馃嚭馃嚫 Ohio100 companiesUpdated Nov 11, 2026

This list features large companies in Ohio with in-house R&D departments. The prominent sectors are manufacturing, particularly industrial machinery, paint, and motor vehicles, alongside a strong presence of healthcare and higher education institutions. Notable companies include Procter & Gamble, which designs and sells consumer goods, Parker Hannifin, a global leader in motion and control technologies, and Sherwin-Williams, a global supplier of paints and coatings. Cleveland Clinic is a not-for-profit academic medical center, and GE Aerospace provides jet and turboprop engines.

A clear pattern among these companies is their long-standing presence, with many founded in the late 19th or early 20th centuries, such as The Goodyear Tire & Rubber Company (1898) and Dana Incorporated (1904). There is also a concentration of headquarters in major cities like Cincinnati, Cleveland, and Columbus, indicating these urban centers as key hubs for research and development activities in Ohio.

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 11, 2026.
