## About

Based in California, US, and founded in 2017, Reliable Robotics Corporation operates as an automated aircraft systems company. Robert Rose (CEO) and Juerg Frefel (CTO) are the co-founders of the company. In April 2026, Reliable Robotics Corporation raised USD 160 million in series D funding led by Nimble Partners, with participation from Island Green Capital Management, Socium Ventures, RTX Ventures, Presidio Ventures, UP.Partners, KAS Venture Partners, What If Ventures, Calm Ventures, Gaingels, and Mana Ventures, Lightspeed Venture Partners, Coatue Management, Pathbreaker Ventures and Eclipseon Ventures.

Reliable Robotics is developing aircraft automation systems for ferrying cargo and commercial aviation. The company's automation system allows for remote control of any type of aircraft and offers access to more areas. Its technology manages all phases of flying, including taxi, takeoff, landing, and parking, while qualified pilots supervise each flight remotely from a control center. It uses a certification-forward approach and has a gate-to-gate automated operation.

The company plans to use the April 2026 funding to advance FAA certification, expand production capacity, and scale deployment of its autonomous aircraft system for commercial and defense operations.
