GSD&M

A creatively-led, purpose-driven full-service agency within the Omnicom network, known for long-term national brand partnerships and culturally resonant campaigns.

GSD&M is a full-service advertising and marketing agency headquartered in Austin, Texas, founded in 1971 by Roy Spence, Judy Trabulsi, Steve Gurasich, Tim McClure, and others. The agency is known for its 'Purpose-Based Branding' philosophy, which centers on helping brands identify and articulate a deeper purpose that drives their marketing strategy. Over its history, GSD&M has built long-standing relationships with major clients including Southwest Airlines, USAA, PGA Tour, and the U.S. Air Force, among others. GSD&M operates as a subsidiary of Omnicom Group, one of the world's largest advertising holding companies, which acquired the agency in 1998. Despite its corporate parentage, GSD&M has maintained a distinct identity and culture rooted in Austin's creative community. The agency offers a full suite of services including brand strategy, creative development, media planning and buying, digital marketing, social media, and integrated campaign management. In the broader AdTech and advertising ecosystem, GSD&M occupies a position as a creatively-led, strategically-driven agency rather than a pure technology platform. Its competitive differentiation lies in its purpose-driven methodology, deep client relationships, and a track record of culturally resonant campaigns. The agency competes with other mid-to-large independent and holding-company-owned agencies for national brand accounts, particularly those seeking a values-aligned creative partner.
