Citymart Challenges help cities access the contributions of citizens and entrepreneurs to find proven, innovative solutions to solve their problems.
They ask three simple questions: “What is your idea for solving the problem, how ready is your solution, and how can we measure its success?”
Citymart Challenges are fair and transparent, and proposals will be evaluated by city officials and field experts, offering you valuable feedback.
If you want to be informed about new challenges, please leave your details:
