B2B marketers are pulling back on agency investments for brand and communications — and many report gaps between agency performance and their selection criteria. These relationships are being tested further by macroeconomic volatility and the rise of the in-house “agency” accelerated by the advancements in AI.

In this report, we examine the changes B2B marketing leaders expect for agency budgets, satisfaction with agencies, and preferred pricing models.
