Synthesia Raises $200M, With $4B Valuation

Synthesia has raised $200 million in Series E funding, lifting its valuation to $4 billion and reinforcing its position as a leading enterprise-focused AI video platform. The round was led by Google Ventures (GV), with participation from Evantic and Hedosophia, alongside existing investors including NVentures (NVIDIA’s VC arm), Accel, Kleiner Perkins, New Enterprise Associates, PSP Growth, Air Street Capital, and MMC Ventures. Alongside the raise, Synthesia announced an employee secondary sale in partnership with Nasdaq, allowing staff to sell a portion of their equity at the new valuation while remaining invested in the company’s future growth.

Synthesia enables organizations to convert text into video using AI-generated avatars and voices, a capability widely used for enterprise training and communications. In healthcare, the platform supports clinical education, compliance training, and onboarding for healthcare staff and researchers. Customers can use Synthesia’s prebuilt avatars or create custom digital avatars and voices, making it easier to scale training without traditional video production.

With the new funding, Synthesia plans to expand beyond passive video training into conversational, agent-driven learning experiences. These new products will allow employees to interact with AI agents—asking questions, role-playing scenarios, and receiving tailored explanations—reflecting growing demand for continuous upskilling and internal knowledge sharing. CEO and cofounder Victor Riparbelli said the company sits at the intersection of more capable AI agents and increasing enterprise pressure to reskill workforces, positioning Synthesia to define a new category in organizational learning.

The round follows rapid valuation growth for the UK-based company. Synthesia raised $180 million in Series D funding in early 2025 at a $2.1 billion valuation, after a $90 million Series C in 2023 that valued the company at $1 billion.
