UK Data Center Startup Nscale Bets Big on Bellevue for Its First U.S. Engineering Hub
A British AI infrastructure company most Americans have never heard of just made its first real bet on U.S. soil, and it picked one of the most contested pieces of tech real estate in the country to do it. Nscale is opening its first U.S. engineering office in Bellevue, Washington, locking in roughly 24,000 square feet designed to house around 100 engineers and support staff, with the hub slated to open early next year, according to GeekWire's reporting on the announcement.
The location isn't an accident. Bellevue's Eastside neighborhood has become one of the most concentrated AI infrastructure corridors in the country, already home to engineering hubs for Anthropic, Databricks, CoreWeave, and UiPath, alongside Microsoft and Amazon's existing presence, a buildout pattern that mirrors what we've tracked in our coverage of AI industry statistics more broadly.
From Crypto Mining Spinoff to $14.6 Billion AI Infrastructure Player
Nscale's rise has been genuinely fast by any standard. The company emerged from stealth in May 2024 as a spinoff from crypto mining firm Arkon Energy, which had been struggling financially at the time, flagging "significant doubt" about its ability to survive in its own 2024 financial statements, according to TIME's reporting on the company's origins. Founder and CEO Josh Payne wound down Arkon and rebuilt the company entirely around AI data centers.
That bet paid off dramatically. Nscale raised $2 billion in March at a $14.6 billion valuation, the largest funding round of its kind in European history, with Nvidia itself participating in the round, according to CNBC's coverage of the raise. The company now operates data centers across the U.K., U.S., Norway, Portugal, and Iceland, and has struck major partnerships with Microsoft, OpenAI, and Meta. Payne has publicly stated his ambition to turn Nscale into a "$1 trillion hyperscaler" capable of competing directly with Amazon, Microsoft, and Google, a goal that would have sounded implausible for a two-year-old company in almost any other industry.
Why Nscale Is Called a "Neocloud"
Nscale belongs to an emerging category of infrastructure companies known as "neoclouds," built specifically to serve the compute needs of AI models rather than general-purpose cloud computing. That specialization is exactly why Nvidia CEO Jensen Huang has invested directly in the company, and why Nscale has attracted board members including former Meta COO Sheryl Sandberg and former UK deputy prime minister Nick Clegg.
The Bellevue hub fits into Nscale's broader strategy of building out U.S. engineering and operations teams to support its data center projects domestically, rather than running U.S. operations entirely from London, a pattern connected to what we've covered in our what is AI automation guide on the physical, geographically distributed engineering talent this buildout requires.
Why This Matters for Business
I've advised companies on AI infrastructure decisions for four years, and Nscale's rapid ascent from a struggling crypto miner to a $14.6 billion AI infrastructure company is a genuinely useful signal about how fast capital and talent are moving toward companies solving the physical compute bottleneck, not just the model layer. For businesses evaluating cloud and compute vendors, "neocloud" providers like Nscale are increasingly viable alternatives to the traditional hyperscalers, often with more flexibility and faster provisioning for AI-specific workloads.
For businesses in the Seattle and Bellevue region specifically, this signals continued competition for AI engineering talent locally, which has real implications for hiring and retention if you're competing for the same technical workforce.
The Fast Version
UK-based Nscale is opening its first U.S. engineering hub in Bellevue, Washington, designed for about 100 employees and slated to open early next year. The company rose from a struggling crypto mining spinoff to a $14.6 billion AI infrastructure player in under two years, backed by Nvidia and partnered with Microsoft, OpenAI, and Meta. Bellevue has become one of the most concentrated AI infrastructure hubs in the country, also home to Anthropic, Databricks, and CoreWeave.
