Success Story

Kellogg’s Crunchy Nut Bertie

Crunchy Nut put together an HPTO - Advertiser Page on Spotify which used iris recognition technology. The user was not permitted to look at the Crunchy Nut Chocolate Curls!

Promote the new range of Crunchy Nut cereal called ‘Crunchy Nut with Chocolate Curls’.


  • HPTO and Billboard Ads driving to an Advertiser Page
  • Once the user landed on the Advertiser Page, we would use their webcam to track their eyes. The user would then begin a game where they couldn’t get distracted by the Crunchy Nut Chocolate curls; if they looked directly at the curls, they would be redirected to begin the game again.
  • No incentive – simply an engaging brand and product awareness piece
