 Twilio was founded in 2008 by Jeff Lawson, Evan Cooke, and John Wolthuis and was originally based in both Seattle, Washington, and San Francisco, California.Twilio's first major press coverage, in November 2008, was the result of an application built by Jeff Lawson to rickroll people, which investor Dave McClure used on TechCrunch founder and editor Michael Arrington as a prank.A few days later on November 20, 2008, the company launched Twilio Voice, an API to make and receive phone calls completely hosted in the cloud.
