After a two-year technical degree in agriculture, Philippe Royer gave up becoming a farmer like his parents, to start a career as an agricultural advisor in a dairy control company, which he took over at the age of twenty-nine. He continued his career in this field and in 2015 he became the General Manager of the cooperative livestock consulting group Seenergi. He is also the owner of the Corneille Fnac bookstore in Laval. Between 2018 and 2022 he was the president of Christian Entrepreneurs and Leaders and in 2022 he published in such capacity “S’engager pour le bien commun” (lit. Committing to the Common Good), a book in which he invited to engage in the world through humanistic entrepreneurship.
