What's the endgame? REGENT builds Seagliders — high-speed, hydrofoiling wing-in-ground effect craft that operate over water. Its platform spans passenger vessels like Viceroy and autonomous drone systems like Squire, targeting both commercial and defense markets.
What's the money for? The company plans to scale manufacturing, hit certification milestones, expand engineering, advance its commercial and defense pipelines, and deliver Seagliders to customers.
Why now? The investor list signals dual-use ambition. Lockheed Martin Ventures and Japan Airlines back opposite ends of the pipeline — one defense, one commercial aviation — while chief executive officer Billy Thalheimer frames REGENT as improving maritime mobility.
The signal: At $240 million, this ranks among the largest US hardware Series B rounds on record — roughly the 98th percentile across 1,337 comparable deals. That scale of capital for capital-intensive, pre-certification hardware shows investors are willing to fund long-cycle transport bets, especially those that straddle commercial and military use.
