Their median headcount is 1,603. Half of them were founded in 1968 or later.

The multinational companies in Bangkok are predominantly large, established firms, with a notable presence in the financial and hospitality sectors. Companies such as SCB – Siam Commercial Bank and Bangkok Bank offer diverse financial products and services, while Anantara Hotels & Resorts and Six Senses provide luxury hospitality experiences. Other significant firms include PTT Group, an integrated energy company, and Thai Union Group PCL., a global seafood company.

## 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 12, 2026.
