Sharing new ideas on city governance around the world

Bloomberg Philanthropies

In 2022, Bloomberg Philanthropies held its first-ever Global Mayors Challenge, an innovation competition to support and spread cities’ most ambitious ideas.

The opportunity

With winners spanning 15 cities hailing from 13 nations on 6 continents and collectively representing more than 30 million residents, Bloomberg Philanthropies set out to stage an announcement that was truly global in scale, including in-depth local coverage.

The solution

Our global network played an essential role in securing exclusive local media stories on 6 continents, in 9 languages, and in 14 different time zones. Our core team in the U.S. coordinated meetings between the client, each city’s mayor’s office, and local experts. Our media relations experts proposed securing a global exclusive with the Associated Press.

On the ground in each city, we proposed working with mayors to secure an in-depth local exclusive story of the award-winning programs and coordinating interviews with local officials and a spokesperson from Bloomberg Philanthropies.
