Sleep Cycle

Göteborg, Sweden

Sleep Cycle is a leading sleep technology company that leverages sound analysis, advanced AI, and 15 years of scientific research to help users track, understand, and improve their sleep. The app uses smartphone sensors to monitor sleep duration, wake frequency, and sleep stage dynamics—light, deep, and REM—without requiring wearables. Its proprietary Sleep Score is built on three research-backed pillars: Routine (sleep regularity), Quality (continuity and depth of sleep), and overall well-being. The company has pioneered innovations such as the smart alarm patent (US Patent 8493220) and introduced features like Cough Radar, which detects community-level illness outbreaks through sleep-related coughing patterns. Sleep Cycle also launched Luma, an AI-powered sleep coach that provides personalized insights and guidance based on long-term sleep data, all within a secure, health-data-protected framework.
