About

One of the top-ranked global PR agencies by revenue and reputation, operating within Omnicom Public Relations Group with a presence in 80+ markets worldwide.

FleishmanHillard is a public relations and marketing agency founded and based in St. Louis, Missouri. Its communications work increasingly intersects with the advertising and marketing technology space, as the agency positions its teams to shape brand visibility and optimize content for the AI-driven systems that influence how brands are perceived and discovered. The agency offers a Brand Impact practice, led by a dedicated global head, that spans brand strategy across B2B, B2C, and B2G audiences and draws on data, intelligence, and industry insights to drive measurable business outcomes. Its Canadian operations, recently rebranded and realigned under a renewed global strategy, emphasize data-driven insights, AI, and a proprietary virtual audience platform called Sage to help clients communicate and compete in complex, multi-stakeholder environments. Acquired by Omnicom Group in 1997, the agency operates across 78 offices in 30 countries spanning the Americas, Asia Pacific, Europe, the Middle East, and Africa.
