eBay Invests In Appcelerator As Part Of A $9 Million Round

Mountain View, Calif.-based Appcelerator has raised $9 million in funding to help build out its mobile commerce offering as part of its platform that makes developing applications easier.

The second round was led by Sierra Ventures, along with eBay (NSDQ: EBAY) as a strategic investor. Existing investors Storm Ventures and Larry Augustin also participated. The funding was made today at PayPal’s developer conference in San Francisco, where Appcelerator said it was partnering with PayPal to make it easy to build commerce into native applications, for mobile devices, tablets, connected TVs and more.

Appcelerator uses web technologies to help developers build native applications, and now it will make it easier for merchants to sell digital and physical goods and services within applications using PayPal’s platform. Its tools are being used by 77,000 web developers, who have built 5,000 applications (up from 100 at the beginning of the year). Through the partnership, it will offer something called Titanium+Commerce, which is PayPal’s Mobile Payment Library on top of Appcelerator’s Titanium development platform. The program is in beta today and is expected to be available in early 2011. The full release here.

The mobile commerce space is hot with many companies raising millions of dollars in venture capital to go after incumbents, like Visa, MasterCard and even PayPal as the next dominant form of payment. Some of these players include Boku, Zong and mopay. In a keynote this morning, PayPal said about 1,000 apps have been built using PayPal’s billing platform, and that it expects to generate more than $700 million in mobile commerce revenues this year, which is 30 times larger than it was two years ago.
