    Developing Video+ for Kayzen

    Role: Vision, Strategy, Architecture & Creative Services

    I developed Video+ as Kayzen’s Creative differentiator. A key project from my time as Creative Solutions Lead at Kayzen.

    What is it? A suite of Mobile Creative Experiences that extend fullscreen video with interactivity engagement data layer

  • Smartphones displaying various mobile app interfaces, including games, quizzes, shopping, and video streaming.

    Video+ Showcase

    My team and I have made 100’s of Video+ Creatives at Kayzen for a variety of advertisers with varied use cases from upper funnel awareness to performance.

    To achieve production at scale, I took a tech-first approach focused on building robust templates with builder tools for tried and tested (by us) experiences.

    Delivered on Kayzen via all of biggest mobile exchanges: Applovin, Chartboost, Digital Turbine, Vungle and more.

    PS: We developed this Ad-Previewer tool as well.

    Case study: COOP + Dentsu + Kayzen

    By leveraging Kayzen’s Video+ ad format, Dentsu delivered a branding campaign that didn’t just inform, it connected, engaged, and converted visitors, setting a new standard for brand engagement and customer acquisition. 

    Read The Case Study
  • A person using a laptop displaying a webpage titled 'Why Interactive Ads Win: Kayzen’s Vision For Data-Driven Marketing,' featuring text, a profile picture, and a quote from a creative solutions lead. Another laptop is visible in the background.

    Upper funnel engagement data that drives lower funnel performance

    Built into the architecture is a layer of rich data capturing and performance tracking.

    Allowing us to not only track all of the ad performance metrics you’d expect but also additional engagement metrics and interaction data that signals intent.
