Synthesia Doubles Valuation to $4B on $200M Series E, Pivots Hard Into AI Agents and Structured Employee Liquidity

New updates have been reported about Synthesia.

Synthesia has raised a $200 million Series E round at a $4 billion valuation, nearly doubling its worth from a year ago as it passes $100 million in ARR on the back of AI-generated corporate training videos. The London-based company, which counts Bosch, Merck, and SAP among its enterprise customers, has built a profitable niche transforming internal training and knowledge delivery, and now plans to move beyond video into AI agents. The round was led by existing backer GV, with continued participation from Kleiner Perkins, Accel, NEA, NVentures, Air Street Capital, and PSP Growth, while new investors Evantic and Hedosophia joined the cap table. As part of the financing, Synthesia will run a coordinated secondary program via Nasdaq’s private markets unit, allowing early employees to sell shares at the official $4 billion valuation, rather than in ad hoc off-market trades.

CFO Daniel Kim positioned the secondary as a strategic retention and reward mechanism, providing “meaningful” liquidity while keeping Synthesia private and focused on multi-year growth. Strategically, management is elevating AI agents to a core investment priority alongside its existing video platform, with early pilots showing higher engagement and faster knowledge transfer than traditional training approaches. The company’s agents are being designed to let employees query internal knowledge, role-play scenarios, and receive personalized explanations in a more human-like way, aligning with a broader shift in enterprises toward board-level focus on upskilling and internal knowledge sharing. CEO Victor Riparbelli framed this as a convergence of two forces—rapid advances in AI agents and increasing pressure on companies to reskill and inform their workforces at scale. Founded in 2017, Synthesia now employs more than 500 people across offices in London, Amsterdam, Copenhagen, Munich, New York, and Zurich, and its use of a structured, cross-border Nasdaq-facilitated secondary is seen internally as a template that other late-stage U.K. startups may follow as they remain private for longer.
