Tether announced on Tuesday that it led a $50 million strategic investment round in sleep technology startup Eight Sleep, which focuses on smart bedding and wellness products and has a valuation of $1.5 billion. Eight Sleep had previously completed a $100 million funding round last August.
Tether stated that it has a "strong belief" in the health technology sector, believing that technologies supporting "longevity, performance optimization, and disease prevention" will be the next major market. The two companies will collaborate to develop AI-based health technology products, with the core technology based on Tether's QVAC privacy health platform launched last December—an architecture that allows users to integrate biometric health data from wearable devices such as smart rings into a single platform, providing health insights via local AI without data going to the cloud.
AI agent trained on 1 billion hours of sleep data
Eight Sleep's flagship product, the Pod, is a smart sleep system that automatically adjusts bed temperature, tilt angle, and ambient noise based on metrics such as heart rate, breathing, snoring, sleep onset time, and sleep stage. While the product already features AI integration, Eight Sleep founder Matteo Franceschetti stated on X that the funding will be used to build a completely new predictive AI agent, trained on over 1 billion hours of sleep data.
Franceschetti also revealed that the company is pursuing an FDA application for a sleep apnea detection system that is "passive, operates automatically every night, and requires no wires or clinic visits." He emphasized that the goal of this collaboration is to extend AI health intelligence "from the Pod to every aspect of personal health."
Tether's non-crypto empire continues to expand.
This investment is the latest move by Tether to actively expand beyond cryptocurrencies. Leveraging the substantial capital generated by its USDT stablecoin business, Tether's investment portfolio in recent years has spanned the gold industry, media, biotechnology, and AI, and has even made several attempts to acquire professional football clubs.
For the crypto industry, Tether's strategic shift is noteworthy. On one hand, USDT's market position as the world's largest stablecoin provides it with a continuous stream of cash flow; on the other hand, investing profits in high-growth sectors such as AI and health technology signifies that Tether is building a diversified technology conglomerate that extends far beyond stablecoins. Whether this model will become a template for other crypto-native companies remains to be seen.
