David K. Pham won the Twilio Developer Contest for Conferous, an elegantly simple way to set up a professional conference line for businesses, with a application built using Ruby on Rails and the Twilio gem, which was completed in just 4 days during his college's fall break. The application uses jQuery for front-end interactions and is designed for businesses without a single physical location or employees working remotely across different time zones. Pham sees Conferous as ideal for online chat-based businesses, but also recognizes the importance of phone conferencing in traditional business settings. He praises Twilio's API for its simplicity and flexibility, which inspired his creation of Conferous.
