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.
A significant pattern among these organizations is their long-standing presence in Binghamton. Many were founded in the early to mid-20th century, such as Lourdes Hospital (1925), Mirabito Energy Products & Convenience Stores (1927), and Security Mutual Life Insurance Company of New York (1886), indicating a mature local economy with deeply rooted institutions.

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.
