Synthesia, a London-headquartered AI video platform focused on helping organizations create and share knowledge, said it has raised a $200 million Series E round at a $4 billion valuation, positioning the company to accelerate product development aimed at enterprise learning, internal communications, and upskilling.
The financing was led by existing backer Google Ventures (GV), with participation from Evantic, the venture fund founded by former Sequoia partner Matt Miller, and Hedosophia. Existing investors NVentures (NVIDIA’s venture capital arm), Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital, and MMC Ventures also took part.
Alongside the primary round, Synthesia said it will facilitate an employee secondary sale in partnership with NASDAQ at the same $4 billion valuation, offering liquidity to longer tenured team members while allowing them to remain shareholders.
Synthesia said it will use the new capital to pursue what it described as a category-defining opportunity at the intersection of two trends, more capable AI agents and rising enterprise urgency around workforce reskilling, knowledge sharing, and training. The company is developing conversational Agents intended for organizational learning, with the goal of enabling employees to interact with company knowledge through questions, scenario exploration, role play, and tailored explanations, rather than consuming static training materials.
Synthesia said early customer feedback from pilots of its agent-based products has been positive, with reported increases in engagement and faster knowledge transfer compared with traditional formats. The company said Agents will become a core strategic focus, alongside continued investment in its existing platform.
Founded in 2017, Synthesia said it is used by over 90% of the Fortune 100 and is headquartered in London with offices across Europe and the US.
KEY QUOTES
“Synthesia was founded on two core beliefs: first, that AI will bring the cost of content creation down to zero. And secondly, that AI video provides a better, more engaging way for organizations to communicate and learn. This funding round is about scaling that vision. We see a rare convergence of two major shifts: a technology shift with AI Agents becoming more capable, and a market shift where upskilling and internal knowledge sharing have become board-level priorities. We intend to build the defining company at that intersection, by combining our know-how in AI video with our ability to build and integrate AI technologies into products and services that solve real business needs.”
“Market opportunities like this do not come along often. We are at a unique point in time where technology enables agents that can truly understand and respond, and where enterprises are under unprecedented pressure to reskill and upskill their workforce. Synthesia is building the infrastructure and experiences that will power this shift.”
Victor Riparbelli, Co-founder and CEO, Synthesia
“Synthesia is a UK success story, creating new jobs and opportunities in this country. It shows that by backing innovators to start, scale and stay in the UK through better access to finance and generous tax reliefs, we can turn the promise of AI into better-paid jobs and long-term growth across the UK.”
Rachel Reeves, UK’s Chancellor of the Exchequer
“Enterprises are moving beyond asking whether they should adopt AI for learning and communications. The question now is how fast they can do it, how broadly it can be used, and how deeply they can integrate it into their workflows. We’ve been partners with Synthesia since the Series B and have long believed in Victor and the team’s vision. Today, we’re even more convinced that Synthesia has the product, the team, and the traction to become the category leader in AI-powered learning experiences.”
Vidu Shanmugarajah, General Partner, Google Ventures
“Synthesia’s success is a powerful example of the UK’s global leadership in artificial intelligence. British AI companies are not only developing world-class technology but are applying it to real business challenges at scale. Investments like this show our Industrial Strategy in action, creating high-value jobs, and driving long-term economic growth across the country.”
Peter Kyle, UK’s Business and Trade Secretary
“We’re determined to build a world-class environment where British companies can start strong, scale rapidly and choose to grow their future here in the UK. Synthesia is a brilliant example of exactly what that ambition looks like in action. This backing isn’t just a vote of confidence in a British AI firm – it’s a clear signal of the huge appetite investors have to get behind our AI sector. With companies like Synthesia calling the UK home, we can go further and faster in our push for AI to bring jobs, growth, and national renewal to hard-working people up and down the country.”
Liz Kendall, UK’s Secretary of State for Technology
“London is a global hub for AI innovation and investment, and having organisations like Synthesia base their headquarters in London’s Knowledge Quarter will help us shape the next technological wave. I’m committed to ensuring our capital benefits from the huge potential of AI and Londoners are not left behind. That’s why I recently announced a London AI taskforce to support Londoners navigate a more competitive global job market, as we build a better, fairer, more prosperous London for everyone.”
Sadiq Khan, Mayor of London
