She rose to national attention as a result of a viral Facebook video she posted in October 2018 about France's proposed eco-tax to which she was opposed.
Mouraud quickly found herself on regional and national television debating French MPs.
Mouraud slowly became a divisive figure in the movement, being criticized by other yellow vest activists including Priscilla Ludosky and Eric Drouet, and the French media who have accused her of sharing of "fake news".
Despite having previously stated she was apolitical, Mouraud created Les Émergents (English: The Risen) in January 2019 with the intention of running candidates to run in France's local elections in 2020.
The party was to be neither left nor right, and Mouraud did not necessarily see herself as being included on the candidate list.
Mouraud is a proponent of pseudosciences.
When the yellow vest movement started in November 2018, she primarily made a living as a "hypnotherapist, metapsychist, and parapsychologist ".
She has operated a paranormal and ectoplasm center since 2013 in Morbihan.
She is also a composer and accordion player, who has played in dance halls, music venues and music festivals.
