DataCity is an open innovation program created by NUMA in partnership with the City of Paris. The objective is to use data to design solutions tailored for the benefit of tomorrow’s cities.

With the support of multiple stakeholders, we set up experimentation fields to allow startups to test their cutting-edge prototypes. Corporates and local authorities benefit from the solutions through new business opportunities, new services or quality improvement.

  • Engage a local Corporate Ecosystem.
  • Share learnings from other Cities dealing with similar issues.
  • Engage your communities into actual field innovations.

challenges we address
"On top of new working methods and the deeply rooted relationships we built with other sponsors, we are creating a common service offer with Openergy around energy mutualization."
"DataCity addressed the challenges of the modern city with new methods, and allowed Paris City Hall to involve various city services to promote internal transformation of our administration."

“The experience has been very positive, helping us to better identify the challenges faced by our industry, how to overcome them and better size the potential of our products.”
