Company Background

InMobi drives real connections between brands and consumers by leveraging its technology platforms and exclusive access to mobile intelligence. Its Marketing Cloud creates new paths for brands to understand, identify, engage and acquire connected consumers.

A leading performance marketing agency uses highly targeted rewarded campaigns to help mobile marketers find their best customers among audiences who have opted in to receive relevant offers from brands. After signing up for a new subscription, registering for a free trial, or completing a survey, the user is directed to a rewards page. Using the traditional performance model, brands only pay when the desired action is taken. Over time, the Agency noticed a correlation between reward aficionados completing a form or survey, and mobile gamers. Responsible for driving top-of-the-funnel conversions for a diverse portfolio of brands, the Agency wanted a mobile marketing partner that could help them acquire a significant volume of reward-seekers through in-app games and hit day one 100% ROAS.

We are excited to continually work with them to meet and exceed their in-app ad campaign goals."
