Synthesia raises $200 million Series E at $4 billion valuation to change how companies train and upskill their workforce

LONDON, January 26, 2025 – Synthesia, the AI video platform transforming how organizations create and share knowledge, announced today that it has raised a $200 million Series E funding round at a $4 billion valuation.

The round is led by existing investor Google Ventures (GV), with participation from Evantic, the venture fund founded by former Sequoia partner Matt Miller, and Hedosophia. Other existing investors NVentures (NVIDIA’s venture capital arm), Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital, and MMC Ventures also participated, reaffirming their commitment to Synthesia’s long-term vision.

As part of the transaction, Synthesia will also facilitate an employee secondary sale in partnership with NASDAQ at a $4 billion valuation. This will provide liquidity to long-time team members while enabling them to remain shareholders in the company’s future growth.

Helping people work better with AI

Synthesia plans to use the capital to build a category-defining company that will transform how employees learn, helping in areas such as enterprise learning and development, knowledge sharing, product marketing, and sales enablement with the help of agentic systems.

“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,” said Victor Riparbelli, Synthesia’s co-founder and CEO. “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.”

The UK’s Chancellor of the Exchequer, Rachel Reeves, said: “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.”

The company believes the next decade will be shaped by a transition from static, one-way content to interactive, conversational experiences powered by AI agents. At the same time, enterprises around the world are grappling with the challenge of keeping employees informed and skilled amid rapid change in products, regulations, and ways of working.

To address this, Synthesia is developing a new category of products focused on conversational Agents designed specifically for organizational learning and upskilling. These Agents will enable employees to interact with company knowledge in a more intuitive, human-like way by asking questions, exploring scenarios through role-play, and receiving tailored explanations rather than passively consuming training materials.

“Market opportunities like this do not come along often,” Riparbelli continued. “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.”

Building a category-defining AI company

“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,” said Vidu Shanmugarajah, general partner at Google Ventures. “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.”

The UK’s Business and Trade Secretary, Peter Kyle, said: “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.”

The UK’s Secretary of State for Technology, Liz Kendall, said: “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.”

Mayor of London, Sadiq Khan, said: “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.”

Early feedback from customers piloting Synthesia’s new agent-based products has been highly positive, with organizations reporting higher engagement and faster knowledge transfer compared to traditional formats. In response, Synthesia will make Agents a core strategic focus, alongside investing in further product improvements to its existing platform.

With this round, Synthesia is exceptionally well capitalized to execute on its vision. The company’s focus remains clear: build category-defining products, help organizations transform how they learn and share knowledge, and do it in a way that is safe, responsible, and sustainable for the long term.
