If you haven’t checked out our 2025 Global Agencies Benchmarking Report , you’re missing out on some of the best in B2B when it comes to global agencies across the world. And in this blog, we are breaking down the top B2B brand marketing agencies globally. Find out who claimed the #1 spot on our list.
Before we dive into the report, it’s worth noting how we collect data for all our global specialisms. In our global survey, we asked agencies to check off what services and capabilities they offered. This included everything from PR and ABM to sales enablement and much more. After selecting their entire offering, agencies were then asked to use the same list to highlight their top three specialisms. Using the data from this question, we created the brand specialism league tables for the global report. To make it clear what we define as a brand, we stated it as ‘Brand services (includes brand development and communication, plus purpose-led initiatives)’.
We also want to acknowledge that rankings are based on highest gross income. With that being said, let’s see who ranked on top.
Dentsu B2B has claimed the top spot this year, reporting a global gross income of £152 million. The agency also led both our US and global main league tables, underscoring its ability to drive growth from its US offices as well as across international markets.
Close behind are Gravity Global (£117 million) and BBN (£115 million), taking second and third place respectively. Among the 15 agencies surveyed, “brand” stood out as the clear priority as nine agencies listed it among their top three specialisms. This reinforces brand’s growing role as a driver of ROI and long-term growth.
When we spoke to Darren Coleman, Brand Expert, Propolis about our US report, he commented: “Brand building is entering something of a golden era in marketing. We have never had so much evidence to show the commercial value brands add to company value, revenues and margins to name a few. This is particularly important – and encouraging – as historically brand marketers have had a very difficult time convincing the C-suite to invest in brand.”
That sentiment is resonating globally. It’s also reflected in the shortlist for the 2025 B2B Marketing Awards, which features standout campaigns in both ‘Best Brand Initiative’ and ‘Best Brand Initiative (under £100,000)’. Among the highlights is ‘Making Space for Incredible’ by Transmission for AutoStore. Transmission secured 7th place in both our brand specialist and main global league tables.
