MNTN

Mntn, Inc.

An advertising software company, MNTN runs a self-serve platform that lets brands buy and track commercials on connected TV and streaming services the same way they manage search and social ads. Founded in 2009 as SteelHouse, it renamed itself MNTN (pronounced "mountain") in 2021 to signal peak performance in TV advertising. In a fun twist, actor Ryan Reynolds' marketing agency Maximum Effort joined the company that year, with Reynolds serving as its chief creative officer.
