My guest today is Matteo Franceschetti, the founder and CEO of Eight Sleep, a smart mattress company. I’m a customer of Eight Sleep and this was one of the most unique founder conversations I’ve had on the show, in both the focus on the product and the exploration of sleep. We talk about which biometrics matter, how hard it is to start a hardware company and launch manufacturing overseas, how Matteo manages his own sleep, and the massive potential for preventative health companies like Eight Sleep may have in the future. I hope you enjoy this conversation with Matteo Franceschetti.    For the full show notes, transcript, and links to mentioned content, check out the episode page here. ----- Founder's Field Guide is a property of Colossus Inc.
