# The 50 largest managed service providers in New York State

Tamtam tracks 78 managed service providers headquartered in New York State. This list ranks the 50 largest by number of employees on LinkedIn, led by IBM, Kyndryl and MongoDB. Their median headcount is 591. Half of them were founded in 1996 or later. The most common headquarters are New York (36).

These managed service providers in New York State are mostly IT services and software development firms, with a presence of financial services and media companies. The list includes large corporations like IBM, a technology and consulting giant, and Kyndryl, which manages advanced technology infrastructure. Mid-sized firms such as MongoDB, a developer data platform, and Presidio, focused on digital transformation and cloud computing, are also featured. The state's own NYS Office of Information Technology Services is also present.

A clear pattern is the concentration of headquarters in New York City, hosting a significant number of these companies. Many of the listed firms, like Astronomer (founded 2018) and CoreWeave (founded 2017), are relatively young companies established in the last decade, indicating a recent growth in the tech and managed services sector within the state.

## 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.
