These US information services companies mostly provide data, analytics, and expert insights to businesses across various sectors. The list includes large organizations like Freelance, which offers journalism and writing services, and NielsenIQ, a consumer intelligence firm. Other notable companies are Experian, focused on data management and fraud prevention, and Gartner, known for its expert-led research. Most of these companies are well-established, with several founded in the 1970s and 1980s.
A significant pattern is the concentration of headquarters in New York, with companies such as Freelance, Freelance Insider, GLG, and Guidepoint based there. Other key locations include Stamford, home to Gartner and ISG, and Chicago, where NielsenIQ is headquartered. These firms primarily serve other businesses, helping them with decision-making, risk management, and operational efficiency.

Turn this list into pipeline
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 15, 2026.
