London-based Synthesia has raised $200 million in a Series E funding round, valuing the company at $4 billion, nearly double its valuation a year earlier. The round was led by existing investor GV, with participation from Kleiner Perkins, Accel, New Enterprise Associates, NVentures, Air Street Capital, and PSP Growth, alongside new investors Evantic and Hedosophia.
Founded in 2017 by Victor Riparbelli and Steffen Tjerrild, Synthesia surpassed $100 million in annual recurring revenue in 2025, driven by enterprise demand for AI-generated training content. The company plans to invest further in AI agents that enable interactive, human-like engagement with corporate knowledge, while also facilitating a structured employee liquidity program with Nasdaq as it continues to operate as a private company.
