The next generation of *British voice AI* companies is worth far more, and a good deal harder to place on a map.* --- In October 2012, Amazon bought **Evi**, a Cambridge company, for a reported $26 million, and its technology and team formed the foundations of what became Alexa today. Evi's pioneering AI voice assistant app had reached number one in the app store. Three years later, Apple bought another Cambridge business, namely **VocalIQ**, to make Siri more conversational, and the first person VocalIQ hired was *Nikola Mrkšić*, who went on to found **PolyAI** in 2017\. That company is now a University of Cambridge spin-out with customers including *Marriott, Caesars Entertainment and UniCredit,* a reported valuation of $750 million, and a stated position, in 2024, that American companies produced 70% of its revenue. We think it makes a useful test case for a question the sector that has largely avoided asking: when **British voice AI** does succeed, who ends up owning that result?[ ](https://app.dealroom.co/companies/evi?ref=entrepreneurplus.co.uk) --- ## A habit of being bought Britain has a long record of producing voice technology that other companies end up using. Beauhurst still lists **Evi Technologies** among the UK's top voice and vision companies by equity raised, marked as exited, with £4.5 million raised over its lifetime. In 2022 Spotify paid €93 million in cash for **Sonantic**, a London text-to-speech company, to expand text-to-speech across its platform. Those were exits of a familiar kind, small teams meeting a buyer that owned the distribution. What is happening now is on a different scale, and the two largest names, ElevenLabs and **PolyAI**, are still independent.[ ](https://www.beauhurst.com/blog/top-computer-vision-voice-ai-companies-uk/?ref=entrepreneurplus.co.uk) --- ## One company and a long tail UK computer vision and voice AI companies raised £635 million across 38 deals in the first quarter of 2026, more than the £461 million raised in the whole of 2025, with the surge driven by a step-change in **voice AI** investment. ElevenLabs tops the ranking with more than £600 million raised, about a fifth of everything the category has ever attracted, and the top five together hold 69%, the most concentrated top five the data provider says it has measured in any sector. The Beauhurst classification behind those figures also covers identity verification, autonomous vehicles and language services, so the public data cannot tell us how concentrated voice AI is on its own.[ ](https://www.beauhurst.com/blog/top-computer-vision-voice-ai-companies-uk/?ref=entrepreneurplus.co.uk) **ElevenLabs** began as a speech synthesis company, and it now sells text-to-speech, speech-to-text and voice cloning alongside its agent platform. It passed a unicorn valuation in early 2024, raised a $500 million Series D led by Sequoiain February, and is reportedly negotiating a secondary share sale at around $22 billion. That is a tender offer, in which existing shareholders sell shares rather than the company raising new money, and we have not found confirmation that it has completed. Its chief executive says the company is pacing at $600 million in annual recurring revenue, with more than half from classic enterprise customers.[ ](https://verdict.co.uk/?p=374809&ref=entrepreneurplus.co.uk) Beneath it, the picture thins quickly. **Speechmatics**, the Cambridge speech recognition company, has raised £75.9 million, roughly an eighth of ElevenLabs' total, and **Palabra AI**, a London real-time voice translation start-up, has raised £6.2 million at seed stage. Forty-three of Beauhurst's top 100 are seed-stage businesses. PolyAI's $86 million Series D in December was co-led by *Georgian, Hedosophia and Khosla Ventures*, with the British Business Bank adding £15 million, which means the lead cheques came from Canadian, British and American investors.[ ](https://www.beauhurst.com/blog/top-computer-vision-voice-ai-companies-uk/?ref=entrepreneurplus.co.uk) --- ## Where is ElevenLabs from? The question gets harder with ElevenLabs. London has been described as its biggest office, ahead of even New York, some company databases list its headquarters as New York, and when it opened its Soho office in 2024 it was described in print as Brooklyn-based. None of this is necessarily wrong, since the company is remote-first, with staff in more than 15 countries.[ ](https://www.nbcconnecticut.com/news/business/money-report/ai-voice-startup-elevenlabs-pushes-global-expansion-as-it-gears-up-for-an-ipo/3600214/?ref=entrepreneurplus.co.uk) The UK government plainly regards it as British. In June, ElevenLabs signed a memorandum of understanding with the **Department for Science, Innovation and Technology** to explore how voice AI can improve public services, including Welsh-language services, and said it would double its UK team this year and expand into a new London headquarters. In February it had agreed a three-year partnership giving the **UK AI Security Institute** access to its frontier voice models to study how well people can tell a human from an AI agent in natural conversation.