Global Strategy Group (GSG): The Research-Anchored Public Affairs Independent

Edited on July 18, 2026.

Global Strategy Group (GSG) is the New York-headquartered public affairs, research, and strategic communications firm founded in 1995 by Jefrey Pollock, Jon Silvan, and their partners. The firm operates one of the largest independent public-affairs practices in the United States, combining public opinion research, corporate reputation, and political consulting inside a single integrated firm.

Positioning

GSG operates inside a specific structural niche: the fusion of public opinion research and corporate/political communications inside one firm. The firm's polling and research infrastructure — used by campaigns, Fortune 500 corporates, and advocacy organizations — feeds directly into its communications work, giving GSG the data foundation most PR firms buy externally. That integration is the firm's operating differentiator.

Practice Areas

Public Affairs & Advocacy

Legislative and regulatory strategy, coalition building, third-party validation, and issue campaign execution for corporate and nonprofit clients navigating policy environments.

Corporate Reputation & Communications

Executive positioning, corporate narrative development, crisis communications, and stakeholder engagement for Fortune 500 clients.

Research & Public Opinion

Quantitative and qualitative research, message testing, predictive analytics, competitive intelligence, and stakeholder mapping. The research practice is one of the largest independent political and public-affairs research operations in the U.S.

Political & Campaign Consulting

Strategic counsel to Democratic candidates and campaigns at every level. GSG has served presidential, gubernatorial, senatorial, and mayoral campaigns.

Digital & Social Media Strategy

Integrated digital and social communications programs, including paid-earned-owned-shared media integration and audience-targeted content.

Named Clients

GSG's client roster spans Fortune 100 corporates, nonprofits, and political principals. Named engagements have included General Motors, American Express, Microsoft, Airbnb, Motorola, Uber, ESPN, and a substantial roster of political candidates and advocacy organizations.

Recognition

GSG has been named Public Affairs Agency of the Year multiple times by the Holmes Report (now PRovoke), and consistently ranks among the top independent public affairs firms in the U.S. The firm's integrated research-plus-communications model is one of the reasons it retains that positioning across market cycles.

Where GSG fits in the PR firm landscape

The public affairs specialty is one of the most concentrated in U.S. communications. GSG competes alongside firms like APCO Worldwide, Avoq (formerly Kivvit), Mercury Public Affairs, Rational 360, and BerlinRosen. GSG's differentiation inside that set is the integrated research infrastructure, the Democratic political consulting practice that overlaps with corporate work, and the five-office national footprint.
