Our Story

Our Founder, Eliza Twist, came up with the idea whilst working at an investment bank in London — waking at 5am, answering client calls late into the night, and constantly tethered to her phone. To protect her sleep and mental health, she made a bold decision: to leave her phone outside the bedroom for good.

Having slept with an iPhone since the age of 11, this small act transformed her nights and her wellbeing. She encouraged her mum and close friends to try the same. The results were immediate: better sleep, clearer minds, and calmer mornings.

But after a break-in at Eliza’s apartment, everything changed. Her mother, though now a firm believer in switching off, refused to be unreachable at night ever again. Eliza searched for a device that could allow people to disconnect while still remaining contactable in an emergency — but it didn’t exist.

So she built it.

FOUNDER & CEO

Eliza Twist

With a background in property and investment banking, Eliza Twist experienced first-hand the toll of burnout and insomnia — sparking the idea for Zebble. Since founding Detach Tech, Eliza has led Zebble from concept to launch: securing patents and IP, winning over investors, clinicians, politicians, and athletes, and securing partnerships with leading luxury wellness hotels, corporates, and elite sports professionals.
In recognition of her work, Eliza was awarded Barclays Entrepreneur of the Year 2025. Alongside her role as CEO, she sits on the board of a leading UK construction firm and serves on Google’s Female Advisory Council. She is also a passionate advocate for women in entrepreneurship and mentors several female founders through their early-stage journeys.
