To get there, we start with our UAV called Laila for commercial logistics, medical transport, humanitarian aid, disaster relief, and defense missions. We're deploying aircraft with launch partners (Fiji Airways, Honeywell, Aramex, US Navy) beginning in late 2025 and already have firm orders for aircraft under contract. We're a team of expert engineers from deep tech and aerospace that focus on fast iterations loops (completed transition flight faster than our peers) combined with mastery of the aircraft certification process.
