This week, Twilio is hosting a developer contest in collaboration with AppHarbor, where developers can submit their best Twilio-hosted app for a chance to win prizes including $500 in AppHarbor credit and $100 in Twilio credit. The contest runs until February 6th and encourages developers to try Twilio for different use cases and industries. The winners will be selected by representatives from Twilio and AppHarbor, with bonus points awarded for providing helpful materials that demonstrate the value of the app or explain how it could become a business someday.
