Tamtam tracks 94 AI companies headquartered in São Paulo. This list ranks the 30 largest by number of employees on LinkedIn, led by Atento Brasil, Stefanini Group and AlmavivA Experience. Their median headcount is 2,144. Half of them were founded in 2010 or later.

The companies in São Paulo listed here are primarily large firms in IT services, consulting, and business process outsourcing. Many specialize in digital transformation, customer relationship management, and technology solutions.

## 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.
