It's plain talk around how you can net high-value users and keep them coming back when our host Peggy Anne Salz catches up with Simon Lejeune, Head of User Acquisition at Hopper. The travel app uses big data to predict and analyze airfare to provide users with the latest and best deals on flights. Simon shares the tools and channels that have allowed Hopper to stay top of mind with users (even when they aren't looking for pricing information and updates). In addition to lifting the lid on his growth stack, he discusses how marketing teams can combine acquisition and retention to break down the silos and super-charge ad creatives.
