Mobile messaging provider Urban Airship has raised $25 million in a fourth-round funding led by August Capital and including Foundry Group, Intel Capital, True Ventures and Verizon. That brings the company’s total raised to date to $46.6 million.

It plans to use the new financing to enhance its push messaging platforms, capitalize on opportunities around digital wallets and Apple’s Passbook, and driving international expansion. The company’s revenue grew more than 400% in 2012 while the size of its staff doubled to 118.

Urban Airship, which powers alerts and other in-app features for brands including CBS Interactive, ESPN, Groupon, shopkick, and Walgreens, in October launched a new service for delivering location-targeted messages in apps. In December, it acquired Tello, which makes tools allowing small business to create their loyalty cards and coupons for Passbook.
