The funding round was announced Tuesday. It follows another $100 million raise that Eight Sleep completed in August last year. Eight Sleep focuses on sleep health products that include smart bedding systems and related wellness solutions. The company collects and analyzes sleep data through connected devices.

Meanwhile, Tether continues expanding its investment strategy beyond cryptocurrency markets. The firm has directed capital into sectors such as biotechnology, artificial intelligence, gold, and media. It has also explored acquisitions in the professional football sector.

Tether Expands Investment Strategy Beyond Crypto

Tether described the investment as part of a broader strategy targeting health technology development. The company views health data analysis as an important tool for improving wellness and disease prevention. Consequently, the investment supports the development of AI-driven health technology.

Moreover, the partnership aims to combine Tether’s technology architecture with Eight Sleep’s existing products. The collaboration will integrate Tether’s QVAC system into the company’s sleep monitoring ecosystem. This infrastructure focuses on secure data processing and privacy.

QVAC launched in December as a privacy-focused health technology platform. It allows users to combine biological health data from several devices into one system. For example, users can connect smart rings and other health trackers.

Additionally, the platform processes data locally using on-device artificial intelligence. This structure helps users manage personal health data and receive insights while maintaining privacy.

AI Integration Targets Next Generation Sleep Technology

Eight Sleep plans to use the funding to expand its artificial intelligence capabilities. The company will develop a sleep-focused AI agent to enhance its Pod product. The Pod is a smart sleep system that adjusts bed temperature, elevation, and sound automatically.

The system analyzes several biological signals during sleep. These include heart rate, breathing patterns, snoring, sleep duration, and sleep stages. Based on this data, the Pod modifies environmental conditions throughout the night.

Furthermore, the company intends to improve its existing AI tools. The current platform already collects and processes sleep health data through integrated sensors. However, the new funding will accelerate development of more advanced capabilities.

Eight Sleep also plans to build predictive technology using large datasets. The system will rely on more than one billion hours of sleep data collected through its platform. In addition, the company continues work on regulatory filings related to sleep apnea detection.

The new technology focuses on passive health monitoring. The system operates automatically during sleep and does not require clinical equipment or complex setups.

The partnership allows Eight Sleep to combine its sleep data platform with Tether’s artificial intelligence infrastructure. Consequently, the companies aim to extend AI-powered health monitoring beyond sleep products into broader personal health applications.
