Nimble Partners led the round as a returning investor. New participants include Gideon Capital, RockCreek, Geek Ventures, Gold Hill Capital and Sparkwave Capital, alongside continued investment from Island Green Partners. Allen & Company supported the fundraising process. Autonomous flight designed for existing aircraft. Reliable Robotics is developing autonomous aircraft systems intended to improve aviation safety while operating with existing certified aircraft and aviation infrastructure. Its core technology comprises the Reliable Autonomy System (RAS) and Reliable Radar. The company says the systems are designed to address major causes of aviation accidents, including loss of control (LOC) and controlled flight into terrain (CFIT). Reliable's approach aims to enable commercial autonomous operations without requiring changes to the US National Airspace System. The technology is designed to support automated flight operations from gate to gate, including taxiing, takeoff, en-route flight management and landing. The company has established partnerships across the aviation sector, including with aircraft manufacturers, avionics suppliers and operators. Commercial and military applications. Reliable's autonomy technology has potential applications in both commercial and military aviation. The company said it has secured contracts with multiple branches of the US military and completed several military airworthiness review processes with the US Air Force.

Under the programme, Reliable plans to deliver cargo to small and rural communities in New Mexico and Colorado. The initiative provides an opportunity to demonstrate the technology in practical operations as the company continues pursuing certification. FAA certification for Cessna Grand Caravan. Reliable is working with the FAA to certify its Reliable Autonomy System for commercial operations on the Cessna 208B Grand Caravan. The company describes RAS as the first FAA-certifiable system designed to enable full gate-to-gate automated aircraft operation. Reliable also says it has secured FAA acceptance of its certification plan and means of compliance, as well as closed issue papers concerning continuous autopilot engagement. The system combines high-integrity navigation, full-authority flight controls and four-dimensional flight planning. Its intended capabilities include automated taxiing, takeoff, en-route navigation and landing at airports across the United States. FAA certification remains a key milestone in bringing the system into commercial service. New offices support engineering expansion. Alongside the expanded Series D round, Reliable Robotics announced the opening of new offices in Seattle, Washington, and San Diego, California. The locations will complement its existing operations in Mountain View and San Martin, California, and Albuquerque, New Mexico. The company plans to recruit across engineering disciplines and establish a centre of excellence for its radar programme in Seattle. Reliable said its workforce has grown to more than 250 employees and that it is continuing to recruit across its office locations. The additional funding, expanded facilities and hiring plans are intended to help Reliable advance certification work while scaling production of autonomous aviation systems for commercial and defense applications.

Reliable Robotics secures $115M to advance autonomous aviation. 21 October 2026 Key Takeaways * Reliable Robotics has secured $115 million in additional capital, pushing its valuation above $1 billion. * The financing expands its Series D to $275 million, including $90 million in equity and $25 million in debt. * The company will expand aircraft production, engineering teams and efforts to secure FAA certification. Reliable Robotics secures $115M in Series D extension. Reliable Robotics has secured a $115 million funding round to develop its autonomous aircraft technology. Mountain View-based Reliable announced the new funding on 20 October. The financing increases the series D funding round to $275 million and values the company at more than $1 billion. Nimble Partners, a repeat investor, led the equity financing. The funding round also consists of $90 million in equity and a $25 million term loan from Silicon Valley Bank. New investors such as Gideon Strategic Partners, Rock Creek, Geek Ventures, Gold Hill Capital, and Sparkwave Capital also participated. Island Green Partners also invested once more. The company has accumulated over $380 million in equity funding to date. It intends to scale up its aircraft fleet and production facilities. The funds will also help accelerate engineering hiring and advance technology development. Crossing the billion-dollar valuation threshold is a major achievement. Autonomous flight technology targets aviation safety. Reliable Robotics' core technology combines the Reliable Autonomy System with its proprietary radar. The system is designed to manage aircraft operations from gate to gate. Its capabilities include taxiing, take-off, flight management and landing. The technology targets major aviation accident risks. These include loss of control and controlled flight into terrain. High-integrity navigation, automated flight controls and four-dimensional flight planning support its safety approach. Reliable is pursuing Federal Aviation Administration certification for commercial operations on the Cessna 208B Grand Caravan. Its continuous autopilot engagement system is the first stage. CEO Robert Rose expects certification for this capability within 18 to 24 months. A later stage would allow pilots to operate aircraft from ground-control stations. Rose estimates that approval remains at least three years away. The company is also developing solid-state radar designed to improve collision detection. Rose expects radar certification by the end of 2027. Government partnerships support commercial development. Reliable Robotics is advancing autonomous aviation through government contracts, military partnerships, and FAA pilot programme participation. These initiatives support operational testing and potential commercial expansion across regional cargo routes. Source: Created by Ventureburn. Reliable Robotics is pursuing opportunities across commercial and military aviation. The company has secured contracts with multiple branches of the US military. It has also completed several military airworthiness review processes with the US Air Force. Its selection for the FAA's Advanced Air Mobility Integration Pilot Program supports pre-certification operations. These flights will deliver cargo to smaller communities across New Mexico and Colorado. The programme offers opportunities to demonstrate the technology under operational conditions. These activities provide operational experience alongside certification efforts. The company's technology is designed for existing aircraft rather than entirely new airframes. This approach could reduce barriers to adoption if regulators approve commercial deployment. Nimble Partners founder John Burbank said the opportunity extends beyond building a single autonomous aircraft. He believes the technology could eventually support different aircraft types. However, broad adoption will depend on certification outcomes and operational reliability. Reliable Robotics expands engineering and production capacity. The fresh funds will be used to accelerate the company's growth phase. Reliable Robotics has established new offices in Seattle, Washington, and San Diego, California. It also supports operations in Mountain View, San Martin and Albuquerque. Today the company has over 250 employees. It will continue hiring throughout engineering, and open a radar centre of excellence in Seattle. In addition, increased production capacity will accommodate the company's expanding aircraft programme. Reliable Robotics. Certification timelines may impact the pace of commercial deployment and revenue generation. Nevertheless, its expanded financing provides additional resources for engineering and operational development.
