Eight Sleep, a New York–based “sleep-fitness” startup, just closed a $100 million Series D funding round led by HSG with participation from Valor Equity Partners, Founders Fund, Y Combinator, and high-profile figures like Formula 1’s Charles Leclerc and McLaren CEO Zak Brown. The investment will accelerate development of its AI-powered “Sleep Agent” platform—leveraging digital twins and large-language models to deliver predictive, personalized adjustment of temperature, elevation, and other sleep variables—while also supporting expansion into medical applications (notably sleep apnea and menopause relief), pursuing FDA clearance, boosting global reach including retail showrooms, and potentially nearing unicorn status after already surpassing $500 million in Pod sales.

In-Depth
Eight Sleep is rewriting what it means to “sleep smart.” With its $100 million Series D injection, the company is no longer just tracking snore-patterns and heart rates—it’s designing an AI that actually intervenes. The Sleep Agent, powered by large-language models and digital twin simulations, works pre-emptively: adjusting your bed’s temperature, elevation, and comfort settings in real time, aiming to tailor your environment to what your body needs before you even feel it.
But it doesn’t stop at optimizing comfort. The Pod is evolving into a serious health platform—one that could someday be prescribed. FDA clearance for menopause and sleep apnea interventions is in the works. That’s a notable move into regulated medicine, dialing in to conditions that affect millions yet remain underserved in existing sleep tech.
Selling predominantly online until now, Eight Sleep is also preparing a retail breakout. Storefronts are slated to open soon, offering an in-person experience of its unique “sleep fitness” solutions. Alongside international expansion—to markets such as China and broader Asia—this push aims to reframe the Pod from a gadget for tech billionaires to a health asset for everyday people like teachers or doctors.
It’s already reached impressive milestones: more than half a billion in Pod sales, ten-fold revenue growth, and analysis of over a billion hours of collected sleep data. Now, as it edges toward unicorn status, Eight Sleep is staking its claim at the crossroads of AI, wellness, and personalized healthcare—turning the simple act of rest into a data-driven frontier.
