If you haven’t checked it out already, our UK Agencies Benchmarking Report is chock-full of insights about the B2B industry. And if you’re looking for the marketing agency that has gone through the most growth (percentage-wise) YoY, then read our blog below to check out the top 10.
Before we get started, it’s worth noting that the Rising Stars we are highlighting are the top 10 agencies that reported the largest percentage increase in UK gross income. In addition, we did not include larger agency groups or networks. Finally, some agencies haven’t been included in the table, due to the fact that they were founded within the last two years, and the percentage change would be extremely high.
And with that being said, we saw a 5.3% increase overall in the most recent financial year’s gross income from £5.4 million in the previous financial year to £5.7 million. And out of the 83 agencies we surveyed, 73.5% of agencies have grown from the previous financial year. This is certainly a step in the right direction.
In terms of individual agencies, Darwin earned the top spot for agency growth with a 117% increase in YoY growth from 2024 to 2025. The second spot went to Dentsu B2B (who rebranded from Merkle B2B). They managed to rank second in our main league table while experiencing a 55.92% increase in B2B growth. And the rest of the Rising Stars? Well, see the agency ranking below:
- Darwin
- Dentsu B2B
- Accelera
- EvolveBPM
- IMG: Intermedia Global
- Beneath
- Ambitious
- The Creative Consultancy
- Fox Agency
- Petal & Co
It’s also worth highlighting that all 10 of these agencies said they were predicting growth in the next financial year but half of them cited that they found the current state of B2B marketing services to be challenging while the remaining agencies said they thought it was good or strong. So while half of these top agencies are optimistic about the future, they fully expect challenges and hurdles along the way. For a full analysis of the state of the marketplace, click here.
