Seattle is home to thousands of businesses, both large and small but for right now, we're giving some love to the former. A handful of large companies like Starbucks, Nordstrom and Alaskan Airlines got their start in Seattle but today, a new class of major tech companies are stepping up as employment hubs in the city. According to Statista, nearly 11% of Seattle’s workforce is employed in tech. With that in mind, we've compiled a list of some of Seattle's largest tech and tech-enabled companies for anyone looking to jumpstart their research on the city's tech scene. While this list is far from definitive, we've narrowed it down to only companies headquartered in Seattle with at least 200 local employees in our database.
