Rhode Island all-electric seaglider maker flying in ground effect at 180+ mph for coastal routes; YC W21 $90M Founders Fund/8090-backed with $8B+ in orders from Japan Airlines and Mesa Airlines for 2026-27 delivery.
About
REGENT is a North Kingstown, Rhode Island-based aerospace and maritime company — backed by Y Combinator (W21) with $90 million raised including a $60 million Series A co-led by 8090 Industries and Founders Fund in October 2023 with strategic investments from Japan Airlines and Lockheed Martin — developing and manufacturing all-electric seagliders, a new vehicle category that combines the speed of aircraft with the simplicity of boats by flying in ground effect (within one wingspan of the water surface) on hydrofoils, enabling 180+ mph zero-emission coastal transit over water at costs competitive with ferries. Founded in 2020 by Billy Thalheimer and Mike Klinker (MIT aerospace engineers), REGENT has secured over $8 billion in commercial orders for 500+ seagliders from operators including Mesa Airlines, Brittany Ferries, and Pacific Basin Ferry, with deliveries expected to begin in 2026-2027.
