Early beginnings Between 2003 and 2008 Griveaux began working for
A Gauche en Europe, a think-tank founded by
Dominique Strauss-Kahn and directed by
Michel Rocard. He worked as an adviser to Strauss-Kahn and supported his
unsuccessful bid for the leadership of the
Socialist Party in 2006. He founded Mediane Conseil, a recruitment consultancy, the same year. In 2008, Griveaux stood as a Socialist in both the municipal and departmental elections in
Chalon-sur-Saône, which took place simultaneously that year. He succeeded in winning a seat as both a municipal councilor for Chalon-sur-Saône and a departmental councilor for
Saône-et-Loire. He later became vice-president of the Departmental Council, which was then led by
Arnaud Montebourg. In 2012 he worked on
François Hollande's campaign for the presidency and after Hollande's election served as an adviser to
Health Minister Marisol Touraine.
Career in the private sector, 2014–2016 In 2014 Griveaux renounced his mandates in order to take up a post with the commercial real estate company
Unibail, prompting criticism from a local official. In the
2017 legislative elections Griveaux stood for
La République en Marche! in the
fifth constituency of Paris, where his opponent was
Seybah Dagoma, a Socialist assembly member since 2012. Griveaux won the seat on 18 June with 56.27% of the vote. On 21 June 2017, Griveaux was appointed to the
second Philippe government as a
secretary of state at the
Finance and Economy Ministry, a newly created role. The
Huffington Post reported the extent of Griveaux's remit is unclear, and that he will serve as deputy or assistant (Fr:
adjoint) to Finance Minister
Bruno Le Maire.
Libération referred to Griveaux as ‘the president’s eyes and ears’ in the upper echelons of the powerful Finance Ministry. In February 2020 Griveaux abandoned his bid to become mayor of Paris after it was alleged that he had "exchanged intimate mobile phone messages with a young woman and sent her an explicit video of himself masturbating", which was later posted online by
Petr Pavlensky. Pavlensky said that Griveaux was "only the first politician that he would target: he had only just begun". ==Controversy==
