# Professional services firms headquartered in the Pas-de-Calais department

Tamtam tracks 25 professional services firms headquartered in the Pas-de-Calais department. This list ranks all of them by number of employees on LinkedIn, led by Yzee Services, Logista Hometech and CERFRANCE Nord - Pas de Calais. Their median headcount is 33. Half of them were founded in 2001 or later. The most common headquarters are Arras (7) and Béthune (5).

This selection of professional services firms in Pas-de-Calais includes a mix of established mid-sized companies and younger firms. Key sectors represented are accounting, IT services, and various forms of engineering and consulting. Yzee Services, with 831 employees, specializes in customer relationship management. Logista Hometech focuses on property maintenance for social housing, while CERFRANCE Nord - Pas de Calais provides accounting and legal advice. MK Energies offers global energy solutions.

A notable pattern is the diverse range of headquarters locations across the department, indicating a decentralized economic activity rather than a single dominant urban center. While Arras hosts several companies like Logista Hometech and ROXYS, other significant firms are based in towns such as Vendin-le-Vieil, Liévin, and Béthune, suggesting a broad distribution of professional expertise.

## 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.
