Twilio and Startup Weekend are partnering to host a series of startup challenges that allow entrepreneurs to test drive entrepreneurship through hands-on experience with APIs, SDKs, sample apps, and other resources provided by Twilio. The events take place over several weekends in November 2009, with locations including Atlanta, Boise, Tulsa, New York, Los Angeles, Bay Area, Cleveland, Dallas, Lexington, London, and more. After the events, a winning team will be announced and get to learn from customer engagement experts through resources such as ebooks, industry reports, webinars, and Twilio's developer community hub.
