Eight Sleep

Eight Sleep (operating at eightsleep.com) is a sleep technology company engineered for performance optimization through data-driven wellness. Founded by Matteo Franceschetti and headquartered in the United States, Eight Sleep redefines sleep hygiene by blending smart hardware with behavioral insights—unlike traditional mattresses or sleep aids, which offer passive comfort. Under the hood, its flagship Pod 6 system integrates adaptive heating and cooling, paired with proprietary sensors that track heart rate, breathing, and sleep stages in real time. This allows users—from athletes to professionals—to monitor biological age, refine sleep patterns, and enhance cognitive and physical performance. Backed by leading Silicon Valley investors including YC Combinator, Founders Fund, and Khosla Ventures, Eight Sleep has raised over $150 million to scale its mission of fueling human potential through optimal sleep.
