The tech economy in Seattle and the Pacific Northwest has long been shaped by software, but our quarterly ranking of the region’s top startups signals the rise of companies building physical stuff: rockets, fusion reactors, military robots, and data centers bound for orbit.
Big movers in the latest GeekWire 200 update include companies bioprinting human tissue, fusing atoms, and building autonomous machines. A reusable-rocket maker, Stoke Space, rose to No. 6, while a military-autonomy company, Overland AI, cracked the top 10 for the first time.
Redmond, Wash.-based Starcloud vaulted 96 spots after becoming the fastest Y Combinator company ever to reach unicorn status, at a valuation of $1.1 billion, based on its vision to put solar-powered data centers in space to meet the soaring energy demands of AI.
Atop the list, fusion company Helion held its position at No. 1, now valued at $15.5 billion after raising an additional $465 million as it builds a plant for a new generation of energy.
Another company the top 10, isn’t long for the GeekWire 200. Agility Robotics, maker of the Digit warehouse robot, is going public in a $2.5 billion deal. It’s currently No. 5, and companies graduate from the list once they go public or are acquired.
Software still has a big presence on the list: Bellevue-based Temporal rose to No. 2, now valued at $5 billion after raising $300 million for its platform that runs AI agents in production.
Another newly minted unicorn, XBOW, debuted at No. 35. The autonomous AI hacking platform from GitHub Copilot creator Oege de Moor raised another $35 million in May, extending a round that valued it at more than $1 billion.
Those are a few of the highlights from the latest edition of the GeekWire 200. Now in its second decade, the list pairs objective signals such as headcount, investment and followers with editorial judgment to identify and track the companies defining the region’s tech industry.
