Eight Sleep's flagship product is the Pod mattress, an intelligent cooling and heating system for your bed. Eight Sleep's technical program manager, Harry Xiao, gets a lot of personal gratification from allowing people to achieve a great nights sleep. “What we do at Eight Sleep…there is this really key sensing technology, but on the other hand, we can do something about it through an actuation mechanism. And that way we can collect the data and then use our technologies to then change something, which is the temperature in which you sleep. And ultimately that feedback loop means the outcome is no longer just a piece of data from a sensor, but it's the feeling that you feel so much more refreshed or it's like "hey, I feel great because I've had good sleep" or "hey, I feel so much better about my day because I have good sleep". And to me, that outcome is just so much more impactful and so much more meaningful than just a bunch of numbers on a page.”
