London AI Founders Are Building Global Companies From Britain

Mati Staniszewski described London’s current AI environment as more than a local upswing. The important change, he said, is that founders and employees increasingly believe a company can be built from Britain with global ambition from the outset.

Staniszewski pointed to London Tech Week as one expression of a broader buildout across London and Europe. His claim was not simply that there is more AI activity in the UK, but that the ambition attached to it has changed: more people now see the UK as a place where a startup can recruit serious talent, compete internationally, and try to lead rather than merely participate.

That matters because ElevenLabs has become an example in precisely that argument. Tom Mackenzie framed the company’s valuation — “north of 11 billion US dollars” — as evidence that a globally scalable AI company can be built out of the UK. Staniszewski accepted the premise, though he described the company less as an exception than as part of an emerging pattern.

ElevenLabs’ own origins are central to the point. Staniszewski said he and his co-founder both studied in the UK, and that most of the company’s early team was based in London. From the beginning, he said, the ambition was not to build a strong local company first and later internationalize, but to compete directly with the largest companies: “leading on benchmarks, leading with customers, leading on outcomes.”

“You can really build a global company from here from the start, and people want to do it,” Staniszewski said.

The result, as he described it, is a reinforcing cycle. Early employees at successful UK-based startups leave to create new companies. Others join domestic companies that are trying to scale. Senior people abroad increasingly consider returning to Britain or Europe to work on frontier AI companies. Staniszewski also pointed to Isomorphic Labs as another recent example adding momentum to the UK’s AI story.

When Tom Mackenzie pressed on whether the return of talent to the UK was significant rather than anecdotal, Mati Staniszewski said the shift had been especially visible over the last 12 months.

He broke the ecosystem change into several parts. Talent is moving differently. Risk appetite is changing. More people are willing to start companies from London and take what he called a “big swing” or “big bet.” Ambitious founders need ambitious employees, but they also need customers willing to try new suppliers before they are safe choices.

That is where Staniszewski contrasted Europe’s historical challenge with Silicon Valley’s advantage. One of Silicon Valley’s strengths, he said, is that large companies buy from small companies: they understand the risk, but still give early companies a chance to prove value and outcomes.

Staniszewski said he is now seeing more of that behavior in the UK and Europe. He named Revolut, Trainline, and Deliveroo as companies willing to work with frontier AI companies, including ElevenLabs. Those early commercial relationships can give smaller companies room to prove value and scale.

ElevenLabs, now a larger company itself, is also trying to participate in that loop. Staniszewski said the company is giving more chances to young UK and European startups. A stronger AI ecosystem, in his view, requires talent and founder risk-taking, but also established companies willing to absorb supplier risk earlier.

Tom Mackenzie asked whether ElevenLabs had faced pressure from US investors to move to San Francisco. Mati Staniszewski said the company’s investors were aligned around the idea that being in Europe gives ElevenLabs a real advantage.

The first advantage he named was talent. ElevenLabs has most of its people across Europe, he said, including almost 100 employees in the UK, with plans to scale that number to 200 over the next few months. He described the European team as including some of the hardest-working people in the company and argued that European employees want to work for ambitious frontier companies without having to leave the region.

The issue, Staniszewski said, is not whether a UK-founded AI company must eventually relocate closer to Silicon Valley. Remaining rooted in Europe helps ElevenLabs recruit people who want to be part of a core global team from London or other European cities.

At the same time, he did not present the US market as optional. ElevenLabs spends substantial time in the US and works with major customers there, including Meta. The company’s approach is a balance: retain the benefits of a European talent base while staying close to American customers and investors where necessary.

London’s AI ecosystem, in Staniszewski’s argument, has moved beyond a question of whether it has enough talent. He said the talent exists, the ambition is rising, the risk appetite is improving, and the customer base is beginning to behave in ways that let frontier startups prove themselves. ElevenLabs is both beneficiary and example of that shift: a UK-started AI company trying to compete globally while treating its European base as a strategic asset.
