Big Bloom is a non-profit organization whose members are the organizers of hackathons in France and around the world.
A consultant specializing in leadership development programs, Yvan Gatignon created Big Bloom at the request of Air Liquide, BNP Paribas, Engie, Enedis and L’Oréal which wanted to provide their talents with a training that enabled them to embody the societal mission of their company.
The first hackathon for good was launched on December 13 and 14, 2018 in Paris. Big Bloom spread in 2019 in Brussels, Lisbon and Singapore. In 2021, Big Bloom is already present in ten countries.
