Danger, Inc. was a Palo Alto, California mobile computing company founded on December 9, 1999 by Andy Rubin, Joe Britt, and Matt Hershenson, all former Apple, WebTV, and Philips engineers. Danger built the Danger Hiptop, sold in the United States as the T-Mobile Sidekick, an early client-server ("cloud") smartphone whose downloadable application catalog prefigured the app stores later shipped by Android and iOS. Andy Rubin left Danger in 2003 to found Android. Microsoft acquired Danger on February 11, 2008 for a price reported at roughly $500 million and folded the team into "Project Pink," which shipped as the short-lived Microsoft Kin. Most former Danger staff had left Microsoft by October 2009 and the company was wound down by approximately 2011. Danger was surfaced in the API Evangelist network as a historic Redpoint Ventures portfolio holding. It is defunct: the danger.com domain no longer resolves and there is no developer portal, documentation, or API surface to catalog.
