Zeo launched in 2009 with a consumer EEG headband that tracked sleep cycles—measuring deep sleep, REM, and light sleep. The product was scientifically validated and genuinely innovative. Users wore the headband at night and received a "sleep score" each morning. The Quantified Self movement embraced Zeo enthusiastically.

Zeo was too early. In 2009-2013, consumers weren't accustomed to wearing devices to bed for health data. The headband, while functional, was less comfortable than the wrist-worn trackers that came later. The market for sleep tracking wouldn't mature until Fitbit, Apple Watch, and Oura Ring made health wearables mainstream—years after Zeo was gone.
Key Lesson
Being 5-10 years early is the same as being wrong. If the market doesn't exist yet, you'll run out of money before it arrives. Timing matters as much as product quality.
