<h2>About Odys</h2>At Odys, we’re mobilizing power, with Hybrid Power Systems developed for aerospace and in-demand everywhere. It’s the kind of mission diversity that demands a fresh way of thinking.We began with an early bet on hybrid, when the mobility industry was focused on batteries. We designed, tested, and validated our first 1 MW high-speed generator in 12 months. And then we pushed further, developing systems with greater power density in less time. Today, our Hybrid Power Systems offer outputs ranging from 20 kW to 4 MW, with applications in the air or on the ground.One of those applications is Laila, an unmanned drone designed for critical logistics and defense missions. With its 100 kW-class onboard Hybrid Power System, Laila can support medical cold-chain transport or serve as an aerial platform for counter-UAS measures.The market interest has been overwhelming: Over 30 inbound requests from leading US and global manufacturers, and 14+ DoD contracts.Our team comes from deep tech and aerospace, with backgrounds spanning drone and aircraft development, high-volume production, and electrified mobility.We operate with urgency and ownership at every level. We validated high-speed generator technology faster than our peers, not because we skipped steps, but because we've been doing this long enough to know which ones matter most.Creating the future of power, in the air and on the ground, is a challenge we’ve been training our entire lives for.
