A PR agency switch is a strategic reset, not a handoff, giving B2B tech leaders a chance to realign positioning, messaging, and expectations around growth and credibility. Most fail by carrying forward legacy positioning, vague goals, and volume-based KPIs, forcing new agencies to repeat the same mistakes. The strongest leaders use the moment to tie PR to real business outcomes while accounting for AI-driven discovery platforms where third-party validation shapes perception. Done right, a PR agency change turns PR from a cost center into a durable growth asset.
