# The 30 largest consulting firms in Bordeaux

Tamtam tracks 43 consulting firms headquartered in Bordeaux. This list ranks the 30 largest by number of employees on LinkedIn, led by CF - Compagnie Fiduciaire, EXTENCIA | Cabinet d'expertise comptable and GCL - l'innovation dans l'accompagnement des entreprises. Their median headcount is 38. Half of them were founded in 2011 or later.

These Bordeaux consulting firms primarily offer business, IT, and accounting services, ranging from large established groups to younger companies. CF - Compagnie Fiduciaire provides extensive accounting and auditing services, while EXTENCIA offers specialized accounting and advisory support. Alltech Consulting focuses on IT services and employee development, and NEOSYS delivers digital transformation and IT solutions across Europe and North Africa. This selection illustrates the breadth of consulting expertise available in the Bordeaux region.

The companies show a mix of long-standing firms and more recently founded businesses.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
