Appcelerator raises $2.1M to build apps on multiple devices

Appcelerator, the maker of an open source platform for building desktop and smartphone applications, has raised $2.1 million in new funding.

The Mountain View, Calif. company took its Titanium platform out of beta testing in March. It gives Web developers the tools to build apps for computer desktops, iPhones, iPads, and Android devices using languages they’re familiar with, including HTML, CSS, and JavaScript. At the time, Vice President of Marketing Scott Schwarzhoff said much of the company’s recent work involved improving the technology so that Titanium apps performed as well as those developed natively for each device.

There’s one big question right now for cross-platform technologies like Appcelerator — whether or not they will continue to work on Apple’s iPhone and iPad. With the upcoming version 4.0 of the iOS operating system, Apple’s new developer agreement suggests that it will be blocking apps that aren’t built using native technologies. Appcelerator chief executive Jeff Haynie commented on the issue on the company blog, saying Titanium is “fully in compliance with iPhone OS 4.0 [terms of service] as we interpret them” and noting that Apple’s main target with these rules seems to be Adobe.

We spotted the latest funding in a filing with the Securities and Exchange Commission, and Appcelerator confirmed it via email. The company declined to offer any details on the funding, so it’s not clear who provided the new round. However, the filing doesn’t list any new board members, so it probably came from Storm Ventures and angel investor Larry Augustin, who previously provided Appcelerator’s $4.1 million first round.
