About
Nimbus Aerospace is a Seattle, USA-based aerospace startup founded in 2023 by Adrian Groos and Akim Niyonzima. The company is developing the N1000, a six-passenger hybrid-electric business jet targeting a 1,500-nautical-mile range and roughly 50% lower fuel burn than comparable jets. It is also building its own AI certification tool (ACT, Aircraft Compliance Tool), which uses a multi-agent architecture connected to FAA regulatory knowledge graphs to speed up compliance workflows, paired with additive manufacturing (3D printing) to cut production and certification costs. The company is currently in scaled-prototype flight testing (its quarter-scale NX1 model has flown at the Pendleton UAS Range in Oregon), targeting full-scale prototype flights in 2028 and FAA certification/customer deliveries by 2030, aimed at ultra-high-net-worth frequent flyers.
