A note from the founder

“Zest was born from our own pursuit of better mornings.”

Read the full letter

Zest was born from our own pursuit of better mornings.

Like many of you, I've felt the frustration of waking up groggy, despite trying every trick and sleep solution out there. As a night owl with a background in sleep research and having worked with top sleep clinicians and physicians at my previous sleep company, Crescent, I knew that the science existed to make mornings better – and wanted to make it easy and accessible to everyone.

From this dream, Zest was born. I set out to create better tools for making better sleep and energy effortless.

Together with leading scientists, physicians, and sleep experts who understand the science of better sleep and health, we developed our flagship “Wake-Up Pill”, which releases caffeine at an optimal time, helping you wake up feeling naturally alert and ready to perform at your best. It's designed to support your long-term sleep health through consistency over time.

Zest is for those who want more out of their days. It's for the late-night creatives, the professionals who don't have time to ramp up slowly, the jet sailers chasing time zones, and the dreamers and doers living life to the fullest.

Thank you for joining us on this journey. Let's do great things together.
