# The 26 largest companies in Binghamton

Tamtam tracks 26 companies headquartered in Binghamton. This list ranks all of them by number of employees on LinkedIn, led by Binghamton University, United Health Services and Lourdes Hospital. Their median headcount is 344. Half of them were founded in 1958 or later.

The largest organizations in Binghamton are primarily public sector institutions in healthcare and education, alongside some established private sector companies. Notable examples include Binghamton University, a public university offering broad education and research programs, and United Health Services, a healthcare system providing comprehensive services. Lourdes Hospital offers compassionate care, while New York State Electric & Gas serves utility customers.

## 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.
