The most common headquarters are New York (12), Dallas (2) and Oakville (2). These North American information services companies offer a range of data, analytics, and expert-driven insights. They include large established firms such as NielsenIQ, founded in 1923, which provides consumer intelligence and global retail data, and Experian, founded in 1980, a global information services company.

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.
