Public relations has always been about three things: influence, reputation and authority. But in 2025, influence looks different. It’s no longer just about securing the Wall Street Journal or a glossy feature—it’s about whether your brand shows up in AI answers.

Generative search has rewritten the rules of visibility. Today, the most powerful drivers of brand presence is a mix of earned media, like trade publications, coverage by analyst firms and those viewed as “trustworthy” voices, and validation from credible reviews and sites like Reddit now carry more weight than ever. These signals shape not only what people read, but also what machines surface as the authoritative answer.

That’s why agencies leading the next wave of PR are those who don’t just pitch stories, they engineer visibility across both human and machine audiences. They are adopting AI-powered monitoring, building generative search strategies, and ensuring that their clients’ voices are consistently reinforced across the outlets and communities AI engines trust most.

Below is a look at the Top B2B PR Agencies Using Generative AI Tools in 2025, a mix of global giants and nimble boutiques who are setting the standard for influence in the AI age.
