# List of professional services firms in São Paulo

Tamtam tracks 200 professional services firms headquartered in São Paulo. This list ranks the 30 largest by number of employees on LinkedIn, led by Stefanini Brasil, Accenture Brasil and Progen. Their median headcount is 2,093. Half of them were founded in 1984 or later.

These São Paulo-based professional services firms are predominantly large companies, many with a global presence. They primarily operate in IT services, consulting, and engineering. Stefanini Brasil, for example, is a global IT services provider, while Accenture Brasil specializes in digital, cloud, and security services. Progen and Concremat Engenharia e Tecnologia are prominent in civil engineering, and KPMG Brazil focuses on audit, tax, and advisory services. PwC Brasil offers integrated business consulting, tax, audit, and outsourcing.

The data shows a strong concentration of global professional services networks with a significant footprint in Brazil. Many of these companies, such as Deloitte Brasil and Nelson Wilians Advogados, were established before the 2000s, indicating a mature sector. The presence of multiple Stefanini entities (Stefanini Brasil, Stefanini LATAM, Stefanini EMEA) headquartered in São Paulo highlights the city's role as a strategic hub for international operations.

## 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.
