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.

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.
