GrabTaxi is the #1 taxi booking app in South East Asia with over 2.5 million users. The company raised 250 million dollars in funding from SoftBank in 12/2014.

GrabTaxi hired CB/I to run its PPC campaigns to acquire app users for both iOS and Android, and optimized its weekly newsletters to boost engagement.

At the time, Google Adwords was unable to track iOS app installs effectively, thus making it difficult to optimize campaigns for best cost-per-install.

GrabTaxi was sending email blasts weekly that had many issues to be fixed, including call-to-action, messaging, and compatibility.

CB/I helped GrabTaxi optimize the PPC campaigns to reduce cpi for both Android and iOS apps, and setup new PPC campaigns for marketing and branding of GrabTaxi.

CB/I reviewed every weekly newsletter of GrabTaxi, suggested changes, and ran final tests before each blast went out, to improve email open rates and click through rates.
