Heatseeker is for marketing, growth, strategy, and innovation teams who need real buyer proof, not opinions. Trusted by CMOs and firms like KPMG and Bain, it helps test ideas fast with real actions and AI avatars.
Heatseeker pricing requires contacting sales, as no specific rates or trial options are listed. Plans vary by features, offering 12, 24, or 48+ experiments annually, with increasing numbers of custom-trained synthetic audiences and expert guidance hours. Optional add-ons include media inclusion and incognito tests using stealth brands, tailored to team size and experimentation needs.
