The subscription businesses in Boston largely consist of software development and marketing services companies, alongside a significant insurance presence. Notable firms include Liberty Mutual Insurance, a global leader in property and casualty insurance; athenahealth, which simplifies healthcare with innovative technology; PTC, providing solutions for manufacturers; and Toast, empowering restaurants with cloud-based software. These companies primarily focus on B2B solutions, offering specialized services and platforms to other businesses.
Most of these companies were founded in the late 20th or early 21st century, indicating a relatively modern and technology-driven landscape.

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.
