Top 5 Global B2B Agencies 2026
Great news: the 2026 Global Agencies Benchmarking Report has just launched, with fresh insight into the agency landscape, complete with the top 5 global B2B agencies of the year. Read on to see which agencies made the cut and who took the #1 spot.
Before we dive in, it’s worth noting that we asked agencies to share financial data from their most recently closed financial year. We then ranked them by gross income, converted to dollars. We also surveyed 14 agencies this year, compared with 15 last year, so keep that in mind when reviewing the rankings.
So who claimed the top spot? Here’s our top 5:
- Dentsu B2B
- Gravity Global
- Global Agility
- VCCP B2B
- Marketbridge
Dentsu B2B claimed the top spot, making it the first agency in our series to rank #1 in the UK, US and globally in the same year. Coming in second place is Gravity Global, who won ‘Global B2B agency of the year’ at our 2025 B2B Marketing Awards last year.
The standout financial trend this year is the slight decline in average gross income, from $58.01 million to $57.2 million.
Although the drop is small, it marks a break from the upward trajectory seen in previous editions of our benchmark and suggests agencies are operating in a more challenging commercial environment.
Even so, the broader picture is one of optimism. Almost every agency surveyed expects to grow over the next 12 months, with only one forecasting flat performance and none expecting further decline. That suggests agencies see recent performance as a temporary slowdown, not a long-term shift in demand.
