Our take
The last decade has seen a major uptick in the number of start-ups and companies dedicated to supporting consumers to build good health habits, typically around food and fitness. That enthusiasm is now quite rightly being extended to how we sleep.
Eight Sleep makes “smart” mattresses and mattress covers (for regular mattresses) that use machine learning and other artificial intelligence-based algorithms to improve your sleep both by changing temperature and monitoring other physical parameters to provide an overall picture of your health.
The company is focused on two levers for growth; building out more technology through additional products and acquisitions, and expanding internationally. It's seeing great success too, having recently raised $50M, brining its valuation up to $1.5B.
