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

Tech-news ,

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.

The humble cockroach: depending on where you live, they’re variously the bane of apartment dwellers, a tasty snacc, or a source of political inspiration. The cliché is that they’d be the only creatures to survive a nuclear apocalypse, and whether or not that’s true, you probably wouldn’t put them first in line for further enhancements to their already legendary ability to survive.

However, it seems that no one’s told that to the folks at Nanyang Technological University in Singapore, because a group of researchers from the university’s School of Mechanical and Aerospace Engineering recently published a paper describing the process of fitting a cockroach with a diving suit. As the paper’s abstract explains, “The suit integrates a miniaturized oxygen generation module with a flexible waterproof shell, enabling continuous oxygen supply and isolation from surrounding water.”

Or, in other words, the suit successfully allowed the insect to breathe underwater, turning it into a sort of nightmarish amphibious cyborg. If this sounds like a terrible idea at face value, console yourself with the knowledge that these cyber-roaches are designed to be used for benevolent purposes. As per the paper, said purposes include pipe inspections, “object transportation,” and, apparently, search-and-rescue missions. (Smash cut to 2031 and Elon Musk ranting about a “pedo roach”.)

Research into the creation of cyborg insects has been a thing for some time, both in academia and in the world of tech. On the latter point, readers may remember the RoboRoach, a $200 DIY kit for creating your own cyborg cockroach that was funded via Kickstarter in 2013. The kit is still available, and these days it seems to be marketed as a fun activity for kids—on the manufacturer’s website, it’s labelled as being for “Grade 9+” and “[Requiring] supervision.” If the idea of a bunch of 15-year-olds performing surgery on cockroaches makes you kinda queasy—supervision or not—well, you’re not alone.

Let’s get back to the Nanyang Technological University, where the experiments are presumably not being conducted by middle-schoolers. If you’ve ever wondered how a cockroach breathes, the paper explains that “like most terrestrial insects, [they] breathe through thoracic spiracles that take in oxygen directly from the air.” The “diving suit” is basically a flexible waterproof shell into which a miniature oxygen generator pumps oxygen, effectively creating a tiny breathing bubble around the insect’s air-intake thingamajigs.

This allowed the insect to breathe underwater for up to three hours, although it seems there were some initial, um, design issues to sort out: “Dorsal mounting of the oxygen generator on the cockroach created significant water-resistance during underwater locomotion… causing postural instability and rollover.” Once this issue was resolved, it seems the roaches got on just fine underwater, exhibiting “stable and smooth underwater walking without rollover.” The researchers conclude that the idea is a winner, and that it could be “potentially extended to other terrestrial cyborg insect platforms, such as [other] cockroaches, locusts and beetles.” Amphibious locusts! What could possibly go wrong?

During this year’s World Cup, one scene repeats itself game after game: Several players take the field with holes in the calves of their socks. Social media is rife with theories about the supposed competitive advantage this might give them. But the practice isn’t new. It has been seen at the European Championships, the Olympic Games, and other international competitions over the past decade. Still, science has yet to find evidence that it improves performance.

Professional soccer socks are, by design, form-fitting. In addition to holding shin guards in place, they provide support to the ankle, the arch of the foot, and the calf; they help manage moisture and reduce foot movement inside the cleat to improve stability. This design principle has been used in professional soccer for decades. Although materials have evolved to become lighter and more durable, they are still primarily based on synthetic fibers such as polyester, nylon, and spandex.

But quite a few players have complained that the socks are too tight and cause a tingling and numb sensation in the calf area. The discomfort is so great that, halfway through a game, they cut several holes in the calf area to “release tension” and run better.

There is a biomechanical component to this sensation. During a sprint or a change of direction, the largest muscle in the calf contracts and increases in thickness to generate the force that propels the athlete forward. This change in shape occurs thousands of times during a game. For some, the repeated expansion of the muscle is enough to create a sensation of pressure when the sock exerts constant compression on the calf.

Over time, the practice of cutting holes in socks has taken on an almost intuitive explanation among the players themselves: splitting open the fabric allows the muscle to “breathe,” relieving pressure and reducing the likelihood of pain or cramps. However, specialists in sports medicine and recovery point out that there are no studies demonstrating that cutting holes in socks provides any benefit. In fact, much of the research on compression garments concludes that, when properly designed and fitted, they can help limit muscle inflammation after intense exertion.

Despite the lack of evidence regarding physiological benefits, the practice continues to spread among professional soccer players. Today, it is considered primarily an anecdotal phenomenon, based on each player’s personal experience rather than scientific evidence. Furthermore, the rules of the game do not prohibit modifying socks, as long as the equipment remains safe and the shin guards remain properly covered. (A soccer player, however, cannot play with a torn jersey.)

Given the lack of scientific evidence, several specialists believe that part of the phenomenon could be explained by the player’s own perception of comfort. In high-performance sports, the feeling of comfort can influence the confidence with which an athlete competes. If a soccer player believes a piece of clothing is restrictive, eliminating that perceived discomfort can make them feel freer to run, accelerate, or change direction—even if their performance remains objectively unchanged.

Though there is no evidence that cutting the socks provides a competitive advantage or reduces the risk of injury, that does not mean the sensation of discomfort is imaginary. The perception of pressure, restriction, or comfort depends on multiple factors, ranging from anatomy and individual sensitivity to the athlete’s past experiences. In other words, two players may react differently while wearing exactly the same equipment.

For now, it seems the cutting of socks will continue. The available evidence points to a mechanism similar to that of other sports rituals: Its effect is primarily psychological, not necessarily physiological.

The best VPNs for streaming are not free, but they do tend to offer money-back guarantees and free trials. By leveraging these offers, you can unblock BBC iPlayer without committing with your cash. This obviously isn’t a long-term solution, but it gives you plenty of time to live stream Wimbledon 2026 before recovering your investment. It’s a sneaky trick, but it works.

ExpressVPN’s regular 30-day money back guarantee is not available for any subscriptions purchased during the FIFA World Cup between June 10 and July 11.
