The companies listed are managed service providers in Pennsylvania, predominantly active in IT services and IT consulting. They include both large established firms and younger companies founded in the 2000s and 2010s. Unisys, with over 23,000 employees, offers digital workplace and cloud solutions. New Era Technology provides global managed technology services, while Sungard Availability Services focuses on cloud-connected infrastructure.

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 11, 2026.
