Admen can be considered as bling bling, especially in Cannes.

But they can help great causes with their knowledge on creativity. 

And they love to debate on ads, they think they can guess the ads that will be rewarded next.

But they never have the opportunity to put a stake on their beliefs.


Guess The Lions

The 1st betting website that challenges admen’s creative flair,
while raising funds to finance campaigns for NGOs.



The concept is pretty simple: bet on the ads you think they will win in Cannes. A lot of ads from all over the world are already entered on Guess The Lions HERE, but you can also SUBMIT A CAMPAIGN and bet on it. The more the campaigns, the more the bets and the more we can raise funds.

At the end of the festival, if your creative flair was correct and if your are among the betters with the most winning bets, congratulations! You made a donation to support great causes’ campaigns and you will be rewarded by gifts from our partners.

All the benefits from Guess The Lions will be given to ACT Responsible ( the international association that enhances great causes’ campaigns. Money will then be invested in the “GOOD AD”: a program that amplifies NGO’s visibility, by selecting NGO’s most creative ads and air them to the most people as possible, through dedicated media partnerships. 

With your bets, ACT Responsible will help NGOs like: Action Against Hunger, AIDES, Amnesty International, The Global FoodBanking Network, Greenpeace, Handicap International, Max Havelaar, Surfrider Foundation, UNICEF, United Nations Worldfood Programme…

If you have any question regarding ACT Responsible or the GOOD AD program, please feel free to contact Sophie Guerinet ( or Isabel Kurata (
