This start-up promises to give coffee lovers their caffeine fix … on their wrists.
Joule (which since our interview has been renamed Perk) claims to be the world's first caffeinated bracelet — giving users a boost of energy through their skin over a four-hour period.
"[Because of its] slow release, the Joule doesn't cause jitters and crashes," co-founder Alex Kryuk told CNBC.
The energy bracelet is made up of a hard silicone material, similar to a FitBit, and uses an adhesive transdermal caffeine patch that sticks to the bracelet and delivers caffeine through your skin when you wear it.
The starter kit (bracelet and 30 patches) retails for $29.99 on the company's website.
Kryuk says the target customer is someone who really likes coffee and is looking for a boost throughout the day but does not have the time to buy another cup of coffee or energy drink.
The company hasn't conducted any studies on the effectiveness of the product and told CNBC "since this is not a medical drug, we are not planning to do clinical trials for the product."
