What We Do
Twilio is a cloud communications (IaaS) company based in San Francisco, California. Twilio allows software developers to programmatically make and receive phone calls and send and receive text messages using its web service APIs. Twilio's services are accessed over HTTP and are billed based on usage. Twilio's first major press coverage 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 the company launched Twilio Voice, an API to make and receive phone calls completely hosted in the cloud. Twilio's text messaging API was released in February 2010, and SMS short codes were released in public beta in July 2011. Twilio supports the development of open-source software and regularly makes contributions to the open-source community. In June 2010 Twilio launched OpenVBX, an open-source product that lets business users configure phone numbers to receive and route phone calls. One month later, Twilio engineer Kyle Conroy released Stashboard, an open-source status dashboard written in the Python programming language that any API or software service can use to display whether their service is functioning properly or not. Twilio also sponsors Localtunnel, created by now ex-Twilio engineer Jeff Lindsay, which enables software developers to expose their local development environment to the public Internet from behind a NAT.
