About Eight Sleep

Eight Sleep is a technology company specializing in sleep solutions. Founded by Matteo Franceschetti and Alexandra Zatarain, the company develops innovative products that integrate artificial intelligence, sensors, and algorithms to optimize nocturnal rest based on real-time physiological data.

The Core Product: The Pod

At the heart of Eight Sleep’s offerings is the Pod, a cover installed over the bed that adjusts body temperature throughout the night. The device collects data on heart rate, variability, sleep cycles, and breathing patterns, automatically modifying the thermal environment to promote uninterrupted and more efficient sleep.

Machine Learning for Personalized Sleep Experience

Eight Sleep has developed a machine learning model to tailor the experience for each user. The nightly data collected feeds into a predictive analysis system that enables the bed to learn individual user patterns.

  • Benefits: This results in reduced sleep latency, increased time in deep sleep phases, and fewer interruptions.

AI Conversational Models for Personalized Sleep Agents

Recently, Eight Sleep began integrating conversational AI models to create personalized sleep agents or assistants that interact with users, provide recommendations, and make automatic adjustments based on defined health goals.

Alexandra Zatarain’s Vision

According to Alexandra Zatarain, co-founder and Chief Marketing Officer at Eight Sleep, “Sleep technology is now part of holistic well-being. Sleep cannot continue to operate with passive methods when dynamic intervention is enabled by data.”

Eight Sleep’s Vision and Expansion Plans

The company aims to transform the bed into a medical device that constantly monitors health-related variables. With over $160 million in investment, Eight Sleep is present in the United States and plans to expand to Latin America, focusing on Mexico. Unlike traditional mattress brands, Eight Sleep positions itself as a health technology and prevention solution.

  • Strategic Partnerships: Their strategy includes alliances with athletes, specialized clinics, and high-performance corporations. The product development team collaborates with sleep neuroscience experts, sports medicine doctors, and longevity specialists to scientifically validate system functions.
  • Continuous Improvement: Each software update aims to improve energy efficiency, sensor precision, and predictive capabilities. The company is also working on developing new categories, such as smart bed clothing and integrated systems with medical wearable devices.
