Mobile app data and insights provider PushSpring has opened a New York City office and hired Patrick Callinan to run it as its director of sales, East Coast.

Callinan joins PushSpring from Mozilla, where he was global content partnership director helping Mozilla scales its business partnerships, and launch a media product within the Firefox browser. He previously held leadership roles at Nielsen, Facebook, Centro, and Experian Interactive.

PushSpring offers data, tools, and intelligence products to advertisers and mobile app publishers. It processes billions of monthly mobile app and device-level signals to create a multi-dimensional classification of mobile app audiences, offering over 170m targetable device IDs. PushSpring Personas and custom audience segments can be accessed via the PushSpring Audience Console and distributed through DMPs, DSPs, and other programmatic platforms.
