When discussing India’s technology industry, cities like Bengaluru, Hyderabad, Chennai, and Pune often dominate the conversation. However, West Bengal has quietly built one of the strongest IT ecosystems in Eastern India. With Kolkata serving as the state’s technology capital, West Bengal has attracted major IT services firms, multinational technology companies, software exporters, fintech businesses, and fast-growing startups.
