Summary
- Eight Sleep secured $50 million, reaching a $1.5 billion valuation.
- The company plans to use funding for new products and global expansion.
- Eight Sleep seeks FDA approval for sleep apnea detection products.
Eight Sleep, a pioneer in sleep technology, has successfully raised $50 million in a funding round led by Tether Investments. This strategic investment propels the company's valuation to $1.5 billion, following a previous $100 million round in August 2025.
The company, known for its smart mattress accessories that monitor sleep and regulate temperature, reported being free-cash-flow positive in 2025. The newly acquired capital is earmarked for advancing product lines, facilitating international market entry, and pursuing clinical validation for its technologies.
Eight Sleep is expanding its focus beyond consumer products, actively seeking FDA approval for devices designed to detect and mitigate sleep apnea. This initiative marks a significant step towards integrating its technology into broader healthcare solutions.
Matteo Franceschetti, CEO of Eight Sleep, stated their ambition to create a defining health technology company, driven by a system that deeply understands and acts on individual body data each night. The company is developing an AI agent to proactively manage sleep environment factors like temperature, elevation, and firmness.
Early trials of Eight Sleep's AI-driven guidance have shown positive results, prompting users to adjust daily habits such as exercise timing, caffeine intake, and sleep schedules based on app analysis. This comes after the company addressed a past controversy involving product functionality during an AWS outage in October 2025, by implementing an "outage mode."
