The Economic Development Department of the City of Warsaw in partnership with the Envisio Foundation organized the third workshop Smart City = Smart Warsaw, regarding investment issues contributing to the context of the development of our city. The goal is to develop, systemic solutions with representatives of the business world, scientific units and organizations of the industry, which in the future will help to create guidelines for initiatives taken by the City Council. Warsaw is increasingly becoming part of the concept of a Smart City, but it still faces many challenges. Issues in the area of the smart city require cooperation between various partners: the public side, enterprises, startups, investment funds. By strengthening cross-sectoral dialogue, we try to generate a better future for our city.
