Analytics firm Localytics raised $35 million in funding, which it said will be used to bolster its “predictive intelligence capabilities, which enable customers to truly personalise the user experience and improve engagement in their mobile and web apps”.

The company is looking to provide customers with data that enables them to “predict and proactively engage app users at all stages of the customer journey”, including predicting a user’s likely next move and “how to influence the desired action”.

Localytics said it now supports 32,000 apps across 2.3 billion devices, for a number of customers including HBO Now, Nordstrom, NOOK, and MyFitnessPal.

Its 2014 revenue was 2.5 times that of the previous year, although the privately-held company has not revealed what that means in real terms. It has 200 employees in the US and the UK, and intends to “build out its team throughout 2015”.

To date, it has raised $60 million. New investor Sapphire Ventures led the round, with participation from existing investors Foundation Capital and Polaris Partners.

Doug Higgins, MD at Sapphire Ventures, said: “App marketing is seeing tremendous growth, and Localytics has the strongest customer base and the unique combination of app marketing and analytics needed to dominate this category.”
