Case Study: Clim8 Invest achieves a 42% increase in ad engagement with Attest

How Clim8 Invest increased ad engagement by 42%

Clim8 Invest, a climate impact investment app, faced a creative dilemma before launching its first video ad: two concepts — a practical, future-focused spot showing wind turbines and electric cars, and a warm, emotion-led film — and they weren’t sure which would best resonate with their slightly older, wealthier target audience. Clim8 used Attest to run creative testing and target-consumer surveys to evaluate which approach would convey their message most effectively.

Using Attest’s survey-based creative testing with embedded draft videos and open-text feedback, Clim8 found the emotion-led ad significantly outperformed the practical concept, prompting tweaks (even changing the dog breed) and a broader shift in marketing. The Attest-led test delivered measurable impact: a 42% increase in ad engagement, a 0.71% click-through rate and a 6× CTR improvement for learners, plus higher CTRs across other digital formats as Clim8 repositioned toward a more human, hope-driven message.
