Eldest son of Brigitte Macron · Head of Business Consulting Life Science at Oracle

Key facts 2026: Sébastien Auzière, born in 1975 in Amiens (age 50), is a highly qualified statistical engineer and Head of Business Consulting Life Science at Oracle. Contrary to persistent rumours – debunked since 2017 – he has never worked for IFOP, Ipsos or any political polling institute.

Eldest son of Brigitte Macron (née Trogneux) and André-Louis Auzière (who passed away on 24 December 2019), Sébastien has built recognised expertise in health big data and life science consulting. In a context of intense media scrutiny around the Macron family, he opts for absolute discretion.

Portrait: The Man Behind the Name

Sébastien Auzière was born in 1975 in Amiens into a middle-class family. Eldest son of Brigitte Trogneux, a literature teacher, and André-Louis Auzière, a banker, he grew up in an environment that valued academic achievement above all.

Protective elder brother

At 50 in 2026, Sébastien remains the protective elder brother of Laurence Auzière-Jourdan (cardiologist) and Tiphaine Auzière (lawyer, novelist). His quiet, analytical personality recalls that of his father André-Louis.

Academic background

After his baccalauréat, he joined ENSAI (National School of Statistics and Information Analysis) in Rennes, graduating as a statistical engineer in 1999. From 2000 to 2007: Institut Français de la Mode, Paris. In 2007, he joined Kantar Health, then Cerner Enviza, to his current senior role at Oracle.

His expertise in statistical modelling, big data and consulting quietly contributes to innovation in life sciences and healthcare.

In 2017, he provided quiet technical support to En Marche!'s social media and attended the Bercy rally on 17 April 2017. Since then, he has returned fully to private life.
