In an industry obsessed with speed and range, one German startup is betting that the future of aviation isn't about the engine—it's about the lightbulb. JetLite is engineering cabin lighting that does more than illuminate; it recalibrates human circadian rhythms at 30,000 feet.

"They're not selling lights—they're selling alertness, comfort, and a competitive edge for airlines."

The tech stack reveals a modern, scalable approach. React for the frontend, Zendesk for customer support, and Sentry for monitoring—standard tools for a company that needs to move fast without breaking things. The use of Priority Hints and Lazy Loading shows they're optimizing for performance, even on their marketing site. But the real question is: can they scale from a $7.3M revenue to a $70M one? The aviation industry is notoriously slow-moving, and adoption cycles are long. JetLite's success hinges on proving ROI through data—specifically, how their lighting improves passenger satisfaction scores or reduces crew fatigue.

• Bootstrapped to $7.3M revenue—no VC dependency
• Focused on B2B aviation—no consumer distraction
• Science-first approach—circadian lighting as a product differentiator
• Lean team of 37—high efficiency, low overhead
• Modern tech stack—built for scalability
