Reliable Robotics develops the Reliable Autonomy System (RAS), an FAA-certifiable autonomy stack designed to enable fully automated aircraft operations and prevent the leading causes of aviation accidents. The company says RAS is built to integrate with certified aircraft and existing aviation infrastructure without changes to the National Airspace System. Reliable has secured commitments for over 200 systems from commercial and military customers, been selected for the Department of Transportation’s eIPP advanced aviation pilot program, and holds a contract to provide automated air cargo operations for the U.S. Air Force. The business has been advancing FAA certification—having had its certification plans and means of compliance accepted—and is delivering required compliance materials under the FAA-agreed plan. Since its last financing the company has nearly tripled its workforce and plans to use the new $160M to expand production facilities, grow headcount, and accelerate deployment toward autonomous cargo operations in 2026. The company is headquartered in Mountain View, California and maintains a distributed global workforce.
