, including helicopters and fixed-wing aircraft. The company said the FAA granted final design approval in 2025 for SkyOS’ flight control computers, and that Skyryse is currently in FAA for-credit flight testing for the system, with formal flight verification remaining before certification.
The company highlighted a series of technology milestones it attributed to SkyOS, including automated takeoff and landing “at the swipe of a finger,” a fully automated hover, and an automated engine-out landing. Skyryse also said it was named a finalist for the National Aeronautic Association’s Collier Trophy.
Skyryse said it began development and testing on helicopters, citing their inherent instability and complexity, and cited its work integrating SkyOS onto a Black Hawk as evidence of platform-agnostic capabilities. The company said it completed integration on the Black Hawk in 91 days and demonstrated automated maneuvers, including pickup, hover, and setdown, as well as precision flight using a single-control-stick interface.
Skyryse’s technology has been deployed and tested on multiple aircraft, including the Skyryse One, which the company said is built on a turbine-powered Robinson R66. It has also flown SkyOS on a Robinson R44 and on an airplane platform, including the Cirrus SR22. The company said it has announced contracts and partnerships to integrate SkyOS across aircraft, including Airbus H-125s and H-130s, Bell 407s, Black Hawks, and Pilatus PC-12s, and cited relationships spanning military, emergency medical services, law enforcement, private operators, and international markets.
