The companies listed in West Bengal are predominantly IT services and IT consulting firms, with a few diversified conglomerates. Most companies are mid-sized to large, reflecting an established business landscape rather than a startup environment. Many of these firms, such as mjunction services ltd, Indus Net Technologies (INT.), Kaizen IT Services Pvt. Ltd., and Capital Numbers, are headquartered in Kolkata, indicating a concentration of IT services in the region.

Turn this list into pipeline
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.
