These North American companies primarily conduct scientific research and development across various domains. Many are government-affiliated laboratories or academic institutions, alongside private firms offering specialized research services. The focus areas include national security, energy, environmental science, and biomedical advancements. These are mostly large institutions with substantial employee counts.

Key organizations include PPD, offering global clinical development services; Los Alamos National Laboratory, focused on national security and advanced science; OpenAI, an AI research and deployment company; and Battelle, a science and technology company solving critical issues through R&D. A notable pattern is the significant presence of federally funded research and development centers, often managed by universities or non-profit entities, indicating a strong government investment in scientific inquiry.

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 14, 2026.
