What it is
The Pod is a cover that fits over the mattress you already have, like a fitted sheet. A hub next to the bed moves water through the cover to cool or warm it, and each side of the bed can run its own temperature.
Sensors in the cover track your sleep, so there is nothing to wear. The app shows a morning report, and the alarm can wake you with vibration and temperature instead of sound. Some features, including automatic temperature adjustment, need an Eight Sleep membership.
Why founders should care
Most of what founders buy promises more hours. Sleep is the one input that makes every other hour better. A bad night shows up the next day as a slower decision, a shorter fuse in a hard meeting and an afternoon lost to coffee.
So we are testing the Pod the way we would test any tool for the company: does it change the output, and is it worth what it costs?
