Eight Sleep, a startup that sells mattresses powered at $ 3,000 with sub-be-month fees, has just collected $ 100 million in series D series, in the hope of strengthening a relatively new idea with a discretionary consumption sector.
La Ronde – Directed by Founders Fund, Y Combinator, Valor Equity Partners, and HSG (formerly Sequoia China) – Malues ​​fired investments by the F1 pilot Charles Leclerc and the CEO of McLaren Racing Zak Brown.
The agreement pushes the company’s rating to around $ 500 million, with more than $ 500 million in pods sales declared since the launch.
Eight people ‘pod system uses tubes filled with water in a mattress cover to adjust the bed tempter between 55 ° F and 110 ° F (13-43 ° C).
Integrated sensors follow the heart rate, breathing, the variability of the heart rate, which an AI system called Autopilot used to modify the environment in real time.
Prices start at $ 2,500 for the mattress at the top and climb more than $ 4,000 for the While system. THR’s has $ 17 at $ 25 Subfix
The company has raised a high -level fans base, including Elon Musk and Mark Zuckerberg. Scarlett Johansson jurors, and Biohacker Bryan Johnson, who spends $ 2 million a year in anti-aging, is another user.
“It’s fun for sleep optimization, expanding insos medical applications such as menopausic sleep and sleep apnea and bring our technology to millions of people attend the world,” said CEO Matteo Francesttti in the announcement. The former lawyer, who became Sleep Ohived, founded the company in 2014 after marked his own sleep problems.
But not all comments are positive. On social networks, users have shared stories about seeds that make the system stop working entirely, leaving them with an attentive and non -functional bed. Others have reported problems with water leaks and connectivity problems.
I woke up because my bed controlled by AI is too cold. I went to adjust the storm and I cannot decided that the application of eight people is currently broken. I cannot adapt to the hand because I have a pod3, not the improved pod4 with physical commands.
Now I’m stuck in a cold bed. It seems dystopian.

The system of the system has been called a “black box” by some users, who complain that it does not provide transparent data.
The new financing of eight Sleep will support the development of what he calls a “sleep agent”, the AI ​​that will perform thousands of night simulations to further refine the rest of a user. The Company also finds the approval of the FDA for medical applications of its technology, including the treatment of menopausic heat puffs and sleep apnea.
The company claims that its AI models have processed more than a billion hours of sleep data. With 100 million dollars in fresh capital, the bet for eight sleep remains that its blind hardware and software will continue to find a decent rest place, whatever the price.
