Since the creation of The Allyance in 2020, Caroline has worked with companies such as Believe, Doctolib, Kering and Google.

Léa Chemardin-LISS
Je m’appelle Léa Chemardin-Liss, J’ai rejoint The Allyance dès sa création, un an et demi après ma rencontre avec Caroline, au concert de ionnalee ! Je suis traductrice et rédactrice de contenu freelance, surtout en langues française et anglaise, mais aussi en espagnol et allemand, que je parle couramment. Du côté militant, j’ai eu de nombreuses occupations bénévoles dans des associations traitant de thématiques sociales et environnementales.
Aujourd'hui, je suis plutôt engagée dans la sensibilisation aux handicaps invisibles qui me concernent. Mon but est toujours de mettre l’intersectionnalité et la convergence des luttes au centre, car je suis persuadée que toutes les causes sont interconnectées. Si vous avez besoin de recommandations lecture, je suis la personne à contacter !”

Romain Lerallut, VP Head of Criteo AI Lab
"I had the chance to meet Caroline at Criteo a few years ago. Since then, I never stopped to be amazed at her professionalism, charisma, and ability to always over-achieve any goal she sets for herself. She is committed to making diversity a reality, which is not fancy word for her but a dire necessity worth fighting for. I love working with her and consider myself very lucky to have crossed her path."
Sami Touil, CTO at Alma
“At the end of 2019, when I painfully decided to stop my PhD, Caroline Chavier has been very supportive and promptly offered her help! She helped me to define and express what I was expecting from my next job and company, carefully commented my resume, and trained me for interviews. In other words, she had the whole candidate process in mind and assisted me on each step. Her dynamism and reactivity were incredible boosters! If you are looking for someone who can treat your candidates with passion and kindness, she is the one!”
