What Ember Technologies does

Ember Technologies, Inc. is a privately held Delaware corporation founded in 2012 by Clay Alexander and headquartered in Westlake Village, California. The company designs and sells connected temperature-control drinkware, including the flagship Ember Mug 2 (10oz and 14oz), the handle-free Ember Cup (6oz and 14oz), the Ember Tumbler, the recently launched Ember Cold Tumbler in double-wall borosilicate glass, and an Ember Baby Bottle System. Core technology is electro-thermal: precision sensors embedded in the mug wall, paired with a Bluetooth-connected mobile app, hold beverage temperature to ±0.5°F across a 120–145°F range, with battery life of 80–170 minutes depending on form factor. The technology is protected by 31 granted patents and the registered "Temperature Control Mug®" trademark, and is integrated with Apple Health, Apple Siri, and Google Assistant.

Ember monetizes primarily through one-time hardware sales priced $39.95–$179.95 across DTC (ember.com), Amazon, Target retail, and a corporate/wholesale gifting program with 24+ unit minimums and engraving or color-print customization. A secondary recurring layer is the Coffee Club subscription at $25/month or $300/year, which bundles a free 10oz Mug for annual members and ships curated roasts from partners including Onyx Coffee Lab and Purity Coffee. Distribution also includes digital gift cards ($50–$500) and an Ember Brews coffee and tea marketplace, signaling a deliberate shift toward a hardware-plus-consumables model. Customer segments are predominantly individual consumers and, to a lesser extent, corporate gifting buyers; no enterprise anchor customers or revenue concentration are disclosed.

The company has raised approximately $67 million across at least eight equity rounds since 2014, with the largest disclosed financings being a $23.5 million Series E in December 2021 led by GOLDTek Technology (a Foxconn subsidiary) and EDBI, followed by a roughly $21 million Form D exempt offering completed in November 2023. Capital from the Series E is allocated to new product categories, cold chain technology for healthcare, international expansion, and a planned regional headquarters in Singapore. Ember employs 51–100 people and has received recognition including TIME Best Inventions (2017), GQ Tech Awards (2025), Serious Eats Gear Awards (2025), Good Housekeeping Kitchen Gear & Coffee Awards (2022), Men's Health Kitchen Awards (2021), and People Magazine Products Worth the Hype (2020). Revenue, headcount growth, and valuation are not publicly disclosed.
