Smashburger and Mono have teamed up to fulfill the creative needs of the national burger chain.
Minneapolis-based Mono has done work with Sperry, Target and Apple.
"We love the ambition we see in everyone we have met at Smashburger,” said Joe King, Mono’s group director for the account told The Drum. “They are clearly on a mission to grow the brand and we're excited to help them do that. We love their openness to think differently and desire to be inventive in how they make new fans of Smashburger."
The hamburger chain has seen about 25 per cent annual growth and seems keen to expand its marketing as well.
The Drum has reached out to Smashburger for comment, but has yet to receive a response.
