App marketing platform Localytics has raised $35m (£23.5m) in Series D funding.

The investment round was led by Sapphire Ventures, alongside existing investors Foundation Capital and Polaris Partners.

The funds will be used to strengthen Localytics’ predictive intelligence capabilities, as it develops a platform that promises to predict app user behaviour and pro-actively engage them at all stages of the customer journey.

Alongside announcing this funding, the company is opening a private beta for the first use case of this technology – predicting and preventing churn.

“Companies are struggling to keep up with the growth of apps. Most are unable to leverage user intelligence to improve how they acquire and engage users,” said CEO Raj Aggarwal. “Localytics’ investments in predictive app marketing will enable us to deliver the amazing, personalized app experiences that consumers have come to expect.

“With its deep history in scaling successful marketing technology companies such as ExactTarget and Criteo, Sapphire Ventures’ expertise will help us continue building the leading solution for apps.”
