280 North was a web software development startup company formed in 2008 by college friends Tom Robinson, Francisco Tolmasky, and Ross Boucher.^[1] It was purchased by Motorola in 2010.^[2] Tolmasky and Boucher both previously worked for Apple, on the iPhone and iTunes respectively.^[1]

They created a software stack that includes Objective-J, which relates to Javascript in the same way that Objective-C relates to C, and Cappuccino, which is a port of the Apple Cocoa API. Cappuccino and Objective-J have been released as open source software.^[3] Their first major release was 280 Slides, which is presentation software similar to Apple's Keynote or Microsoft's PowerPoint, but that works entirely in a web browser using JavaScript.^[1] Their next project was a drag-and-drop visual integrated development environment for web applications named Atlas, which could work with the iPhone API. Atlas was to be open-sourced, but, after acquiring 280 North, Motorola decided to keep Atlas private.^{[4][5] [6]}
