Paris | Lyon | Nantes

Sia Partners is an industry leader in France. Working from our global headquarters in Paris and offices in Lyon and Nantes, 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 (of which our CEO, Matthieu Courtecuisse, is president), Institut de l’Entreprise, and Institut Montaigne. Our contribution to public debates, strong media presence, and extensive expertise have made us an opinion leader. 

Currently located off the Champs-Elysées, our Paris office has maintained strong growth since its creation in 1999. Paris is a hub for Consulting by Design, Sia Partners’ concept that combines design and creativity to reshape client projects for next-level impact. This includes FOVE, our creative agency, and nod-A, our Design Thinking center and the home of Makestorming. 

As the birthplace of Consulting 4.0, our Paris office also houses an AI Center of Excellence and Studio, Sia Partners’ 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. With over 40 consultants and more than 35 clients (92% of whom are recurring), the Lyon branch has seen a 35% growth over the last three years. Industries served 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 Partners is continuing its pursuit of growth by opening a new office in Nantes. This new office, by which we aim to cover the entire Grand-Ouest region and reach 20 consultants within two years, will mainly address clients in the Financial Services, Transportation, Retail, Agri-food and Tech industries.

Sia Partners 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. Keen to join? We recruit throughout the year; check out our careers page for current openings!
