This list comprises public sector organizations in Chennai, primarily focusing on banking, higher education, and justice administration. Key organizations include Indian Bank, offering diverse financial services, and the Indian Institute of Technology, Madras, a prominent institution for technological education and research. Other notable entities are Anna University Chennai, specializing in engineering and technology, and the High Court of Madras, a historic legal institution.

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.
