London-based AI video platform Synthesia has raised $200 million in a Series E funding round led by Google Ventures, propelling the company’s valuation to $4 billion. This latest investment comes from a mix of new and existing investors, including Evantic, a venture capital firm founded by former Sequoia investors, as well as Hedosophia. Notable existing investors such as NVentures (the venture capital arm of Nvidia), Accel, Kleiner Perkins, NEA, PSP Growth, and Air Street Capital also participated in this funding round.
Founded in 2017, Synthesia specializes in video generation technology that creates lifelike avatars for both internal and external communications within organizations. The recent funding brings the company’s total capital raised to over $500 million. It follows a $180 million Series D round in January 2025, which had valued Synthesia at $2.1 billion.
Plans for Conversational AI Development
Synthesia plans to allocate a portion of the newly acquired funds to develop a new category of conversational AI agent products. These products are intended to enhance organizational learning and upskilling. CEO Victor Riparbelli noted the unique opportunity presented by current market conditions. “We see a rare convergence of two major shifts: a technology shift with AI agents becoming more capable and a market shift where upskilling and internal knowledge sharing have become board-level priorities,” he stated. “Market opportunities like this do not come along often.”
Last year, Synthesia reportedly engaged in discussions with software giant Adobe regarding a potential acquisition valued at approximately $3 billion. However, those negotiations did not result in an agreement, as reported by the Information.
As part of this funding round, Synthesia will also give employees the opportunity to sell secondary shares, enhancing employee engagement and investment in the company’s future growth.
This latest investment signals a strong belief in the future of AI-driven communication tools, reflecting a growing trend among businesses to adopt innovative technologies for enhancing workplace efficiency and learning.
