THIS IS THE STORY OF A STARTUP THAT IN 3 YEARS SET UP THE WORLD\'S LARGEST GATHERING OF SOLUTIONS FOR THE PLANET. It all began in 2015, when France hosted COP21 and the Paris agreements were being drawn up. At the same time, all over the world, solutions were emerging and new entrepreneurs were putting their creativity and ambition at the service of the world’s major global issues. And yet, these initiatives remained isolated, unknown, and struggled to scale up. The impact ecosystem was still in its beginning. Unlike mature sectors, which all have their own strategic meetings, the impact sector did not yet have its global gathering. The idea of the ChangeNOW summit was here: the impact ecosystem needed its major global gathering to bring together investors, entrepreneurs, corporates, communities and talent, and accelerate synergies and visibility at scale. Carried by a visionary, humanistic and action-oriented spirit, the ChangeNOW adventure was born, federating around it thousands of entrepreneurs and key actors of change: international networks, investors, corporations, communities, ministries, universities, media.
