Finding the right global B2B marketing agency has never been more complex, or more consequential. With budgets under scrutiny and board-level expectations rising, the difference between the right agency partner and the wrong one can define an entire year’s pipeline.

Who this report is for:
Client-side marketers looking to appoint or review a global B2B marketing agency will find independent, data-backed rankings and client satisfaction scores that no agency brochure will ever give you.
Agency leaders can benchmark their own performance against 13 direct competitors, with financials, growth trajectories, and client retention data laid out side by side.
What separates this year’s report:
The 2026 edition goes beyond revenue rankings. The new client satisfaction section gives you the qualitative intelligence that the numbers alone cannot: which agencies retain clients year after year, which ones clients actively recommend, and why.
If you rely on referrals, reputation, or gut instinct to choose a global B2B marketing agency, this report gives you something better: evidence.
