Whilst struggling with burnout and insomnia working at a leading Investment Bank in London, CEO and Founder Bradfieldian Eliza Twist (M 11-16) came up with the solution to switching off with peace of mind in order to prioritise sleep, health and well-being.

Zebble is a wellness technology company redefining how we sleep, switch off and reconnect.

At its core is a beautifully designed bedside device, a small marble textured pebble that allows users to remove their phones from the bedroom without losing peace of mind. By enabling selected emergency contacts to reach you when it truly matters, Zebble removes the anxiety of being unreachable while eliminating the distractions, blue light and dependency that come with keeping a phone by the bed.

Zebble functions as both an alarm and a safety net, revealing the time only when needed and allowing users to listen to curated audio for a seamless, screen free wind down experience.

Alongside the device, Zebble+ offers a premium subscription platform featuring content created and curated by the world’s top sleep doctors, supporting better sleep, mental clarity and overall wellbeing.

Founded by Eliza Twist, following her own experience with burnout and always on culture, Zebble is built on a simple belief, the bedroom should be a place for rest, not notifications.

Already working with leading hotel groups, global corporates such as Barclays and PwC and elite athletes, Zebble is positioning itself at the forefront of the global sleep and digital wellbeing movement.

Available to everyone; adults, students, corporations and individuals worldwide. Find out more here
