These Spanish companies are primarily large professional services firms, with a strong emphasis on legal and business consulting. Many are well-established entities, some with a history spanning several decades. For instance, PwC España, founded in 1929, provides audit, tax, and consulting services, while Garrigues, established in 1941, offers legal and tax expertise. Cuatrecasas, founded in 1917, is an international law firm specializing in business law.
A significant concentration of these large firms is located in Madrid, including KPMG España, which provides audit, tax, and legal services, and Uría Menéndez, an international law firm. This suggests Madrid is a central hub for professional services in Spain. Another notable entity is Ilustre Colegio de la Abogacía de Madrid, founded in 1596, which defends the legal profession in Madrid.

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 13, 2026.
