We build the world's most potent dawn/dusk simulator.

Zeitgeber is building the first biologically authentic bedside lamp—bridging the gap between ineffective wake-up lights and inconvenient therapy lamps.

We deliver gold-standard circadian science in a premium consumer product: a naturalistic dawn simulation proven to boost energy, mood, and long-term health—no effort required.

Backed by the Center for Environmental Therapeutics (CET), we're targeting the Biohacking & Longevity markets with a functional MVP in early 2026 and a crowdfunding campaign in Q4 2026.
