The ritual mattered
The product started with an everyday problem, not a gadget brief: people wanted the drink they already loved to stay right.
Ember
Our Story
A better morning ritual, built from a simple idea: your drink should stay exactly how you like it.
Founder note
Welcome to a dream come true
As a lifelong coffee lover and inventor, I always wondered — what if the perfect sip could last forever? I began dreaming of a self-heated coffee mug that could maintain a precise temperature. After several years of prototypes and rigorous engineering, Ember was born—turning my dream of creating the world's first temperature-control mug into a reality for coffee and tea lovers everywhere.

The original Ember story.
Clay shares the early idea, prototypes, and engineering behind the world's first temperature-control mug.
Our story
Built from one simple frustration.
Coffee and tea start perfect, then drift. Ember began with the belief that the best part of the cup should last longer.
The tech became invisible
Temperature control only works if the product still feels like a mug, cup, or tumbler first.
The category grew
What began with hot coffee now spans cups, tumblers, cold drinks, gifts, and coffee subscriptions built around the same ritual.
Morning
Built for daily use
Gifts
Made to be kept
Ritual
Not novelty
