About Resonance
PR has a problem: It has never been very good at proving its own value.
Sales has Salesforce. Marketing has HubSpot. Finance has Xero. But PR? We’re still juggling spreadsheets, monitoring tools, contact databases and coverage reports, struggling to connect the dots between what we do and what it achieves.
Resonance is on a mission to change that.
Founded by Claire Williamson in London in 2011, Resonance is a strategic communications consultancy working with ambitious B2B technology, professional and financial services businesses. Over 15 years, we’ve expanded to London and Manchester, built an international network and delivered more than 500 campaigns for over 100 technology brands.
Along the way, we’ve watched the communications landscape become more complex. Traditional media has fragmented, influencers have multiplied, and AI is changing how buyers discover and evaluate businesses. Yet much of the PR industry still measures success by counting coverage.
We think it’s time for something different.
We’re championing PR Operations (PR-Ops), bringing the operational discipline of RevOps and MarketingOps to communications. The idea is simple: connect the people, processes, data and technology behind PR so that every decision is better informed, every opportunity is easier to act on, and every outcome is measurable.
And we’re putting that philosophy into practice.
We’ve built Agentcy, our AI-powered PR-Ops platform, with the ambition of becoming the system of record for PR. It connects media intelligence, journalist relationships, campaign activity, AI visibility and measurement in one place. Instead of spending hours piecing together disconnected information, consultants can focus on what matters: building reputations, influencing audiences and delivering results.
Agentcy already underpins every Resonance programme and is available to other agencies and in-house teams. We’re not just developing technology for our own advantage. We’re helping build the infrastructure the wider industry needs.
In 2026, we went further, open-sourcing our AI visibility measurement technology and launching a public index tracking how major AI assistants recommend UK B2B technology PR agencies. Through our leadership of the PRCA AI in PR group, we’re also helping the profession navigate the opportunities and challenges of AI.
Our team brings together PR consultants, journalists, computer scientists and data specialists. Different disciplines, united by one conviction: reputation deserves the same rigour, intelligence and accountability as any other business function.
Resonance and its team are the developers of reputation, and we’re building a future where PR can prove its worth, not just promise it.
