# List of private equity-backed companies in New York

Tamtam tracks 39 private equity-backed companies headquartered in New York. This list ranks the 30 largest by number of employees on LinkedIn, led by Ness Digital Engineering, Squarespace and Rockefeller Capital Management. Their median headcount is 359. Half of them were founded in 2012 or later.

These New York-based companies, backed by private equity, mainly operate in software development, financial services, and IT consulting. They include firms such as Ness Digital Engineering, a global provider of data, AI, and cloud-powered software engineering services, and Squarespace, which offers a design-driven platform for online brands. Rockefeller Capital Management provides financial advisory and wealth management, while Mill Rock Packaging specializes in consumer packaging.

A notable characteristic of these companies is their relatively recent founding dates; most were established in the 2000s or 2010s, indicating a concentration of younger, growth-oriented firms. This suggests a focus on emerging technologies and evolving service sectors within the private equity landscape of New York.

## 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 15, 2026.
