Eight Sleep Raises $100M to Advance AI-Powered Sleep Technology

Eight Sleep raises $100M to expand it AI-powered sleep tech | TechCrunch

Roughly one in three adults in the U.S. regularly gets insufficient sleep, driving demand for tools that can monitor, analyze, and enhance rest. Eight Sleep, founded in 2014, offers AI-powered sleep tech products that promise to transform your bed into a preventive health device. The New York-based startup announced Tuesday that it raised a fresh $100 million round from investors such as HSG, Valor Equity Partners, Founders Fund, Y Combinator and athletes including Ferrari F1 driver Charles Leclerc, and Zak Brown, who is the CEO of McLaren F1. With this round, Eight Sleep has raised roughly $260 million total, Pitchbook estimates. It previously raised an $86 million Series C in 2021 by investors who assigned it a $500 million post-money valuation. Eight declined to reveal its current valuation. "If we successfully execute our AI roadmap, launch internationally, and develop condition-specific interventions, achieving unicorn status will naturally follow," Alexandra Zatarain, co-founder and CMO of Eight Sleep, told TechCrunch. Eight offers smart mattresses that integrate software and AI to track and enhance sleep quality. Its flagship product, Pod, offers features like measuring sleep stages, heart rate, breathing patterns, and movement. Using these insights, it automatically adjusts temperature, elevation, and firmness. It can also detect snoring and automatically elevate the base in response, according to the company. The company has generated more than $500 million in Pod sales, expanded its revenue tenfold since launching the product in 2019, and collected insights from over one billion hours of recorded sleep data, it says. Eight, which employs just over 100 full-time staff, is now expanding beyond the Pod with its Sleep Agent, an AI-driven system that leverages large language models to create thousands of digital twins for each user and predict outcomes, with the goal of optimizing nightly recovery. This approach shifts sleep technology from reactive tracking to proactive, personalized intervention, said Zatarain. The sleep tech market features a range of competitors, from wearable devices such as Oura, Fitbit, and Apple, to medical-focused companies like ResMed, as well as smart mattress and sleep surface makers, including Sleep Number and ChiliSleep. Eight's core differentiator, Autopilot, "builds a personal blueprint from night one, then adapts continuously, accounting for seasonality, travel, stress, training, illness, or even a bad night before. And it works independently for each side of the bed," Zatarain said. The startup plans to use the new funding to accelerate its growth in the medical sector, building on the Pod's health-monitoring capabilities. With the introduction of Health Check, the system can monitor cardiovascular and respiratory patterns with up to 99% accuracy without the need for wearable devices, according to the company. "We're not replacing your doctor, but we are giving you nightly, high-accuracy health monitoring so you can act early if trends shift. Over time, this data can complement medical care," Zatarain said. Eight's recently launched Hot Flash Mode employs AI-driven cooling to relieve menopause symptoms. It is also working on contactless solutions for sleep apnea. The company is pursuing FDA approval and will utilize the Pod's real-time biometric monitoring to deliver personalized interventions. Eight Sleep currently ships to over 30 countries -- including Canada, the UK and EU nations, Australia, Mexico, and the UAE -- and is now planning to expand into China. The CMO told TechCrunch that China, as one of the world's largest consumer markets, is seeing a rise in a health-conscious middle class that prioritizes sleep and overall wellness. Regarding sensitive health data, Zatarain said the company complies with each locale's regulations, including for data storage. "Privacy is foundational. All data is encrypted, never sold, and fully private. We comply with GDPR and CCPA, and unlike many devices, we don't use microphones. Our biometric sensors are embedded in the bed surface -- no wearables, no invasiveness, just passive, high-accuracy insights," Zatarain said.

