Synthesia Raises $200 Million in Series E Funding, Valuation Now at $4 Billion
British startup Synthesia has recently closed a $200 million Series E funding round, increasing its valuation to an impressive $4 billion. This valuation marks a significant jump from just a year ago when the company was valued at $2.1 billion.
Synthesia, known for its AI platform that helps companies create interactive training videos using AI-generated avatars, has been able to establish a profitable business model in the corporate training sector. With clients such as Bosch, Merck, and SAP, the London-based company surpassed $100 million in annual recurring revenue in April 2025.
The successful growth and profitability of Synthesia have attracted the attention of venture capitalists, leading to the recent Series E funding round. The round was led by existing investor GV (Google Ventures) and saw participation from other previous backers, including Kleiner Perkins, Accel, NEA, NVentures, Air Street Capital, and PSP Growth.
In addition to existing investors, new entrants such as Evantic and Hedosophia are joining the cap table. Synthesia also plans to facilitate an employee secondary sale in partnership with Nasdaq to provide early team members with an opportunity to turn their shares into cash.
While Synthesia is not going public at this time, the company’s CFO, Daniel Kim, emphasized that the employee secondary sale is primarily aimed at giving employees a chance to benefit from the company’s success while maintaining a focus on long-term growth.
Looking ahead, Synthesia is expanding its offerings to include AI agents that will allow clients’ employees to interact with company knowledge in a more intuitive and human-like manner. Early pilots of the AI agents have shown promising results, with customers reporting higher engagement and faster knowledge transfer.
CEO Victor Riparbelli highlighted the importance of AI agents in addressing the challenges faced by enterprises in training their workforce amid rapid changes in the market. The company plans to invest in further product improvements and make AI agents a core strategic focus.
Founded in 2017, Synthesia now has over 500 team members and offices in London, Amsterdam, Copenhagen, Munich, New York City, and Zurich. The company’s coordinated secondary sale is a unique move in the British startup scene but may become more common as private companies stay private longer.