[ ](https://elevenlabs.io/blog/uk-mou-and-expansion?ref=entrepreneurplus.co.uk) > *"a leading AI company choosing to base itself in the UK"* **\- Kanishka Narayan, Minister for AI and Online Safety** That sits uneasily with the listing question. ElevenLabs has said it would consider London as a place to list. Reports point to 2028, and when asked to confirm, its chief executive said the company is preparing the foundations for the next few years, and that the decision depends on timing and location.[ ](https://www.nbcconnecticut.com/news/business/money-report/ai-voice-startup-elevenlabs-pushes-global-expansion-as-it-gears-up-for-an-ipo/3600214/?ref=entrepreneurplus.co.uk) > *"whether we do it will depend on the time and place"* **\- Mati Staniszewski, co-founder and CEO, ElevenLabs** ***Read next:***[ *UK AudioTech Is Losing the Funding Race to AI*](https://entrepreneurplus.co.uk/uk-audiotech-is-losing-the-funding-race-to-ai/) --- ## What the phones sound like The clearest UK example is also one of the least glamorous. **A Ministry of Justice** transparency record published on 9 September describes **PolyAI's** virtual assistant answering the Prison Enquiry Centre line for five prisons, where friends and families of prisoners ask how-to questions about prison processes. It handles about 2,900 contacts a month and is expected to reach roughly 60,000\. A caller's speech is transcribed, matched to a predefined question and answered with a fixed response, and anything unrecognised, or flagged as a possible safeguarding concern, passes to a human adviser. Callers are told they are speaking to a virtual assistant and can ask for a person at any point, and the ministry says it chose the product for its conversational audio quality and market strength. That is an AI voice assistant built for predictability, with a human always one request away. Commercial deployments are larger. ElevenLabs says Trainline is using its agents to manage enquiries for millions of passengers across the UK, an announcement made at London Tech Week in June. Klarna runs first-line phone support for 35 million American customers on its technology, alongside Deutsche Telekom, Cisco and Adobe. Strip away the branding and most of this is contact centre automation, with AI voice agents taking the first call so that people handle the difficult ones, and the same logic underpins the wider pitch for customer service automation.[ ](https://www.pubrio.com/hi/companies/ffe3006e-0881-478b-89aa-c7d584f4bb9e?ref=entrepreneurplus.co.uk) Whether callers should be told is already a live question. ElevenLabs' chief executive says businesses should disclose when an agent answers, at least for now. The company says its safeguards include blocking the cloning of political and celebrity voices and requiring verification for voice cloning.[ ](https://techcrunch.com/2026/09/24/twenty-minutes-with-the-ceo-of-elevenlabs-now-reportedly-valued-at-22-billion/?ref=entrepreneurplus.co.uk) --- ## The squeeze under the headline numbers The concentration worries us because of how little protection it may buy. A year after predicting that audio models would be commoditised within a couple of years, ElevenLabs' chief executive said the quality gap at model level is still significant but should narrow over three to five years, and that he does not mind margins falling if sharing savings proves the product's value. He is also meeting his own customers as competitors: **Decagon**, a conversational AI platform, trained its voice product on ElevenLabs and now competes with it. Open-source large language models can handle informational calls, he said, while financial services calls involving authentication or refunds still lean on frontier models. If the economics of AI voice agents depend on whose models sit behind the call, the **voice AI** layer may protect its owners less than the valuations imply. ![](https://storage.ghost.io/c/05/a4/05a4a052-18ab-4836-8924-ec8b322c371c/content/images/2026/10/Modern-Sound-Lab-Overlooking-the-City.png) Voice AI Research Lab ## What we'd still like to ask These are the questions public records cannot answer. How much of **ElevenLabs'** revenue, headcount and decision-making sits in the UK right now, and what would make London the answer to the listing question? How much of the value **PolyAI** creates from its Cambridge research lineage stays in Britain, given a customer base weighted towards the United States? And who writes the Series A cheques that decide where the next ElevenLabs-scale outcome is owned? ***Will the next British voice AI company to reach that scale be owned by the people who built it?*** --- ## Editorial Note: This piece is based on secondary research.
