Born on 27 October 1968 in Grenchen, Switzerland, Auderset was converted to Christianity after reading the French comic magazine Tournesol as a child.

In 2001 he released his first book, Conventional Wisdom, which has been translated into six additional languages (German, English, Portuguese, Spanish, Chinese and Danish) since it was originally published in French.

Since 2010 Auderset has been doing a stand-up comedy routine entitled "The Non-practicing Atheist," touring both in Europe and the Canadian province of Québec.

In 2012 Moondog Animation Studio in Charleston, South Carolina, raised US$117,534.00 through a crowd funding campaign on Kickstarter to produce five pilot episodes of The life and trials of Willy Grunch, based on Auderset's stories and art.

The five pilots were completed and released in early 2013, and further episodes are slated to begin production in late 2016 as part of an additional Kickstarter project.
