Appcelerator scores $15 million funding round

Company also announces its the largest 3rd-party mobile apps publisher in Apple, Android stores

As the mobile device market continues to expand, demand for mobile applications -- and tools for developing mobile apps -- is accelerating.

One company trying to serve the needs of mobile apps developers is Appcelerator, which on Tuesday announced a $15 million round of funding from several sources, including Mayfield Fund, TransLink Capital, Red Hat, eBay, Inc., Sierra Ventures and Storm Ventures.

Appcelerator also announced it is now the largest third-party publisher in Apple's App Store and Google's Android Marketplace. The company claims it has more than 30,000 mobile apps on 30 million devices and that it "counts 1.6 million developers in its ecosystem."

Founded in 2006, Appcelerator offers web developers a platform and services for building applications for mobile, tablet and desktop devices. Its flagship open source Titanium development platform includes testing functionality and built-in analytics. Titanium is a free download from the Appcelerator site.

The latest (and third) round of financing nearly doubles Appcelerator's total funding, which now stands at $31.5 million. The Mountain View, Calif.-based company's last venture round was in October 2010.

Appcelerator said proceeds from the latest funding round will be used for expansion into Europe and Asia as well as continued development of the Titanium platform.
