Documented cause
Spire Health raised $7.5M to develop a clip-on wearable that detected stress through breathing patterns, tracking respiratory rate to alert users to tension. The device sold for $149 and received positive press but failed commercially. User retention was extremely low as the novelty wore off after initial weeks, and the breathing-based stress detection had high false-positive rates that frustrated users. The company ceased operations in early 2020 as COVID disrupted its supply chain and B2B sales pipeline collapsed.
