Twilio has been used by two winning projects in its government contest: Mobile Commons and FixMyCityDC. The former is a platform that enables citizens to contact their local representatives through various channels, including web interface, SMS, or phone call. It also features an open-source legislative district lookup tool and an address book of over 20,000 capital and district offices for federal and state representatives. The latter is a reporting tool for public issues, which can be resolved by city services, allowing taxpayers to track progress and ensure accountability. Both projects utilized Twilio's voice application capabilities to simplify telecom and enhance citizen engagement with government services.