Eight Sleep Lands $100M In Fresh Funding To Help You Get A Better Night's Rest

Eight Sleep, a startup developing "sleep fitness" products, announced Tuesday that it has raised $100 million in a new funding round. Led by HSG, the Series D also got some participation from Valor Equity Partners, Founders Fund, Y Combinator and a number of sports figures, including Ferrari F1 driver Charles Leclerc and McLaren Racing CEO Zak Brown. Other backers include Khosla Ventures, SoftBank and actor Kevin Hart. The capital infusion brings the New York-based startup's total funding to over $260 million, per Crunchbase data. Eight Sleep declined to reveal its valuation, but it was valued at approximately $500 million at the time of its last raise -- an $86 million Series C round announced in August 2021. "We're focused on growth, global expansion and the medical space," Matteo Franceschetti, CEO and co-founder, told Crunchbase News. "If we execute on our AI roadmap, international launches and condition-specific interventions, unicorn status will follow naturally." Founded in 2014, Eight Sleep describes itself as a "sleep‑fitness company" that combines technology, physiology and data "to unlock deeper sleep and better health." The company started out selling a smart mattress, or Pod, that uses embedded sensors to collect data and study trends about how people sleep. One could say the company was ahead of its time -- in 2018, it launched an AI-powered sleep coach that tells users things like: "Last night, you slept 40 minutes less than your average this month" or "This week, your REM sleep is lower than average. Try going to bed 30 minutes earlier tonight." "Unlike others in the space, we don't just sell a bed," said Alexandra Zatarain, co-founder and VP of marketing. The Pod does things like adjust elevation, sound and wake-up in real time based on a person's needs, she said. It does that in part with the help of a smart bed cover with features such as an automatic temperature adjustment. "We also passively monitor key health metrics with clinical-grade accuracy, without requiring you to wear anything," Zatarain added. Over time, Eight Sleep has continued to expand its offerings. Today, the company also sells a software membership attached to its Pod. And, it's built a number of products aimed at offering "different solutions to different sleep problems." For example, earlier this year, it introduced its first in a line of supplements developed with Dr. Peter Attia, co-founder and chief medical officer of Biograph, which are designed to help people sleep better without prescription medications. While Eight Sleep declined to reveal hard revenue figures, its founders said its revenue has grown 10x since 2020, with its Pod generating over $500 million in revenue to date. It also says the company was free cash flow positive in first half of 2025. Looking ahead With customers in over 30 countries including Australia, the United Kingdom, Australia, Mexico and the United Arab Emirates, Eight Sleep is now eyeing the China and Singapore markets. Eight Sleep also plans to use its funding "to supercharge" AI roadmap, starting with the development of a sleep agent that interprets biometric data and simulates thousands of digital twins per user, allowing it to predict outcomes through advanced modeling. The agent then, the company claims, "intelligently" adjusts variables like temperature, elevation, and bedtime routines to optimize recovery on a nightly basis. This builds on the company's existing Autopilot feature, which the company says makes "millions" of nightly adjustments based on user behavior and biofeedback. The funding will also support Eight Sleep's entry into the medical space. Building on the Pod's health‑monitoring capabilities, which track cardiovascular and respiratory patterns, the company said it is developing AI-powered solutions for medical sleep challenges, starting with menopausal sleep and sleep apnea. It is also targeting FDA approval for certain applications. Presently, Eight Sleep has just over 100 full-time employees, a number it plans to grow with its new capital. Eight Sleep is not the only sleep-focused company to raise capital as of late. Over the past couple of years, investors have poured hundreds of millions of dollars into an array of companies working on treatments for sleep-related ailments and technology to help improve sleep quality. Oura, maker of the popular wearable rings that record and analyze biometric data, is the largest investment recipient in this area. It's raised $348 million in equity funding to date, including a $200 million November Series D.

Silicon Valley Throws $100M at AI-Powered Mattress With a Subscription - Decrypt

Celebrity fan club includes Elon Musk, Mark Zuckerberg, and Scarlett Johansson -- while Reddit calls it a "glorified water bed" Eight Sleep, a startup that sells $3,000 AI-powered mattresses with a monthly subscription fee, just raised $100 million in Series D funding, hoping to bolster a relatively novel idea within the consumer discretionary sector. The round -- led by Founders Fund, Y Combinator, Valor Equity Partners, and HSG (formerly Sequoia China) -- also drew investments from F1 driver Charles Leclerc and McLaren Racing CEO Zak Brown. The deal pushes the company's valuation to about $500 million, with more than $500 million in Pod sales reported since launch. Eight Sleep's "Pod" system uses water-filled tubes in a mattress cover to adjust bed temperature between 55°F and 110°F (13-43 °C). Built-in sensors track heart rate, breathing, and heart rate variability, which an AI system called Autopilot uses to tweak the environment in real time. Prices start at $2,500 for the mattress topper, and climb over $4,000 for the whole system. Then there's a $17-$25 monthly subscription for "advanced features" -- because yes, even your mattress now needs a membership plan. The company has amassed a high-profile fan base, including Elon Musk and Mark Zuckerberg. Scarlett Johansson swears by it, and biohacker Bryan Johnson, who spends $2M a year on anti-aging, is another user. "This new funding enables us to accelerate the deployment of AI for sleep optimization, expand into medical applications like menopausal sleep and sleep apnea, and bring our technology to millions of people around the world," CEO Matteo Franceschetti said in the announcement. The former lawyer, turned sleep obsessive, founded the company in 2014 after struggling with his own sleep issues. But not all the feedback has been positive. On social media, users have shared stories about glitches that cause the system to stop working entirely, leaving them with an expensive, non-functional bed. Others have reported issues with water leaks and connectivity problems. Eight Sleep's new funding will support the development of what it calls a "Sleep Agent," an AI that will run thousands of nightly simulations to further refine a user's rest. The company is also seeking FDA approval for medical applications of its technology, including treating menopausal hot flashes and sleep apnea.. The company says its AI models have processed over 1 billion hours of sleep data. With $100 million in fresh capital, the bet for Eight Sleep remains that its blend of hardware and software will continue to find a decent resting place, no matter the price.
