PANews reported on March 4th that, according to CoinDesk, USDT issuer Tether has invested $50 million in sleep technology startup Eight Sleep, valuing the company at approximately $1.5 billion. Eight Sleep will develop new AI health features based on Tether's QVAC architecture, enabling more data processing on the end-device side and reducing reliance on the cloud . Eight Sleep primarily manufactures sleep systems with built-in sensors; its Pod products can monitor physiological indicators such as heart rate and body temperature, automatically adjusting mattress temperature and generating sleep analysis. This investment continues Tether's strategy of investing over $10 billion of its annual profits in energy, payments, artificial intelligence, and health technology, and synergizes with its recently launched health data aggregation platform, QVAC Health.
