Eight Sleep Secures Strategic Investment From Tether to Reach $1.5B Valuation

Eight Sleep announces a strategic funding round led by Tether Investments on March 5, 2026, to transition from sleep optimization to a predictive health platform. The New York-based company currently operates in 34 countries and recently achieved free cash flow positivity while launching three new products.
