The growing Proyecto Cities network stages many events to share findings between its participant cities, which is also open to newcomers. Many cities decided to apply the Proyecto Cities methodology on their own accord, while feeding their findings back to the city network. Together, their empirical findings provide an opportunity to continuously adapt the methodology to new challenges and to enrich the new approach of the Fundación Metrópoli to urban development elaborated in Territorios Inteligentes.

The formal core of the Proyecto Cities network encompasses Arriyadh, Barcelona, Bordeaux, Boston, Bucharest, Casablanca, Curitiba, Dubai, Dublin, Euskal Hiria, Hong Kong, Lisboa, Madrid, Marseille, Marrakech, Medellin, Miami, Milan, Monterrey, Montevideo, Philadelphia, Santo Domingo, Shanghai, Singapore, Sydney and Toronto.
