Being data-driven helped grow QuizUp from a hot new game that could acquire users into a social platform that could keep them around. They worked to understand how people were using their app, and what actions lead a user to be retained. Then they worked as a team to develop QuizUp’s social features and solve the second half of the growth formula. In the process, by utilizing usage data throughout the development process, they created the thing that their customers had been telling them they wanted all along.
