Unveiling the Elite: Top 10 B2B Marketing Agencies in the U.S.
Exciting news on the horizon! We’ve just released our comprehensive 2025 US Agencies Benchmarking Report, dissecting the top 10 B2B marketing agencies in the United States. This report highlights key metrics such as gross income, year-over-year growth, specializations, and headcount.
Inside the Report: Data You Can Trust
Every year, our benchmarking report sheds light on the ever-evolving landscape of U.S. marketing agencies. Our approach is meticulous: we request financial data from agencies based on their most recently closed financial year and rank them purely on their gross income. Out of the 29 agencies surveyed, 24 reported their fiscal year ending in December 2025, while others concluded their years in January, February, October, November, and June. For context, we surveyed 33 agencies last year, compared to 29 this year; so it’s essential to keep this variability in mind when interpreting the rankings.

Analyzing the U.S. Marketing Landscape
Taking a broader look at the U.S. marketplace, we noted a 25.9% YoY increase in gross income, skyrocketing from $13.5 million last year to $17 million this year. Coupled with an uptick in overall headcount, these indicators suggest promising growth in our industry.
However, it’s crucial to acknowledge that the economic landscape has shifted significantly recently. Despite these challenges, this is the highest average gross income reported since 2023. We remain optimistic that these encouraging trends will empower agencies to thrive even amidst uncertainties.
