# The 100 largest multinational companies in Washington State

Tamtam tracks 288 multinational companies headquartered in Washington State. This list ranks the 100 largest by number of employees on LinkedIn, led by Amazon, Costco Wholesale and Microsoft. Their median headcount is 2,367. Half of them were founded in 1996 or later. The most common headquarters are Seattle (39), Bellevue (17) and Redmond (9).

This list contains large multinational companies based in Washington State, primarily operating in software development, retail, and IT services. Companies like Amazon, a major e-commerce and cloud services provider, Microsoft, known for its software and hardware, and Costco Wholesale, a global warehouse club retailer, are prominent. Other significant firms include Starbucks, a global coffee company, and Expedia Group, a tech company in the travel industry. The list features companies with substantial employee counts, indicating their large scale.

A notable pattern among these companies is their concentration in the Seattle metropolitan area, with many headquartered in Seattle itself or nearby cities such as Redmond and Bellevue. This geographic clustering suggests a regional hub for technology and retail giants. The presence of both established corporations and more recently founded entities like Amazon Web Services (founded in 2006) and Coupang (founded in 2010) indicates a mix of long-standing industry players and newer ventures.

## 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.
