SRI International
In December 2007, SRI launched a spin-off company, Siri Inc., which Apple acquired in April 2010. In October 2011, Apple announced the Siri personal assistant as an integrated feature of the Apple iPhone 4S. Siri's technology was born from SRI's work on the DARPA-funded CALO project, described by SRI as the largest artificial intelligence project ever launched. Siri was co-founded in December 2007 by Dag Kittlaus (CEO), Adam Cheyer (vice president, engineering), and Tom Gruber (CTO/vice president, design), together with Norman Winarsky (vice president of SRI Ventures). Investors included Menlo Ventures and Morgenthaler Ventures.

MG Siegler of "TechCrunch" wrote that Siri was "great," praising the potential for Siri after losing the beta tag: "The amount of times Siri hasn't been able to understand and execute my request is astonishingly low...Just imagine what will happen when Apple partners with other services to expand Siri further. And imagine when they have an API that any developer can use. This really could alter the mobile landscape."
