The UK May Have A Voice In Ai

Europe’s AI sector has grown accustomed to playing catch-up. Capital has flowed more slowly than in Silicon Valley, valuations have lagged US peers and commercial breakthroughs have often arrived elsewhere first. That pattern is now being tested by a London-founded start-up whose ambitions are expanding almost as fast as its valuation.

ElevenLabs, the artificial intelligence voice company, is in early discussions over a funding round that could value the business at about $11bn. If completed, the deal would almost double the company’s valuation within a matter of months and make it the most valuable AI start-up ever created in the UK.

People familiar with the talks say ElevenLabs is seeking to raise several hundred million dollars from investors, although discussions remain at an early stage and terms could still change. The negotiations come just four months after a secondary share sale that valued the group at $6.6bn, highlighting the pace at which investor expectations have accelerated.

Founded in London in 2022 by Polish entrepreneurs Mati Staniszewski and Piotr Dabkowski, ElevenLabs has built a business around AI-generated speech that aims to replicate human tone, cadence and emotion with increasing realism. Its technology is now used across customer service, media localisation, audiobook production and language dubbing.

The company’s rapid rise reflects more than enthusiasm for AI as a theme. ElevenLabs has demonstrated an unusual ability to turn technical capability into revenue. Last year it generated $330mn in annual recurring revenue, a figure that places it among the fastest-growing AI software companies globally.

That commercial traction helps explain the intensity of investor interest. ElevenLabs has already attracted backing from some of the most influential names in venture capital, including Sequoia Capital, Andreessen Horowitz and Iconiq Capital, alongside NEA, Smash Capital and FT Ventures.

If the latest fundraising succeeds, it would place ElevenLabs ahead of other high-profile UK and European AI groups. London-based autonomous driving company Wayve was in talks last year about raising capital at a valuation of roughly $8bn before new money. Cloud computing group Nscale, backed by Nvidia, was valued at around $3bn in September.

An $11bn valuation would also put ElevenLabs within touching distance of Mistral, one of the few European groups developing large-scale “frontier” AI models, which was valued at close to $12bn late last year.

The contrast with the US remains stark. OpenAI, the creator of ChatGPT, is among the world’s most valuable private technology companies, with a valuation estimated at around $500bn. It is in talks with investors over a funding round that could raise up to $80bn and push its valuation beyond $800bn, according to people briefed on the discussions.

Against that backdrop, ElevenLabs’ ascent stands out as an exception rather than the rule for European AI. While the region has produced world-class research, it has struggled to match the US on fundraising scale and speed of commercialisation. Investors have often complained that Europe lacks companies capable of turning AI breakthroughs into globally competitive businesses.

ElevenLabs’ strategy has been deliberately transatlantic. While founded in London, the company has established a significant presence in New York and has incorporated in the US to make it easier to access American capital. It also operates offices in Warsaw, Bengaluru and Tokyo, reflecting its ambition to serve enterprise customers worldwide.

That global footprint has helped it scale quickly. In January 2025, ElevenLabs raised $180mn at a valuation of $3.3bn. Just eight months later, it doubled its valuation to $6.6bn in a deal that allowed employees to sell about $100mn of stock. At the time, the company said its annual recurring revenue had reached $200mn, underlining the speed of its growth.

The latest funding talks suggest that momentum has continued. Investors are increasingly drawn to AI businesses with clear, repeatable revenue rather than speculative research bets. Voice technology, in particular, is seen as an area where adoption is already well under way, driven by demand for automation in call centres, content localisation and digital assistants.

Still, the pace of valuation growth brings risks. AI markets remain crowded, competition is intensifying and customers are becoming more selective as spending normalises after the initial boom. Maintaining growth rates that justify an $11bn valuation will require continued product development and expansion into new use cases.

For the UK technology sector, however, ElevenLabs represents something rare: a home-grown AI company capable of competing at scale on the global stage. Whether it can sustain that position remains to be seen, but its rise has already altered perceptions of what European AI start-ups can achieve.

If the funding round closes on the terms being discussed, ElevenLabs will not just set a new benchmark for UK AI valuations. It will also serve as a test case for whether Europe can produce commercially dominant AI companies, not just promising ideas.
