According to PRWeek’s Top 150 League Table, the average PR agency grew just 3.1% last year. Once you adjust for inflation, that’s basically zero.

And yet… some agencies posted growth of over 40%. Cavendish. Taylor Herring. The Romans. Ramarketing. WA Communications. These aren’t scrappy start-ups, either. 

They’re established players pulling away from the pack.

So, what’s really driving the gap between stagnation and success?

That’s the question we set out to answer in our latest Sprint Partners report: The Growth Divide.’

We analysed the strategies of the UK’s fastest-growing agencies and identified 10 key drivers behind their creative and commercial outperformance. Here’s what we found.


Growth Comes from Strategic Discipline, Not Just Great Ideas

Top-performing agencies aren’t just doing good work – they’re building the right growth conditions around it. That means:

  • Investing in a clear point of view – Agencies like Headland and MHP are owning their intellectual space through signature reports, cultural trend tracking, and thought leadership.
  • Embedding AI with intent – Golin is aiming to be the world’s first fully AI-integrated PR agency by 2026. Tangerine is investing over £1.2m in AI to fuel creativity and operational efficiency.
  • Productising services – Agencies are turning know-how into scalable IP. Whether it’s crisis toolkits, brand audits, or planning dashboards, these are not just campaigns – they’re commercial assets.
  • Dialling up strategic advisory – The fastest-growing firms are shifting left on the brief, helping clients with issues like reputation, C-suite coaching, and ESG risk – not just media coverage.
  • Doubling-down on culture and performance – High-growth players aren’t burning out their teams. They’re investing in DEI, retention, leadership, and high-performance mindsets.

In short: they’re watching margin, not just momentum.


Growth Requires More Than Youth and Energy

One in three agencies saw revenue fall last year. A big reason? Over-reliance on junior teams, underpowered by strategic senior talent.

As we’ve written before, creative ambition needs commercial experience to thrive. It’s why Sprint Partners exists – to plug that strategic gap without adding the overhead.


What This Means for Agency Leaders

Whether you’re an MD looking to scale, or a CMO assessing agency partners, the lesson is the same: future growth will be won by those who combine creativity, capability and commercial clarity.

The industry is evolving. Budgets are rising again. But the window of opportunity won’t stay open forever.
