Proof Advertising has been named creative AOR for FiiZ Drinks, a fast-growing specialty soda-shop franchise.

The account was awarded without a competitive review.

Proof will develop brand strategy and creative campaigns to build national visibility for the brand’s “Your Drink. Your Way.” positioning across digital, social and experiential channels. First work is expected to launch later this year.

FiiZ's goal is to expand from 70 locations nationwide to more than 500 across the U.S. and 100 in Canada over the next decade.New market expansion includes Connecticut, Texas and Arizona.

Founded in Bountiful, Utah, in 2014, FiiZ is often called “dirty soda” as it gained traction thanks to Hulu’s “The Secret Lives of Mormon Wives.” FiiZ prefers the term “specialty sodas,” offering 10,000 customizable drink combinations, including flavored sodas, energy drinks, waters and hot beverages, alongside snacks and sweet treats. 

“The specialty soda category is exploding, and FiiZ is right at the center of it with a brand that people genuinely love,” said Bryan Christian, CEO of Proof Advertising. “Our job is to introduce FiiZ to the millions of people who haven’t discovered it yet.”

“As we expand nationally, we needed a partner that knows how to build brands, not just run ads,” said Kelly O’Rourke, director of marketing for FiiZ Drinks. “Proof immediately understood that our growth is powered by community and by the kind of genuine customer love you can’t manufacture.”

Proof is based in Austin, Texas. Clients include Subway Restaurants, Travel Texas, Champion Energy and Hangry Joe’s Hot Chicken & Wings.
