The three founders of Kwit

Kwit, it’s the story of a developper who wanted to quit

In 2012, Geoffrey made an important decision: "I quit smoking!". This young developer therefore looked for a mobile application that could support and encourage him during this period he was anxious about, as most smokers who choose to quit cigarettes. But the few apps available did not suit him: incomplete, not aesthetic enough and mostly too guilty. Geoffrey dreamed of a playful, empathic and caring application that not only makes quitting smoking easier, but also fun and challenging. This is how Kwit was born.

I received emails from people I didn't know, from all over the world, thanking me for saving their lives… it became an evidence that I had to continue.

If Geoffrey was able to quit smoking thanks to his application, he was not the only one: many users thanked and encouraged him. Some even translated the app that had helped them so much, in order to make it available to their relatives in their local language.

The next step was the association of three friends to continue developping this application, which was helping an increasing number of former smokers not to take up smoking again and to fight withdrawal symptoms. These 3 partners embarked on a real adventure by creating their startup in 2017.

Today, Kwit is a core team of 6 complementary people, experts in their respective fields, supported by addiction researchers, academics and health professionals.
