Sia is an industry leader in France. Working from our global headquarters in Paris and and in several French regions, we serve clients in both the public and private sectors, including mid-sized companies and nearly all of the CAC 40. We are members of a number of think tanks and trade associations, including Syntec Consulting, Institut de l’Entreprise, and Institut Montaigne. Our contribution to public debates, strong media presence, and extensive expertise have made us an opinion leader. 

With a headquarters currently located near the Champs-Elysées our Paris office has maintained strong growth since the firm's creation in 1999. Paris is a hub for AI and Data, Digital and Design, which we combine to reshape client projects for next-level impact. 

Our Paris office also houses an AI Center of Excellence and Studio, Sia’s investment arm with a diverse portfolio of startups. 

Our Lyon office was opened in 2012 to foster a closer relationship with the local market in France’s second-largest economic region. The Lyon branch has seen a 35% growth over the last three years. Key industries include Energy and Utilities, Insurance, Banking, Public Transport, Manufacturing, and the Public and Health Sectors. Our Lyon office regularly hosts client events across these industries. 

In 2021, Sia continued its growth and opened two new offices, in Nantes and Marseille. 

The Nantes office will address industries such as the Financial Services, Transportation, Retail, Agribusiness and Tech sectors. In parallel, the Marseille office, which aims to reach 20 consultants within two years of opening, will mainly address clients in the Manufacturing, Banking, Environment and Energy sectors.

In the past four years, we have opened offices in Bordeaux and Lille, and most recently, the Sentier neighborhood in Paris' (France's answer to Silicon Valley). 

Sia France has been named one of Glassdoor’s Best Places to Work and has been awarded Choose My Company’s Happy Trainees distinctions several years in a row. The firm has also ranked in the Top 20 Consulting Firms by Vault.
