London-based AI video platform Synthesia has raised $200 million in a Series E funding round at a valuation of $4 billion. The round was led by existing investor Google Ventures (GV), with participation from Evantic and Hedosophia, a venture fund founded by former Sequoia partner Matt Miller.
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 deal, Synthesia will work with Nasdaq to help employees sell their company stock at a $4 billion valuation. This allows long-term team members to access cash while maintaining a stake in the company’s future growth.
The UK company aims to use the funding to create a company that leverages advanced systems to transform the way employees learn, with a focus on areas such as employee development, knowledge sharing, product marketing and sales support.
AI video platform for business
Synthesia, led by Victor Riparbelli, is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, Synthesia develops products that power visual communications and enterprise skills development, helping people work better and stay at the heart of successful organizations.
“Synthesia was founded on two core beliefs: first, that AI makes the cost of content creation zero; and second, that AI video provides a better and more engaging way for organizations to communicate and learn,” said Victor Riparbelli, co-founder and CEO of Synthesia.
Early customer feedback for Synthesia’s new agent-based product has been very positive, with organizations reporting higher engagement and faster knowledge transfer than traditional formats.
In response, Synthesia is investing in further product improvements to its existing platform while placing agents at the core of its strategy.
“This round of funding is about expanding that vision. We are witnessing a rare convergence of two major changes: technology change as the capabilities of AI agents increase, and upskilling and internal knowledge sharing at the board level. “We intend to build a company that is decisive at that intersection by combining our AI video know-how with our ability to build and integrate AI technology into products and services that solve real business needs.”
The company believes that the next decade will be shaped by the shift from static, one-way content to interactive, conversational experiences powered by AI agents.
At the same time, companies around the world are grappling with the challenge of keeping employees informed and skilled as products, regulations, and ways of working change rapidly.
To address this, Synthesia is developing a new category of products focused on conversational agents designed specifically for organizational learning and upskilling. Rather than passively consuming training materials, these agents allow employees to interact with company knowledge in a more intuitive and human way by asking questions, exploring scenarios through role-play, and receiving customized explanations.
