This selection of North American research institutes primarily comprises large public and private universities. These institutions are dedicated to advancing knowledge, providing education, and conducting research across various fields. Examples include the University of California, educating top minds and driving innovation, Harvard University, focused on teaching, learning, and research, and the University of Michigan, dedicated to excellence in knowledge and leadership development. Also present are major healthcare systems like Northwell Health, the largest New York healthcare system, and Mount Sinai Health System, which conducts transformative research.
A notable pattern among these organizations is the strong representation of higher education institutions, with many founded in the 19th century, such as the University of Michigan (1817) and Penn State University (1855). While universities are spread across the continent, there is a concentration of major healthcare research in New York, with Northwell Health, Mount Sinai Health System, and NYU Langone Health all headquartered there. NASA, founded in 1958, stands out as a government agency focused on space exploration and aeronautics research.

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 12, 2026.
