Claire Pommet was born on 2 August 1996 in Décines-Charpieu but grew up in Caluire-et-Cuire, a French town in the metropolis of Lyon.

[3][4] Her mother plays the flute while her father, a real estate agent, listened to Michel Polnareff, Serge Reggiani, and Charles Aznavour.

[7] In early 2015, Pomme was signed to Polydor Records and began working on her debut extended play (EP) En cavale.

In October she released her first chanson française album, titled À peu près; it was described as a mixture of pop and folk by Salome Rouzerol-Douglas in Le Figaro.

[20] Later in that month, her collaboration "Everything Matters" with Norwegian singer-songwriter Aurora was released as a single from the latter's third studio album, The Gods We Can Touch (2022).

[21] In May 2022, she published the children's book Sous les paupières with French singer Pauline de Tarragon, who also did the illustrations.

[24] The journalists of Libération and Le Figaro emphasized the quality of Pomme's live performances, during which she primarily plays the autoharp and the guitar.

Other influences include Lady Gaga, Lizzo, Celine Dion,[26] Lily Allen, Camélia Jordana, Cœur de Pirate, Keaton Henson, Aldous Harding,[4] Feist, Sufjan Stevens, Mylène Farmer,[27] Dolly Parton and Kate Nash.

For the 2020 municipal elections in Lyon, she made public her support for the Europe Écologie Les Verts party.
