Stagwell Inc. is a global marketing and communications group founded in 2015 by Mark Penn, initially backed by a $250 million investment from former Microsoft CEO Steve Ballmer. The company operates as a digital-first network that helps clients evolve their creative, media, technology, digital platforms, audiences, and products to build fully integrated marketing strategies. Its Stagwell Media Network brings together a parcel of media agencies — including Media Kitchen, Assembly, and Multiview — accounting for close to $5 billion in media spend. Stagwell has also pursued growth in out-of-home advertising through a strategic partnership with OOH specialist Talon, expanding its collective global presence in data-driven OOH planning, buying, and proprietary technologies for advertisers. On the technology side, Stagwell has acquired an AI-powered SaaS platform and a creative technology partner focused on AI, digital transformation, and immersive experiences. The company is publicly traded on NASDAQ under the ticker STGW, headquartered in New York with significant offices in Washington, DC.
