馃嚭馃嚫 New Hampshire50 companiesUpdated Nov 14, 2026

This selection of companies in New Hampshire highlights a mix of well-established mid-sized to large firms, with a strong presence in technology, manufacturing, and services. Planet Fitness, for example, is a fast-growing fitness franchisor, while Connection provides tailored IT services. Timberland is a global leader in footwear and apparel, and Skillsoft specializes in AI-native skills management for businesses. Bottomline simplifies complex payment workflows, and Allegro MicroSystems is a leader in power and sensing solutions.

A notable pattern is the concentration of headquarters in New Hampshire towns like Hampton, Merrimack, Stratham, Nashua, Portsmouth, Manchester, and Londonderry, indicating a diverse geographical spread within the state rather than a single urban hub. The companies also span a broad range of founding dates, from Albany International Corp. established in 1895 to I-SEC Security founded in 2005, showcasing a blend of legacy and newer enterprises.

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 14, 2026.
