Eight Sleep Raises $100M for AI-Powered Mattress Amid Mixed Reviews

Eight Sleep, a startup specializing in AI-driven sleep technology, has secured $100 million in Series D funding. The round was led by prominent investors including Founders Fund, Y Combinator, and Valor Equity Partners, with participation from F1 figures Charles Leclerc and Zak Brown. The company's valuation now stands at approximately $500 million, with cumulative sales surpassing the same figure.

The Pod system, Eight Sleep's flagship product, employs water-filled tubes and AI to regulate bed temperature and monitor biometric data. Despite its high-profile endorsements from Elon Musk and Mark Zuckerberg, user complaints about technical issues persist. The product's premium pricing—ranging from $2,500 to $4,000 plus a monthly subscription—positions it as a luxury in the consumer discretionary space.
