The professional services firms in Morbihan are primarily small to mid-sized companies, with a strong presence in IT services and consulting. Many were founded in the 1980s and 2000s. METI, for example, specializes in business process management solutions for retail, while isatech provides ERP & CRM solutions and Microsoft Dynamics 365 expertise. OJC Conseil offers IT services for purchase, sales, and treasury management, and Pros-Consulte focuses on preventing psychosocial risks and enhancing mental health in the workplace.
A notable pattern is the concentration of IT and digital services, with companies like Soledis specializing in e-commerce and web marketing. There is also a cluster of accounting firms such as SAPIENCE AUDIT, which provides tailored support to businesses, and EXCO AR MEN, offering accounting, taxation, and payroll management. Vannes emerges as a key hub, hosting several of these professional services providers.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
