The largest companies in the Yonne department include a mix of industries, with a notable presence of retail, healthcare, and public administration entities. These are predominantly mid-sized to large organizations, reflecting established operations in the region. HMY, for instance, is a global services leader in retail solutions, while Berner France distributes tools and consumables for professionals.

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.
