Eight Sleep Raises $100 Million to Build the OS for Sleep

For a third of American adults, poor sleep has become a routine condition rather than an exception. New York–based Eight Sleep, which calls itself the world’s first “sleep fitness company,” is betting that the bed itself can become the center of health monitoring and intervention.

The company, founded in 2014, announced this week that it has secured a fresh $100 million round of funding. The raise was backed by HSG, Valor Equity Partners, Founders Fund, Y Combinator, and high-profile names from the world of motorsport, including Ferrari F1 driver Charles Leclerc and McLaren Racing CEO Zak Brown. With the latest investment, Eight Sleep’s total funding climbs to roughly $260 million, according to PitchBook. The company previously closed an $86 million Series C in 2021 at a $500 million post-money valuation. Eight Sleep says its valuation has since doubled, though it declined to provide specifics.

Eight Sleep’s flagship product, the Pod, integrates AI, sensors, and thermal regulation into a sleep surface that can dynamically adjust temperature, firmness, and elevation. The system tracks metrics such as heart rate, breathing patterns, sleep stages, and movement, then makes real-time adjustments including automatically elevating the head to reduce snoring.

That combination has resonated with consumers. Eight Sleep reports more than $500 million in Pod sales and a tenfold revenue increase since the product launched in 2019. The company has also amassed a database of over one billion hours of recorded sleep, which underpins its AI models.
