This selection of professional services firms in Italy includes large global networks and significant Italian companies. Many specialize in IT services and consulting, such as Almaviva Group, which provides digital innovation, and Reply, focusing on AI and big data solutions. Other firms, like KPMG Italy and PwC Italy, offer audit, advisory, tax, and legal services. RINA provides engineering, testing, and certification, while Randstad Italia and UMANA SPA focus on human resources.
A notable pattern among these firms is their strong concentration in Milan, which serves as the headquarters for many, including Accenture Italia, BIP, and JAKALA. This suggests Milan is a central hub for professional services in Italy. The list also features a mix of long-established companies like PwC Italy, founded in 1849, and newer firms such as Avvale, established in 2023.

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 12, 2026.
