Tim Antos left banking 6 years ago to found Kokoon (https://uk.kokoon.io/), aiming to help people get better sleep, a problem he himself had solved by going to a sleep clinic, which was time consuming and expensive. Developed over the last 6 years, these headphones are comfortable to sleep in and pack lots of tech, including sleep coaching, tracking, the ability to fade out of whatever you are listening to when you fall asleep and more besides.
Sleep has become big business, and now more than ever people are struggling to get enough good quality sleep. These guys have come up with a really interesting, innovative formula.
