Twenty years ago, King’s Cross was one of London’s most notorious red-light districts, plagued by drugs and crime. Today, it’s the beating heart of the UK’s AI revolution, home to over 3,600 AI startups that have collectively raised $12.1 billion since late July, according to Dealroom.
From seedy past to ‘Knowledge Quarter’
The area’s transformation is nothing short of remarkable. In the 1980s, crack and heroin made King’s Cross a major narcotics market, with syringes in tree trunks and gangs patrolling the streets. In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days, as Hussein Kanji, an investor at Hoxton Ventures, recalls.

The turning point came in the early 2000s when a real estate developer envisioned a new future for the area. By 2016, DeepMind — then newly acquired by Google — moved in, and a flood of AI startups followed, eager to be near the Google DeepMind magic. Today, the neighborhood is known as the “Knowledge Quarter,” hosting names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic.
The European Technology Network (ETN) recently moved into a glossy new office nearby, while University College London sits around the corner. Mixed in with the new developments are trendy food spots like Hoppers and BAO. A train from King’s Cross can get founders to Cambridge in 45 minutes to source talent or to Paris in two hours to strike a deal.

The AI gold rush and its impact on real estate
The demand for office space in King’s Cross has been staggering. Since the start of June, AI-related startups have leased more than 1 million square feet of office space in London, according to real estate firm Knight Frank. Prime rents in King’s Cross have risen 18% over the past three years, with the vacancy rate for conventional office space now just 0.9%.
“Demand has outstripped supply,” said Chris Dunn, a commercial insight associate at Knight Frank. The area is so hot that a VC firm allegedly won a deal by promising a founder office space in the neighborhood. “We stop at nothing to win deals [for] and to support founders, including helping them source office space when needed,” the firm told TechCrunch, declining to confirm or deny the rumor.
Around 18 months ago, BioCorteX moved from Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” said Nik Sharma, co-founder of BioCorteX. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.
Sovereignty and the future of UK AI
One of the big drivers of the area’s growth is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” said Saul Klein, co-founder of the VC firm Phoenix Court.
Robin Klein, co-founder of the firm, said the shutdown was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.
“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”
Simon Kohl, founder of Latent Labs, which has offices in King’s Cross and San Francisco, says the London office is growing faster, and he’s more bullish than ever. “The mood right now feels less like London trying to catch up and more like London becoming one of the default places to start a serious AI company,” he said.
Wayve, the autonomous vehicle unicorn founded in 2017, moved into King’s Cross in 2018 looking for a space that could double as a garage. “Ten years ago, building a frontier AI company from London felt like an unusual choice. Now it feels like an obvious one,” said co-founder Alex Kendall.
Talent wars and the road ahead
Unsurprisingly, London’s AI boom is causing a talent war. UK AI job postings have skyrocketed in recent years, per PwC data. When Anthropic announced it moved into town earlier this year, it listed a salary range of £260,000 to £630,000 for a machine learning research engineer — more than six times the average London salary of around £102,000 for the same role. Some founders are being forced to raise more and bigger rounds to keep up.
“The real test is whether more globally significant AI companies are founded, funded, and scaled from the U.K., while continuing to attract the world’s best talent to build them here,” said Zain Ali, founder of the King’s Cross-based AI legal firm Centuro. “If that continues to happen, King’s Cross won’t just be an AI hub. It’ll become one of the U.K.’s most important strategic assets.”
With the European Technology Network now established in the area and major players like OpenAI and Anthropic anchoring the neighborhood, King’s Cross has cemented its place on the global AI map. The question now is whether the UK can build the infrastructure to sustain this momentum — and turn a former red-light district into a lasting pillar of European tech independence.
