New No. 1 and a host of newcomers join the list of top Pacific Northwest tech startups – GeekWire

There is a new number.

Fusion Power Company Helion Power took the top spot in the latest edition of the GeekWire 200, our quarterly ranking of the top privately held tech startups in the Pacific Northwest.

Helion replaces Highspot, which announced a merger with Seismic in a major software deal last month (outgoing companies complete the list). Backed by the likes of SoftBank and Sam Altman, Helion announced two major milestones in February in its quest to produce usable energy through fusion reactions.

The company’s rise to the top of the GeekWire 200 reflects a broader trend in the rankings, as startups building sophisticated hardware across sectors such as space, energy, robotics, and agriculture make up the bulk of the list. It’s a significant change for a region often dominated by enterprise software.

The top 10 include companies such as Agility Robotics, which builds humanoid robots; Brinc, a drone maker serving public safety clients; Stoke Space, a space production company; and Carbon Robotics, which sells weeding equipment to farmers. Seattle VC firm Ascend has dubbed this crop of companies “Cascadian Dynamism.”

The GeekWire 200 is a great resource to help track the region’s emerging companies, as well as established leaders.

The list, which dates back to 2013, includes destination data and planning information to provide a comprehensive overview of the region’s primary location. The GeekWire 200 has long served as a resource for investors, job seekers, service providers, and others tracking the Pacific Northwest tech scene.

Here are 10 new ones.

Notes on GeekWire 200

Our list is not scientific, by any means, and some rankings should be taken with a grain of salt. But it has proven to be a very useful tool. We regularly hear from readers who use the GeekWire 200 to look for jobs, prospect clients, mine potential investments, and get a high-level view of the tech community.

We also use the list as a valuable insight tool, collecting survey data to highlight trends among fast-growing startups.

Standards have changed over time, and last year we made some important changes.

  • We look at each company’s workforce growth over the past 12 months, looking at both the percentage increase and the number of jobs added.
  • Large companies still gain credit for maintaining scale – a sign of maturity and customer traction. But this has less weight than growth, to help emerging players stand out.
  • We include LinkedIn follower statistics as a rough measure of a company’s social traction. To avoid selecting older established firms, we use a curve that favors smaller firms.
  • And as in the past, we consider editorial judgment from GeekWire’s news team, based on factors including recent funding and layoffs, as well as our own insights into regional tech startup coverage.
  • Companies founded 15 years ago or later are “graduated” from the GeekWire 200, and are not included. We also remove companies due to mergers, acquisitions and private equity deals where they sell a majority of their shares.

To make sure your Pacific Northwest tech startup qualifies for the GeekWire 200, first make sure it’s included in GeekWire’s extensive startup list. If so, there is no need to submit it separately. If your startup isn’t among the companies on that big list, you can submit it for inclusion here, and we’ll crunch the numbers to see if your company makes the next GeekWire 200 update.
