Some of our work

  • You Totally Rock

    You Totally Rock

    You Totally Rock by Jumping Ahead Inc. sends users personalized motivational messages. The app delivers messages daily to 10,000+ users. Messages contain uniquely generated images for each user tailored to their specific challenges and preferences.

    We were tasked by the client with development of the entire system. Requirements included a back-end, admin dashboard, email system, and mobile apps for iOS and Android.


    • Personalized Image Manipulation: We use ImageMagick on a cloud server to generate personalized images for 10,000+ users.
    • Smart Scheduling: Our system “learns” how often the user interacts with the app notifications and emails and then adjusts the “send rate” accordingly. This allows for maximum positive interactions.
    • Viral sharing: End users can generate an image on the fly using cloud software to share an image personalized for a friend.
