Funds aim at predictive AI for health prevention, clinical validation including women's sleep research (e.g., 56% reduction in menopausal hot flashes), R&D, global partnerships, and competing with Oura and Whoop by actively adjusting sleep environments. Products are used by athletes like Charles Leclerc and Taylor Fritz. |
| Aug 2021 | Series C | Valor Equity Partners (lead) | $86M | $450M | Eight Sleep is a New York-based sleep technology company founded in 2014 by Matteo Franceschetti and others, specializing in smart mattress covers and accessories like the Pod system that track sleep stages, heart rate, body temperature, and automatically regulate bed temperature for optimal rest.

The Series C funding supported growth, global expansion, and advancements in sleep fitness technology, positioning Eight Sleep in the competitive landscape alongside products like BedJet, Chilipad for temperature control, and Oura, Whoop for sleep tracking. Subsequent rounds included a $100 million Series D in August 2025 led by HSG with Valor Equity Partners and others, and a $50 million strategic round in early 2026 led by Tether Investments reaching a $1.5 billion valuation, with total funding over $310 million.

| Mar 2016 | Seed | Azure Capital Partners; Y Combinator; Comcast Ventures; Stanford University; Vast Ventures; Yunqi Partners; Cota Capital; Upslope Ventures | $6M | - | Eight Sleep raised a $6 million Seed round in 2016 led by a consortium of investors including Y Combinator, with the company at a very early stage of development. At the time of this raise, Eight Sleep had shipped a Sleep Tracker and Smart Bed to customers but had not yet launched its flagship Pod product, which would later become the core of its business. The company's financial performance at this early stage was challenging, with low gross margins and contribution margins as it developed its hardware and data platform. Eight Sleep would go on to raise subsequent funding rounds, including a $12.9 million Series A also in 2016, as it continued to scale toward becoming a profitable, growth-stage company. |
