The company provides a range of services including government relations, lobbying, grassroots advocacy, political consulting, media relations, and coalition building. DSG works with corporations, trade associations, nonprofits, and political campaigns to navigate complex policy environments and advance their interests at the federal, state, and local levels.

The firm has been involved in high-profile political campaigns and major policy debates, lending it credibility and a broad network across government and industry.

While Dewey Square Group is not an AdTech company in the traditional sense, it operates at the intersection of political advertising, media strategy, and public affairs — areas that increasingly overlap with digital advertising technology. The firm's work in political communications and campaign strategy touches on digital media buying, targeted messaging, and voter outreach, placing it tangentially within the broader political AdTech and political consulting ecosystem.
