Eight Sleep, the New York sleep technology company known for its smart Pod mattress system, has raised 50 million dollars in fresh funding at a 1.5 billion dollar valuation, accelerating its shift into AI-powered predictive sleep and preventive health.
The round, completed on 4 March and led by Tether Investments with participation from HSG, Valor Equity Partners, Founders Fund and Y Combinator, takes the company's total funding to more than 310 million dollars.
The company's current Pod tracks biometrics such as sleep stages, heart rate and heart rate variability, then adjusts temperature and elevation during the night - a system Eight Sleep describes as reactive technology. Now it is developing an AI-powered predictive sleep agent that simulates thousands of scenarios, from a warm bedroom to late exercise or high stress, and adjusts the sleep environment before the user even gets into bed.
Eight Sleep says its models are trained on more than one billion hours of real-world sleep data from users in over 35 countries, giving it what it calls an unmatched physiological dataset. In early trials, almost half of participants changed behaviour such as activity timing, caffeine intake or sleep schedules in response to automated, AI-driven guidance.
Alongside its AI-powered predictive sleep push, the firm is advancing US clinical and regulatory work, including Food and Drug Administration filings for detecting and mitigating sleep apnoea. FDA clearance would effectively move the Pod from a wellness device to a regulated health platform capable of screening and intervening at scale, passively, every night.
"Sleep was just the beginning. We've built the most advanced AI-powered health sensing system in the world - one that learns your body better every night and acts on that knowledge," said co-founder and chief executive Matteo Franceschetti, adding that the goal is to build "the defining health technology company of this generation."
For backers such as Tether, Eight Sleep's AI-powered predictive sleep technology is part of a broader bet that personalised, on-device intelligence will help people better understand recovery, longevity and long-term health. If the company can turn its smart mattresses into regulated tools that anticipate problems before they surface, its latest funding round may mark an early step in a wider shift toward human-first, AI-driven health platforms.
