Cryptocurrency giant Tether, through its venture arm, has made a $1.5 billion strategic investment in Eight Sleep to accelerate AI-driven healthcare technology, according to an announcement on Wednesday.
The agreement aims to establish a long-term partnership between the two companies, and Eight Sleep plans to incorporate Tether’s QVAC architecture into its products.
QVAC Health is Tether’s recently launched platform to integrate fitness and health data from wearable devices and multiple inputs into a single, encrypted environment that works without relying on third-party cloud services.
Tether CEO Paolo Ardoino said advanced AI can unlock human potential by providing actionable insights into key aspects of health. He noted that Eight Sleep is positioned to advance longevity-focused technology by building adaptive systems and devices that help individuals improve sleep, recovery and overall well-being.
“We believe that advanced personalized AI is the best way to realize and expand human potential,” Arduino said.
“By helping people understand sleep, recovery and long-term health, Eight Sleep sets the stage for a new standard in longevity technology that is truly personalized, can work in any environment, is directly on the device, is sustainable and fits into people’s lifestyles,” he said.
Tether’s backing comes after Eight Sleep secured $100 million in a funding round from investors including HSG, Valor Equity Partners, Founders Fund, Y Combinator and Formula 1 figures Charles Leclerc and Zac Brown.
The New York-based sleep technology startup makes smart mattress systems that use embedded sensors and machine learning to adjust temperature and track physiological data in real time.
The company plans to expand beyond sleep monitoring into broader health applications through partnerships.
“Sleep was just the beginning,” said Matteo Franchetti, co-founder and CEO of Eight Sleep. “This partnership with Tether gives us the infrastructure to bring this intelligence beyond the Pod to all aspects of personal health.”
Tether Investments, headquartered in El Salvador, allocates capital from the stablecoin issuer’s profits in sectors including artificial intelligence, energy, biotechnology and financial services.
