ElevenLabs, Synthesia: The Rise of British AI Scale-ups

The United Kingdom stands out as a major player in the artificial intelligence sector, hosting some of the most promising scale-ups. Among them, Synthesia, ElevenLabs, and Luminance distinguish themselves through their innovations and rapid growth, helping to solidify the country's position as the third-largest tech hub globally, just behind the United States and China. With over 185 unicorns and a tech ecosystem valued at $1.2 trillion, the UK also ranks third for venture capital investments in AI.

Synthesia: AI Video at the Heart of Businesses

Synthesia, valued at $4 billion after a funding round in January 2026, specializes in creating videos using artificial intelligence. This technology allows companies to quickly produce video content for training, internal communications, or marketing, without the need for traditional filming. Synthesia aims to exceed $200 million in annual recurring revenue by 2026. Its platform, created in 2017, is already adopted by 90% of Fortune 100 companies. In France, it counts the Decathlon group among its clients, with whom it announced a partnership at the UK-France Summit last July.

Daniela Chordia-Doll, Vice President Europe at Synthesia, explains: "With clients like Decathlon, we start with very practical use cases such as training, onboarding, and internal communications—areas where video makes a significant difference. These initial pilot projects are designed to integrate directly into existing processes." She adds that "France is a big part of our strategy, and we want to be rooted in the French and European ecosystem, in addition to selling our solutions there," which translates into investments in local teams and a particular focus on European regulatory specifics.

Conversational Agents for Training

In addition to video creation, Synthesia is developing a new generation of products based on conversational agents. "These products enable teams to conduct role-playing and conversational scenarios such as sales conversations, customer interactions, and operational situations," explains Daniela Chordia-Doll. The goal is to allow employees to practice, receive feedback, and improve. "This benefits employees by helping them build confidence and skills without pressure, and it also benefits employers by allowing them to identify where teams struggle so they can tailor training accordingly," she details. The company's initial pilots demonstrate higher engagement and faster knowledge transfer than traditional training formats.

ElevenLabs: The Rise of Voice Synthesis

Another British success story, ElevenLabs recently raised $500 million in February 2026, bringing its valuation to $11 billion, more than triple its valuation from a year ago. The unicorn, which develops voice synthesis and conversational agent technology, now boasts an annual recurring revenue of over $330 million. "As a European AI champion, we are committed to making Europe competitive in the global AI race while ensuring that AI adoption remains safe, secure, and responsible," states Jonathan Chemouny, Go-To-Market Lead Europe at ElevenLabs.

France is among the fastest-growing markets for ElevenLabs, which has already attracted numerous clients there: Alan in healthcare, Adecco in recruitment, OpenClassrooms in education, and M6 and TV5Monde in media.

Voice Agents for Customer Service

The strongest opportunity identified by ElevenLabs in France lies in voice agents for customer service. "We recently announced a partnership with Revolut, and we are seeing rapid adoption in France," emphasizes Jonathan Chemouny. "What’s interesting is the acceleration of adoption by more traditional major players across a wide range of industries: luxury, healthcare, travel. They are testing and finding that the agents are ready for large-scale production." This momentum has been bolstered by a major update to the platform: ElevenLabs' voice agents now offer faster response times and improved expressiveness while supporting over 70 languages. "This allows European and French companies to scale easily, not just in Europe but also globally," the lead clarifies.

The startup is also focusing on the local ecosystems of the countries where it invests: participating in events, sponsoring, press relations, and supporting entrepreneurs through a grant program offering three months of free credits to startups, as well as hackathons organized in 14 European cities.

Luminance: AI for Law and Compliance

Born from research at the University of Cambridge, Luminance has established itself as a reference in AI applied to legal professions. With a funding round of $75 million announced in February 2025, bringing the total raised in 12 months to over $115 million, the British scale-up now works with over 1,000 organizations across more than 70 countries.

In this hypergrowth phase, France is among Luminance's strategic priorities. "Alongside Germany, France is one of our main European markets after the UK, and we see enormous growth potential there," explains Eleanor Lightbody, CEO of Luminance. Among the company's French partners are Dassault Systèmes, Lactalis, and Banijay.

Eliminating "Corporate Amnesia"

Luminance stands out in the AI market with its specialization in high-level legal analysis. "Our platform supports legal teams at every stage of the contract lifecycle, from drafting and negotiation to repository management and continuous workflow automation," details Eleanor Lightbody. "Our latest version eliminates 'corporate amnesia' by preserving institutional memory, ensuring that the context behind contracts is captured, not just the outcome," she explains. This means that legal teams can identify risks earlier and unlock new business opportunities through AI document analysis.

France and, more broadly, the European Union, with their complex regulatory environments, represent an ideal playground for Luminance. "Companies must comply with both local legislation and European regulation, which heightens the demand for a legal AI solution capable of managing complexity. With the European AI Act coming into force and increased scrutiny on compliance and risk management, organizations need AI systems they can deploy with confidence," emphasizes the CEO.

A Call for Enhanced Collaboration

Beyond commercial successes, these three companies share a common vision: that of a Europe capable of competing with the United States and China in the AI race. To achieve this, collaboration between the British and French ecosystems appears to be an essential lever. "The UK has clearly stated its desire to be an 'AI superpower,' and France aims to be an 'AI power.' There is already a shared ambition," notes Eleanor Lightbody from Luminance.

For Jonathan Chemouny from ElevenLabs, both countries have complementary strengths: "France has an exceptional talent pool, and Paris is quickly becoming one of the world's leading AI hubs, with Station F, Meta's FAIR, Mistral, Yann LeCun's AMI, etc. This proves that the UK and France can be competitive not only locally but also internationally."

Opportunities for collaboration between the two ecosystems abound, as Daniela Chordia-Doll from Synthesia details, whose CEO Victor Riparbelli participated in the CEO roundtable at the UK-France Summit. She mentions “more cross-border programs and networking through regular joint events, such as UK-France tech weeks, common summits, and shared platforms.”

The challenge, according to Eleanor Lightbody, is to "facilitate the smooth operation of businesses across both markets. This involves reciprocal visa arrangements for technical talent, joint research initiatives that translate into commercial applications, and interoperable rather than divergent regulatory frameworks."

The message conveyed by these three promising scale-ups is clear: if Europe wants globally competitive AI champions, it must create ecosystems that cooperate.
