Born in the South of Brittany, in Vannes, Firmin Thétiot began playing football with local clubs. First with St Avé from U8s to U12s then with Vannes OC U13s to the U15s. In July 2024, he was enlisted by the Stade Rennais Academy setup. The versatile defender was put into a higher age category and played for the Rennes side which played in the Coupe Gambardella (French FA Youth Cup). He made five starts on their cup-run, even scoring a goal in the semi-finals. His performances earned him a first professional contract with the Red and Blacks, which he signed on 10th November 2026, in a four year deal, keeping him at the club until 2030. His success didn't go unnoticed at national level, either. The French U17 team picked him at the same time to represent his country for the first time at youth level, at the U17 World Cup in Qatar (from 19th November to 13th December 2026).
