Eight Sleep Raises $50 Million At $1.5 Billion Valuation

Securing Strategic Capital

Eight Sleep has raised $50 million in a new funding round led by Tether Investments, valuing the sleep technology company at $1.5 billion. The funding follows a $100 million round completed in August that included investors such as HSG, Valor Equity Partners, Founders Fund, and Y Combinator. Earlier financing valued the company at $500 million after an $86 million Series C round in 2021 led by Valor Equity Partners.

Innovative Product Expansion And Global Reach

The company is renowned for its smart mattress accessories designed to track sleep patterns and adjust temperatures in real time. With more than $310 million raised to date, Eight Sleep has achieved free-cash-flow positivity in 2025, and its products are now shipped to over 34 countries. The new capital is earmarked for the development of new products, further global expansion, and clinical validation, reinforcing its market-leading position in sleep technology and health innovation.

A Visionary Approach To Sleep Health

Eight Sleep is also expanding into medical applications of sleep technology. The company is pursuing approval from the U.S. Food and Drug Administration for devices designed to detect and help manage sleep apnea. Chief executive and co-founder Matteo Franceschetti said the company is developing systems designed to analyze sleep patterns and respond to physiological signals throughout the night.

AI-Driven Sleep Optimization

A key element of Eight Sleep’s strategy is the development of a sleep-focused AI agent. This innovative system proactively manages product parameters such as temperature, elevation, and firmness to optimize sleep conditions. Early pilots have shown that the AI-driven insights prompt users to modify habits, including exercise timing, caffeine intake, and sleep schedules, thereby fostering healthier routines.

Expanding Product Portfolio Amid Market Challenges

The company recently introduced additional products, including a hydro blanket and a temperature-regulated pillow cover. Operations were briefly affected in October when an outage involving Amazon Web Services disrupted connectivity for some mattress devices, triggering an “outage mode” designed to prevent overheating. Eight Sleep operates in a competitive market that includes companies such as BedJet, ChiliSleep, Oura Health, and WHOOP, which also develop sleep and health monitoring technologies.

Looking Ahead

The company said the new funding will support product development, expansion into additional markets, and continued clinical research. The investment highlights growing investor interest in technologies focused on sleep monitoring and health optimization.

China’s Humanoid Robot Boom Faces A Bigger Question: Can These Machines Make Money?

Unitree’s $9 Billion Bet On The Future Of Robotics

China’s humanoid robotics industry is attracting huge investor interest, but as Unitree Robotics prepares for its public debut, questions are growing over whether its robots can move beyond impressive acrobatics and become commercially viable tools.

The Hangzhou-based startup priced its IPO at 150.8 yuan ($22.4) per share, raising $900 million and valuing the company at 61 billion yuan, or about $9 billion. The offering attracted record retail demand on Shanghai’s STAR Market, with the online tranche oversubscribed more than 5,000 times and a winning rate of just 0.018%. Strategic investors included AI startup DeepSeek.

A Unitree-linked pre-IPO perpetual contract was trading at roughly four times the IPO price on Friday, highlighting the speculative interest surrounding the company.

Unitree is known for robots capable of kung fu kicks, backflips and recovering from falls. Yet analysts question whether the technology is ready for large-scale commercial use. “For these humanoid robots, to be honest, they’re fascinating. They can dance and all that, but I’ve never seen them doing any real housework,” said Hao Hong, managing partner of Lotus Asset Management.

In its prospectus, Unitree warned that mass adoption could take longer than expected because robotic hands are still not precise or durable enough for sustained use.

From Acrobatic Robots To Commercial Machines

Even advanced humanoid robots can currently perform only a limited number of tasks and typically operate for a few hours before recharging, according to Dominik Pross, an equity analyst at VP Bank. Most models run for up to four hours, while robots also need to be trained for individual tasks.

“Robots have to be specifically trained for each and every task entrusted to them, even the simplest,” Pross said.

More robotics listings are expected, with Unitree rivals AgiBot and Leju Robotics seeking listings in Hong Kong and Shenzhen. LimX Dynamics founder Will Zhang said last month that “listing is a must.”

China’s Cost Advantage

China’s manufacturing scale has helped it establish a leading position in robotics. Wood Mackenzie expects the global humanoid robot fleet to surpass 10 million units by 2035, while China already accounts for more than 70% of global industrial robot installations and nearly 90% of humanoids deployed last year.

Average humanoid robot prices fell 93% between 2020 and 2025 to $58,000. Unitree’s flagship G1 costs $16,000, while SemiAnalysis estimates that the company has cut the price of its G1 EDU model by more than 45% to $27,300, while maintaining a 67% gross margin.

Falling prices and government support are attracting investment, but analysts say it will take time to prove that humanoid robots can generate strong returns. Unitree’s revenue more than quadrupled last year, although adjusted first-quarter profit fell more than 52% as research and development and marketing spending increased. Nearly three-quarters of its humanoid revenue in the first nine months of 2025 came from research and education, highlighting the gap between demonstrations and widespread commercial use.

“Unlike many early-stage robotics companies, the Unitree story is backed by real revenue growth,” said Jeff Ko, chief analyst at CoinEx. Still, he noted that its $9 billion valuation, at more than 200 times last year’s earnings, reflects significant speculative interest.

Geopolitical Risks

Unitree’s IPO momentum has continued despite growing pressure on Chinese robotics companies. The U.S. moved last month to ban imports of foreign-made humanoid and four-legged robots, potentially exposing Unitree, which generated about 13% of its revenue from the U.S. last year.

Access to Nvidia hardware and software is another risk, as Chinese robotics companies rely on the technology to power their systems. “Chinese robot producers are not yet in a position to do without Western components completely,” Pross said.

China’s control over rare earths used in robot actuators and motors could nevertheless give its manufacturers an advantage, according to Bernstein analyst Dien Wang.

The Bigger Robotics Opportunity

The potential market is attracting major players, including Tesla, whose CEO Elon Musk is expanding production plans for Optimus humanoid robots. At the same time, some researchers argue that the future of robotics will not be limited to humanoids: quadruped and purpose-built robots can be cheaper and more reliable for repetitive industrial tasks, while humanoids may be better suited to unpredictable environments.

For Unitree, the challenge is no longer proving that its robots can perform impressive tricks. It is proving that they can do enough useful work to justify a $9 billion valuation.
