London-based AI video platform Synthesia has raised a $200 million Series E funding round at a $4 billion valuation. The round was 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.
As part of the transaction, Synthesia will work with NASDAQ to help employees sell their shares at a company valuation of $4 billion. This allows long-time team members to access cash while still keeping a stake in the company’s future growth.
A UK company aims to use the funds to create a company that transforms how employees learn, focusing on areas such as employee development, knowledge sharing, product marketing, and sales support, leveraging advanced systems.
AI video platform for business
Led by Victor Riparbelli, Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the centre of successful organisations.
“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 organisations to communicate and learn,” said Victor Riparbelli, Synthesia’s co-founder and CEO.
Early customer feedback on Synthesia’s new agent-based products has been highly positive, with organisations reporting higher engagement and faster knowledge transfer than with traditional formats.
In response, Synthesia will make Agents a core strategic focus, alongside investing in further product improvements to its existing platform.
“This funding round is about scaling that vision. We see a rare convergence of two major shifts: a technology shift as AI agents become more capable, and a market shift in which 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,” he adds.
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 organisational 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.
