Endel is a technology that creates personalized sound environments to reduce stress, improve sleep, and boost productivity — all backed by neuroscience and the science of circadian rhythms. The soundscapes are algorithm-powered and designed to gently rise and fall in line with immediate internal and external conditions like location, time zone, weather, and heart rate. Endel's technology is already presented as an ecosystem of products (iOS, macOS, Android apps, Alexa Skill, a standalone Apple Watch app and AppleTV) and also designed to be integrated into various hardware and platforms in mobility, hospitality, and workspaces. Major Lazer's Jillionaire, Amazon Alexa Fund, and Avex are among some of the investors in Endel.
