Category Standard

Elroy Air is a high-profile aerospace company with verified Series B funding (~$116M) and a reported order backlog exceeding $2B from partners like Mesa Airlines, Bristow, and LCI. The project demonstrates exceptional Technical Innovation and Real-World Utility, with a working full-scale prototype (Chaparral C1) that has achieved transition flight (vertical to forward). However, the submission itself was of very poor quality, containing false traction claims ('most people have used my product') and vague details. The final score is high due to the verified reality of the business, but significantly dampened by the lack of credible evidence in the submission and the pre-commercial nature of the hardware.

Description
Elroy Air is enabling autonomous air transport anywhere. We are developing autonomous aircraft systems to deliver goods to the world’s most remote places. Building on the powertrain and perception technology enabling the hybrid-electric/autonomous vehicle revolution, our vertical-takeoff-and-landing (VTOL) cargo transport system can operate outside of airport infrastructure and carries 200+ lbs over 300 miles. Immediate aid and relief in disaster and firefighting situations, commercial cargo by air to expand delivery options, and rapid autonomous resupply for troops in the field. Our flight and ground operations make Elroy Air's vehicles a safe, reliable, efficient way to transport cargo by air.
