Synthesia, developer of artificial intelligence software that enables companies to create video content for training, communications, and knowledge sharing without traditional production processes, has raised $200 million in a Series E funding round valuing the business at $4 billion. The round was led by existing investor Google Ventures, with participation from Evantic and Hedosophia, alongside continued backing from NVentures, Accel, Kleiner Perkins, New Enterprise Associates, PSP Growth, Air Street Capital, FirstMark, and MMC Ventures.
As part of the transaction, the company will also carry out an employee secondary sale in partnership with NASDAQ at the same valuation, allowing long-serving employees to access liquidity while remaining shareholders.
Synthesia said the new funding will be directed toward expanding its AI-driven products for enterprise learning and development, internal communications, product marketing, and sales enablement. The company’s platform uses artificial intelligence to generate video presentations featuring digital avatars and multilingual voiceovers, which organizations use to distribute training and informational content at scale.
The company is also developing conversational AI agents intended to support workforce training and upskilling. These products are designed to allow employees to interact with company knowledge through question-and-answer exchanges, simulated scenarios, and personalized explanations, rather than relying solely on pre-recorded materials.
Victor Riparbelli, Synthesia’s co-founder and chief executive officer, said the company was built on the expectation that artificial intelligence would lower the cost of producing content and make video a more effective medium for organizational communication and learning. He said the latest funding round would support further development of AI video technology combined with agent-based systems aimed at addressing enterprise training needs.
The investment prompted comments from UK government officials, including Chancellor of the Exchequer Rachel Reeves, who cited the company as an example of domestic technology firms contributing to employment and economic growth. London Mayor Sadiq Khan also referenced Synthesia’s presence in the capital as part of London’s role in artificial intelligence research and investment.
Founded in 2017 and headquartered in London, Synthesia provides AI-generated video software to corporate customers and reports that its tools are used by a large share of Fortune 100 companies. The company said it will continue investing in its core video platform alongside new agent-based products, with a focus on deploying artificial intelligence in a responsible and sustainable manner.
