The 2026 AI and Marketing Performance Index


A new study from GrowthLoop and Ascend2 Research reveals that despite the flood of AI resources and platforms, marketers still struggle with painfully slow campaign cycles.
The 2026 AI and Marketing Performance Index found that 41% of marketers take 30+ days to execute a campaign. And a whopping 77% say that their "winning" marketing tests fail to scale at least sometimes.
The research, based on responses from more than 300 senior marketers across North America, delves into the strategies and secrets of high-growth marketing teams — and the roadblocks that keep laggards behind.
