Synthesia, a London-based generative AI startup specializing in AI-generated videos and avatars, has successfully closed a $180 million Series D funding round led by prominent venture capital firm NEA. The investment values the company at an impressive $2.1 billion, establishing it as the United Kingdom’s largest generative AI startup by valuation, according to data platform Dealroom.
Founded in 2017, Synthesia has positioned itself as a market leader in enterprise AI video production. The company offers a comprehensive suite of products designed to help businesses create professional video content at scale. These tools include custom AI avatar creation, an AI screen recorder for video editing, and an innovative AI video assistant that can automatically transform web pages into video format.
CEO and cofounder Victor Riparbelli emphasized the company’s success in building what he describes as “the market-leading AI video platform for enterprise.” The startup’s client roster includes major technology companies like Zoom and UiPath, which leverage Synthesia’s platform to produce diverse content ranging from customer service videos to corporate training materials.
What sets Synthesia apart from other European AI companies is its global reach. Riparbelli noted that over half of the company’s revenue originates from the United States, demonstrating the startup’s ability to compete on an international scale rather than remaining a regional player.
The Series D round attracted participation from both existing and new investors. Google Ventures continued its support alongside new backers including WiL (World Innovation Lab), Atlassian Ventures, and PSP Growth. This latest funding brings Synthesia’s total capital raised to $330 million, reflecting the strong investor appetite for growth-stage AI startups in the current market.
The fresh capital will fuel several strategic initiatives. Synthesia plans to continue refining its existing product suite while expanding its video publishing platform capabilities. The company is also developing AI agents to assist users throughout the video production process. Geographic expansion is another priority, with plans to strengthen presence in Japan, North America, and Australia over the coming year.
The funding round included an 18-slide pitch deck that showcased Synthesia’s vision and market opportunity to potential investors.

Our Take
Synthesia’s $2.1 billion valuation validates the massive market opportunity for specialized generative AI applications in enterprise settings. While much attention has focused on large language models, this funding demonstrates that vertical-specific AI solutions solving concrete business problems can achieve unicorn status and beyond. The company’s success with major clients like Zoom and UiPath proves that enterprises are willing to pay premium prices for AI tools that deliver measurable ROI through reduced production costs and faster content creation. The geographic expansion strategy is particularly astute—targeting Japan, North America, and Australia positions Synthesia in markets with high enterprise spending and strong demand for digital transformation. As video becomes increasingly central to corporate communications, training, and marketing, Synthesia is well-positioned to capture significant market share in what could become a multi-billion dollar category.
Why This Matters
This funding round represents a significant milestone for both Synthesia and the broader European AI ecosystem. As the UK’s largest generative AI startup by valuation, Synthesia demonstrates that European companies can compete globally in the rapidly evolving AI landscape, particularly against well-funded American competitors.
The investment highlights the growing enterprise demand for AI-powered video creation tools as businesses seek to scale content production while reducing costs. Traditional video production is expensive and time-consuming; Synthesia’s platform addresses this pain point by enabling companies to generate professional videos quickly using AI avatars and automation.
The strong investor appetite, particularly from major players like NEA and Google Ventures, signals confidence in the commercial viability of generative AI applications beyond text-based tools like ChatGPT. Video generation represents a massive market opportunity as organizations increasingly prioritize video content for training, marketing, and customer engagement.
Synthesia’s success also reflects broader trends in AI adoption across enterprises, where companies are moving from experimentation to production-scale deployment of AI tools. The startup’s ability to generate over half its revenue from the US market demonstrates the global scalability of AI solutions and the willingness of enterprises to invest in transformative technologies.
