News of the Day

Eight Sleep has secured $50 million in a strategic funding round led by Tether Investments, propelling the sleep tech innovator to a $1.5 billion valuation as it pivots toward clinical healthcare. Having achieved free-cash-flow positivity in 2025, the company is now seeking FDA approval for technology capable of detecting and mitigating sleep apnea, signaling an ambitious move beyond its origins in consumer mattress accessories. CEO Matteo Franceschetti revealed plans for a proactive AI "sleep agent" that simulates environmental scenarios to adjust bed temperature, firmness, and elevation before a user even lies down, leveraging proprietary data that has already shown success in nudging users to improve daily habits. This expansion follows a rocky 2025 marked by an AWS outage that caused products to overheat, leading to the implementation of a new "outage mode" as the firm continues to compete against heavyweights like Oura and Whoop in the increasingly crowded global health-tracking ecosystem.
